Jim, how much current capability do you need?

I'm looking for an off the shelf transient/noise filter for 12V (yeah, 14.4 or 13.8V)


The application is that there's motors and relays running off the 12V bus, which is noisy, but I have stuff needing a cleaner 12V and 5V (getting 5V from 12V is easy with automotive USB power widgets).

Ideally with power pole connectors.


I could design something with LC and back to back Zeners, etc. but I would rather just buy something.
