APPLICATIONS
The B-XMD&D-XMD series are specially
designed for applications where a group of polar
power supplies are isolated from the input
power supply in a distributed power supply
system on a circuit board.
These products apply to:
1) where the voltage of the input power supply is
fixed (voltage variation ≤±10%);
2) where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) where the regulation of the output voltage
and the output ripple noise are not demanded.

RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
REACH COMPLIANT INFORMATION
This series has proven that this product does not contain harmful chemicals, it also has
harmful chemical substances through the registration, inspection and approval.
