of available output power in a previously rated
2W package capable of operation over the full
industrial temperature range of -40ºC to 85ºC3.
Available in an industry standard SIP package,
with a pin compatible power upgrade path from
the 1W NME/NKE and 2W NML series’, they are
ideally suited for providing local supplies on
control system boards with the added benefit of
1kVDC galvanic isolation.

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 MEE3 series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The MEE3 series has been recognized by Underwriters Laboratory for functional isolation. Both input and output should normally be maintained within SELV limits i.e. less than
42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation sys-
tem. The part could be expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides of the
barrier must be regarded as operating at an unsafe voltage and further isolation/insulation systems must form a barrier between these circuits and any user-accessible circuitry
according to safety standard requirements.
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 MEE3 series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enameled wire. While
parts can be expected to withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any material, including this enamel (typically
polyurethane) 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 be reduced by 20% from specified test voltage.
This consideration equally applies to agency recognized parts rated for better than functional isolation where the wire enamel insulation is always supplemented by a further
insulation system of physical spacing or barriers.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of
260°C for 10 seconds. The pin termination finish on the SIP package type is Tin Plate, Hot Dipped
over Matte Tin with Nickel Preplate. They are backward compatible with Sn/Pb soldering systems.

SAFETY APPROVAL
The MEE3 series has been recognized by Underwriters Laboratory (UL) to UL 60950 for functional isolation in a maximum still air ambient temperature of 63°C and/or case tempera-
ture limit of 91°C. Case temperature measured on the face opposite the pins. File number E179522 applies.
The MEE3 series of converters are not internally fused so to meet the requirement of UL 60950, an input line fuse should always be used. An anti-surge 2.5A should be used for
MEE3S05xxSC models, and an anti-surge 1A should be used for MEE3S12xxSC models. All fuses should be UL approved and rated to at least the maximum allowable DC input
voltage.
