1.5mm from case for 10 seconds
300
The
WRA_YD-2W&WRB_YD-2W
series
are
0.2
specially designed for applications where
a
wide
Free air convection
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:
1) Where the voltage of the input power supply is wide
range (voltage range≤2:1);
Short circuit protection
Case material
Continuous, automatic recovery
Plastic(UL94-V0)
MTBF
1000
K hours
Weight
4.8
g
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.
