The WRA_YMT-2W & WRB_YMT-2W Series are specially
designed for applications where
a wide range input
15
℃
voltage power supplies are isolated from the input power
supply in a distributed power supply system on a circuit
board.
1.5mm from case for 10 seconds

Short circuit protection
Cooling
These products apply to:
Continuous, automatic recovery
Free air convection
1) Where the voltage of the input power supply is wide
range ( voltage range ≤2:1 ) ;
2) Where isolation is necessary between input and output
(Isolation Voltage ≤1500VDC);
Epoxy Resin (UL94-V0)
Package material
MTBF
3) Where the regulation of the output voltage and the
output ripple noise are demanded.
