TECHNICAL NOTES
ISOLATION VOLTAGE
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage,
applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions NXJ1 series of DC-DC converters are all 100% production tested at 4.2kVDC for 1 second and have been qualification tested at 4.2kVDC for 1 minute.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The NXJ1 series has been recognised by Underwriters Laboratory, please see safety approval section for more information. When the insulation in the NXJ1 is not used as a safety
barrier, i.e. provides functional isolation only, continuous or switched voltages across the barrier in excess of 1kV are sustainable. Long term reliability testing at these voltages
continues. Please contact Murata for further information.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials,
construction and environment. The NXJ1 series has a PCB embedded isolated transformer, using FR4 as an insolation barrier between primary and secondary windings. While parts
can be expected to withstand several times the stated test voltage, the isolation capability does depend on the FR4 insulation properties. Any material, including FR4 is susceptible
to eventual chemical degradation when subject to very high applied voltages thus implying that the number of tests should be strictly limited. We therefore strongly advise against
repeated high voltage isolation testing, but if it is absolutely required, that the voltage should be reduced by 20% from specified test voltage.
This consideration equally applies to agency recognised parts rated for better than functional isolation where the insulation is always supplemented by a further insulation system
of physical spacing or barriers.
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The NXJ1 series is recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) based upon a working voltage of 250
Vrms max, between input and output.
UL 60950
The NXJ1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 200Vrms and for basic insulation to a working
voltage of 250Vrms.
Creepage and clearance is 4mm.
FUSING
The NXJ1 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below.
Input Voltage, 3.3V: 1A
Input Voltage, 5V: 0.5A
Input Voltage, 12V: 0.25A
All fuses should be UL recognised and rated to at least the maximum allowable DC input voltage.
RoHS COMPLIANCE AND MSL INFORMATION
This series is compatible with Pb-Free soldering systems and is also backward compatible with Sn/Pb soldering systems.
The NXJ1 series can be soldered in accordance with J-STD-020 and have a classification temperature of 260°C and
moisture sensitivity level 2. The termination finish on this product is Gold with plating thickness 0.12 microns.

CHARACTERISATION TEST METHODS
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1 1µF X7R m ultilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC-DC converter
C2 10µF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC-DC converter with an ESR of less
than 100m at 100 kHz
C3 100nF multilayer ceramic capacitor, general purpose
R1 450 resistor, carbon film, ±1% tolerance
R2 50 BNC termination
T1 3T of the coax cable through a ferrite toroid
RLOAD Resistive load to the maximum power rating of the DC-DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.

APPLICATION NOTES
Short Circuit Performance
Advisory Notes Minimum Load
The NXJ1 series is not hermetically sealed, customers should ensure that parts
are fully dried before input power application.
The minimum load to meet datasheet specification is 10% of the full rated load
across the specified input voltage range. Lower than 10% minimum loading will
result in an increase in output voltage, which may rise to typically double the
specified output voltage if the output load falls to less than 5%.
Capacitive Loading & Start Up
Typical start up times for this series, with a typical input voltage rise time of 2.2s with resistive only load, and with added output capacitance of
47F, are shown in the table below.
Output Ripple Reduction
By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max.
Component selection
Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended. The voltage rating should be at least
twice (except for 15V output), the rated output voltage of the DC-DC converter.
Inductor: The rated current of the inductor should not be less than that of the output of the DC-DC converter. At the rated current, the DC resistance of the inductor should
be such that the voltage drop across the inductor is <2% of the rated voltage of the DC-DC converter. The SRF (Self Resonant Frequency) should be >20MHz.

TEMPERATURE DERATING
The derating graphs are based on the following airflow conditions, for a component mounted on a 25mm x 25mm copper covered pcb and are provided for information
only. Actual performance in an application is likely to differ from these results, and a customer should evaluate the thermal environment the NXJ1 is used in, to achieve a
recommended maximum component surface temperature of 85°C for the NXJ1S0303SC or 105°C for all other variants.
