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 specied time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions NMJ series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 5.2kVDC for 1 second.
A question commonly asked is, What is the continuous voltage that can be applied across the part in normal operation?
The NMJ series has been recognized by Underwriters Laboratory to 300Vrms for Supplementary Insulation and 150Vrms for Reinforced Insulation.
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. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specied test voltage.
SAFETY APPROVAL
The NMJ series has been recognised by Underwriters Laboratory (UL) to UL60950 for supplementary insulation up to 300Vrms and reinforced insulation up to 150Vrms at a
maximum ambient temperature of 75C, measured on the side opposite the pins. File number E151252 applies.
RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260C for 10 seconds. The pin termination nish
on this product series is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The series is backward compatible with Sn/Pb soldering
systems.
