PRODUCT OVERVIEW
The NXJ1 series is a new range of low cost, lower
profile, fully automated manufacture surface
mount DC/DC converters. The NXJ1 series
automated manufacturing process with substrate
Embedded Transformer, offers increased product
reliability and repeatability of performance in a
halogen free, iLGA inspectable package. The NXJ1
series, industry standard footprint is compatible
with existing designs.
The NXJ1 series has a MSL rating 2, and is com-
patible with a peak reflow solder temperature of
245˚C as per J-STD-020 and J-STD-075.

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 recognized by Underwriters Laboratory, please see saftey 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 recognized 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.
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 recognized and rated to at least the maximum allowable DC input voltage.

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.
