• High-speed response: Driving up to about 1/3 of self-
resonant frequency (in several ten kHz)
• Low power consumption: Can be retained at the leakage
currentstateof100μAorless
• Very small size: 1/10 or smaller than conventional
multilayer actuators
• RoHS/REACH compliant
Multilayer Piezoelectric Actuators
AE Series Resin Coated
Overview
Multilayer piezoelectric actuators are ceramic elements
used to convert electrical energy into mechanical energy
such as displacement or force by utilizing the piezoelectric
longitudinal effect.
KEMET’s multilayer piezoelectric actuators are produced
based on our unique element structure design and
piezoelectric ceramic materials with high electrostrictive
factors. Compared to conventional piezoelectric
actuators, they are smaller in size but can generate higher
displacements and forces at low voltages.
The Resin Coated AE series actuators feature compact size
and a wide variety of shapes for applications such as ultra-
finepositioningmechanismanddrivesources.
Applications
Typical applications include positioning, auto focusing
ofopticalsystems,pumps,mass-flowvalves,vibration
source, vibration controls, sensors, image stabilization
of DSC, mirror/prism positioning, manipulators, motors
and printers.

Environmental Compliance
All KEMET Multilayer Piezoelectric Actuators are RoHS and REACH Compliant.
Article 33(1) of the REACH Regulation states that manufacturers and importers of articles (products) are required to notify
theircustomersofthepresenceofanySubstancesofVeryHighConcern(SVHC)intheirproductsexceeding0.1%byweight
and provide instructions on safe use of the product.
KEMET Corporation reports regarding the Article 33(1) of REACH Regulation as follows:
1. Applicable Product:
Multilayer piezoelectric actuators (AE, AER, ASB, ASL and AHB Series).
2. Report for content of REACH SVHC list:
Theproduct(s)abovecontainasubstancebymorethan0.1wt%perproductweightthatwaspublishedinthe8thupdateof
the REACH SVHC substances (December 19, 2012).
3. Regarding safety of the multilayer piezoelectric actuators (Piezoceramic products):
The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as a main ingredient.
It is chemically stable, with minimum risks toward the human body or environment within the intended use of the product.
Please note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.
4. Technical product information on the multilayer piezoelectric actuators (Piezoceramic products):
The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide
(PZT) has been established, and there is no alternative material that can exhibit superior performance than PZT at this
moment. Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) Annex III (7c.1).
5. Responsibility of piezoceramic manufacturers:
Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the
article 33 of the REACH regulation.

Reliability
The majority of failure modes on multilayer piezoelectric actuators are short-circuits due to degraded insulation. Although
thecauseofdegradationofinsulationhasnotbeenclarified,ithasbeenfoundthatthefailureratevariesgreatlybetween
static uses (DC voltage application) and dynamic uses (pulse voltage application). Like other electrical components,
piezoelectric actuators can be affected by humidity as well as applied voltage and ambient temperature.
This section describes reliability guidelines for static and dynamic usage of the resin coated type actuators. Reliability of
our multilayer piezoelectric actuators is represented by MTTF (mean time to failure) in case of static usage.
DC Voltage Application
The acceleration factors have been obtained empirically for each of the drive voltage, ambient temperature and relative
humidity based on many experimental results. The MTTFr in actual applications is estimated using equation (1) below with
MTTFs observed under accelerated conditions as the reference value.
(1) MTTFr = MTTFs × Av × Ah × At
MTTFr : Estimated value
MTTFs : Reference value (= 500 hours)
Av: Acceleration factor for drive voltage = (150/Vr)3.2 Vr: Actual voltage (V)
Ah: Acceleration factor for relative humidity = (90/Hr)4.9 Hr:Actualrelativehumidity(RH%)
At: Acceleration factor for ambient temperature = 1.5(40−Tr)/10 Tr:Actualambienttemperature(°C)
Thefollowingcalculationismadeforthecaseofuseat25°C,60%RHand100V.
MTTFr = 500 × (150/100)3.2 × (90/60)4.9 × 1.5(40−25)/10
= 500 × 3.66 × 7.29 × 1.84
≈24,500hours(2.8years)
Pulse Voltage Application
In driving dynamic applications, temperature rises as a result of self-heating allowing the component not to be affected
by the humidity, thus extending the operational lifetime. This phenomenon is explained as a result of the humidity factor
elimination caused by the self-heating.
Since the self-heating value is affected by multiple factors such as the element’s shape, pulse waveform and frequency, it
isdifficulttoestimatetheactualrisingvalue.Therefore,thelifeoftheactuatorcannotbedeterminedbyusinganequation,
unlikethecaseofDCvoltageapplications.WhentestingtheAE0203D08DFpart,therewasnofailureconfirmedafter500

User’s Guide
Fixing Method
• Carefully prevent the piezoelectric actuators from being bent, twisted or applied tensile force.
Reference: Twisting and Tension Tolerance
Reference Value Remarks
Twisting Force 3 × 10−1 N • m or less For an actuator which generates a force
of 800 N (compression resistance).
Tension
50 N or less
• Install the actuator so that the center axis of the generated displacement is aligned with the center axis of the load.
• Epoxy-based adhesives are recommended for bonding. Select adhesives that have high rigidity and allow for medium
thickness so that the generation force and displacement cannot be deteriorated. Also, do not form adhesives on the side
of the actuator.
• When thermosetting resin is used, perform polarizing treatment (see caution section) after the adhesive is settled.
• The resin coated type is weak to the tensile force due to its structure and may be broken when tensile forces are applied
onto the device. Using the device in the state that constantly applies compression is effective against any mechanical
damage.Thepressureappliedtothiselementshouldbekeptat20%to50%oftheforcegeneratedbythiselement
(compression resistance).
• Install the element so that the axis of generated displacement is vertical to the mounting surface.
Driving Method
• Connecttheredleadwiretothepositive(+)terminalofthepowersupply.Alsopreventreversevoltageapplication.
• In driving applications, it is necessary to take consideration of hysteresis, ringing, creep, and other similar phenomenons.
• For pulse driving, it is also necessary to be aware of self-heat generation, charge/discharge current, and the power
supply’s impedance.

Connect the red lead wire to the positive terminal of the power supply.
Carefully avoid electric shock since a high voltage is in use.
Never apply excessive tension to a lead wire. Do not handle the product by picking up or moving the lead wire.
Do not disassemble the case of the metal sealed type.
Machining of the actuator element and replacement of the lead wire are prohibited.
Do not handle the resin-coated type AE series with bare hands. Otherwise, the reliability of the element
would be degraded.
Do not wash resin-coated type AE series by organic solvant.
Avoid excessive physical shock resulting from, for example, dropping. Otherwise, the internal piezoelectric ceramic
element may be damaged.
If the actuator is exposed to high temperature above 100 or if it is used after long storage period more
than three months, it should be polarized by using the circuit confi guration and conditions shown below.

Do not apply voltage exceeding maximum rating voltage, or do not do rapid charging and discharging.
These might lead to degradation of the reliability or mechanical fracture.
Do not use the actuator in high concentration of highly infl ammable gas. Otherwise, ignition may occur.
Use the actuator so as not to cause bending, twisting or tension. Furthermore, align the center axis of displacement
of the actuator with the center axis of the mechanical load.
Drive the actuator so that the rising speed is more than three times as much as the resonance period in
order to prevent the device from damaging by ringing.
Store the resin-coated type AE series preferably in a dry atmosphere desirably below 40% RH at ordinary
temperatures 5 to 40˚C. Avoid condensation on the product surface.
Store actuators where there is no vibration.
These products must be handled properly as industrial waste. When disposing, please contact your local waste
