SMD Package

Internal surface mounted design

International standard pin-out

A_(X)T-1W series is specially designed for applications where an isolated voltage is required in a distributed power supply system. It is suitable

for:

1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);

2.Where isolation is necessary between input and output (isolation voltage ≤1000VDC);

3.Where do not has high requirement of line regulation , load regulation and the ripple & noise of the output voltage;

Such as: pure digital circuits, low frequency analog circuits, and IGBT power device driving circuits.
