capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.

PRODUCT OVERVIEW
The NTV series of 3kV isolation miniature
surface mounted DC/DC converters employ
leadframe technology and transfer moulding
techniques to bring all of the benefits of IC style
packaging to hybrid circuitry. The co-planar-
ity of the pin positions is based upon IEC
191-6:1990. The devices are suitable for all
applications where high volume production is
envisaged.

1. If components are required in tape and reel format suffix order code code with -R, e.g. NTV0505MC-R.
2. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
3. 12V input types have typically 3% less load regulation change.

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, ap-
plied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions NTV series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 3kVDC for 1 minute.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
For a part holding no specific agency approvals, such as the NTV series, 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 system. 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 NTV 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 there-
fore 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 insula-
tion system of physical spacing or barriers.
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%.

RoHS COMPLIANCE, MSL AND PSL INFORMATION
This series is compatible with RoHS soldering systems and is also backward compatible with Sn/Pb soldering systems.
The NTV series has a process, moisture, and reflow sensitivity classification of MSL1 PSL R7F as defined in J-STD-020
and J-STD-075. This translates to: MSL1 = unlimited floor life, PSL R7F = Peak reflow temperature 245°C with a
limitation on the time above liquidus (217°C) which for this series is 60sec max. The pin termination finish on this product
series is Gold with a plating thickness of 0.05 microns minimum.
