PART NUMBER SYSTEM
B0503S-3
APPLICATIONS
The B0503S-3 is designed for application where isolated
output is required from a distributed power system.
These products apply to where:
1) Input voltage variation ≤ ±10%;
2) 1.5KVDC input and output isolation;
3) Regulated and low ripple noise is not required.
Such as: digital circuits, low frequency analog circuits, and
IGBT power device driving circuits.
