The MEJ1 series are single and dual output DC/
DC converters in a 7 pin SIP package style offering
an isolation and insulation upgrade path from
the NMV & MEV1 series’. The MEJ1 series has
UL60950 and ANSI/AAMI ES60601-1 recognition,
which makes it ideal for applications where safety
and miniaturisation are of paramount importance.

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 MEJ1 series of DC/DC converters are all 100% production tested at 5.2kVDC for 1 second and qualifcation tested at 7kVDC for 1 second,
5.2kVDC for 1minute.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The MEJ1 series has been recognized by Underwiters Laboratory for various voltages, please see safety approval section below.
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 specified test voltage.
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The MEJ1 series has been tested by Underwriters Laboratory (UL) to meet ANSI/AAMI ES60601-1 medical safety standard providing the following MOOP (means of operator
protection), in a maximum ambient temperature of 85°C and/or case temperature limit of 130°C (case temperature measured on the face opposite the pins): 1 MOOP based upon
a working voltage of 200 Vrms max and 280 Vpk max., between Primary and Secondary and between Primary and its Enclosure. File Number E202895 applies.
UL 60950
The MEJ1 series has been recognized by Underwriters Laboratory (UL) to UL 60950 for basic/supplementary insulation to a working voltage of 250Vrms in a maximum ambient
temperature of 85°C and/or case temperature limit of 130°C (case temperature measured on the face opposite the pins). File number E151252 applies.
FUSING
The MEJ1 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.
MEJ1x03xxSC 1A
MEJ1x05xxSC 1A
MEJ1x12xxSC 500mA
MEJ1x15xxSC 500mA
MEJ1x24xxSC 250mA
All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage.
RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. The pin termination finish
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. For further information, please visit www.murata-ps.com/rohs

APPLICATION NOTES
Minimum load
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 and start up
Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product
series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.

Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1
1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC/DC converter
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
C2
than 100mΩ at 100 kHz
C3
100nF multilayer ceramic capacitor, general purpose
R1
450Ω resistor, carbon film, ±1% tolerance
R2
50Ω 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.
