The WRB_YT-3W series are specially designed for
applications where a wide range input voltage power
supplies are isolated from the input power supply in a
distributed power supply system on a circuit board.
These products apply to:
15
℃
1.5mm from case for 10 seconds
300

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