The B_(X)T-1W Series are specially
designed for applications where a group of
polar power supplies are isolated from the
input power supply in a distributed power
supply system on a circuit board.

1) Where the voltage of the input power
supply is fixed (voltage variation ≤ ±10%);
2) Where isolation is necessary between
input and output (isolation voltage
≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not
demanding.

device driving circuits.
Note :1.the B_XT-1W series have no 3,6,7 pin. For example B0505XT-1W.
2. B_XT-1W :UL-60950-1 pending.
