What are the key features of SUS10053R3BP?

4.5 V to 9 V input range for nominal 5 V rails
Regulated 3.3 V single output for logic supplies
500 V ac input-to-output isolation for board-level protection
6-pin SMT power module format for compact assembly

What is SUS10053R3BP used for?

Used in compact industrial controls, instrumentation, and communications boards that need an isolated 3.3 V rail from a nominal 5 V input. The 500 V ac isolation and SMT module format suit distributed power, mixed-signal interface, and embedded I/O designs where board space is limited.

Frequently Asked Questions

Can SUS10053R3BP regulate a 3.3 V rail from a 5 V industrial bus?

Yes. SUS10053R3BP accepts a 4.5 V to 9 V input and provides a regulated 3.3 V output, making it suitable for isolated 5 V distributed-power rails.

How does the 500 V ac isolation affect mixed-signal board placement?

The 500 V ac I/O isolation helps separate noisy input power from sensitive 3.3 V logic, while the 6-pin SMT module simplifies compact board-level isolation layouts.

Which checks matter before approving an alternate Cosel module?

Confirm the alternate module matches the 4.5 V to 9 V input range, 3.3 V output, 6-pin footprint, and isolation rating before production procurement.
