Please read Cautions and warnings and Page 5 of 7

Cautions and warnings
Storage
• Store thermistors only in original packaging. Do not open the package prior to storage.
• Storage conditions in original packaging: storage temperature −25 °C ... +45 °C, relative humidity ≤75%
annual mean, <95% maximum 30 days per annum, dew precipitation is inadmissible.
• Do not store thermistors where they are exposed to heat or direct sunlight. Otherwise, the packing material
may be deformed or components may stick together, causing problems during mounting.
• Avoid contamination of thermistor surface during storage, handling and processing.
• Avoid storage of thermistors in harmful environments like corrosive gases (SOx, Cl etc).
• Use the components as soon as possible after opening the factory seals, i.e. the polyvinyl-sealed packages.
• Solder thermistors within the time specified after shipment from EPCOS.
For leaded components this is 24 months.
Handling
• NTC thermistors must not be dropped. Chip-offs or any other damage must not be caused during handling
of NTCs.
• Do not touch components with bare hands. Gloves are recommended.
• Avoid contamination of thermistor surface during handling.
• Washing processes may damage the product due to the possible static or cyclic mechanical loads (e.g.
ultrasonic cleaning). They may cause cracks to develop on the product and its parts, which might lead to
reduced reliability or lifetime.
Bending/ twisting leads
• A lead (wire) may be bent at a minimum distance of twice the wire’s diameter plus 4 mm from the
component head or housing. When bending ensure the wire is mechanically relieved at the component
head or housing. The bending radius should be at least 0.75 mm.
Soldering
• Use resin-type flux or non-activated flux.
• Insufficient preheating may cause ceramic cracks.
• Rapid cooling by dipping in solvent is not recommended.
• Complete removal of flux is recommended.

Important notes at the end of this document.
Mounting
• Ensure that no thermo-mechanical stress occurs due to production processes (curing or overmolding
processes) when thermistors are sealed, potted or overmolded or during their subsequent operation. The
maximum temperature of the thermistor must not be exceeded. Ensure that the materials used
(sealing/potting compound and plastic material) are chemically neutral.
• Electrodes/contacts must not be scratched or damaged before/during/after the mounting process.
• Contacts and housing used for assembly with the thermistor must be clean before mounting.
• Ensure that adjacent materials are designed for operation at temperatures comparable to the surface
temperature of the thermistor. Be sure that surrounding parts and materials can withstand the temperature.
• Avoid contamination of the thermistor surface during processing.
• The connections of sensors (e.g. cable end, wire end, plug terminal) may only be exposed to an
environment with normal atmospheric conditions.
• Tensile forces on cables or leads must be avoided during mounting and operation.
• Bending or twisting of cables or leads directly on the thermistor body is not permissible.
• Avoid using chemical substances as mounting aids. It must be ensured that no water or other liquids enter
the NTC thermistors (e.g. through plug terminals). In particular, water based substances (e.g. soap suds)
must not be used as mounting aids for sensors.
Operation
• Use thermistors only within the specified operating temperature range.
• Use thermistors only within the specified power range.
• Environmental conditions must not harm the thermistors. Only use the thermistors under normal
atmospheric conditions or within the specified conditions.
• Ensure that no significant thermo-mechanical stress occurs during operation due to the mounting situation.
Fixtures must not overstress the sensor by an excessive mechanical preload.
• Contact of NTC thermistors with any liquids and solvents shall be prevented. It must be ensured that no
water enters the NTC thermistors (e.g. through plug terminals). For measurement purposes (checking the
specified resistance vs. temperature), the component must not be immersed in water but in suitable liquids
(e.g. Galden).
• Avoid dewing and condensation unless thermistor is specified for these conditions.
• Bending or twisting of cables and/or wires is not permissible during operation of the sensor in the
application.
• Be sure to provide an appropriate fail-safe function to prevent secondary product damage caused by
malfunction.

Display of ordering codes for EPCOS products
The ordering code for one and the same EPCOS product can be represented differently in data
sheets, data books, other publications, on the EPCOS website, or in order-related documents such as
shipping notes, order confirmations and product labels. The varying representations of the
ordering codes are due to different processes employed and do not affect the specifications of
the respective products. Detailed information can be found on the Internet under

Important notes
Page 7 of 7
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical
requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application. As a
rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them
than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or failure
before the end of their usual service life cannot be completely ruled out in the current state
of the art, even if they are operated as specified. In customer applications requiring a very high
level of operational safety and especially in customer applications in which the malfunction or
failure of an electronic component could endanger human life or health (e.g. in accident
prevention or life-saving systems), it must therefore be ensured by means of suitable design of the
customer application or other action taken by the customer (e.g. installation of protective circuitry
or redundancy) that no injury or damage is sustained by third parties in the event of malfunction or
failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as hazardous). Useful information on this will be found in our Material
Data Sheets on the Internet (www.epcos.com/material). Should you have any more detailed
questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently,
we cannot guarantee that all products named in this publication will always be available.
The aforementioned does not apply in the case of individual agreements deviating from the
foregoing for customer-specific products.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of
the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association (ZVEI).
