FEATURES

Efficiency up to 86%

Isolation voltage: 1.5K VDC

Operating temperature range: -40℃ to+105℃

Miniature SMD package

Internal surface mounted design

No external component required

International standard pin-out

B_XT-2WR2 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 ≤1500VDC);

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 relay-driven circuits.
