Noise filter for DC-DC boost converter

[asiadiy]

I am using a DC to DC converter, 12v input, 48V output. I would like to be sure the output is clean before going into my new 3E amp board.


Any recommendations for a 15A (700watt) filter that can operate at 48VDC? Seems difficult to source on that can accept 48V.


Thanks

Perhaps if you confirm that there is noise on the 48V line (with your intended load), and what it is?

You can probably find a suitable inductor...

I'm assuming my cheap Ebay DC-DC boost switching type converter will not be very clean. Maybe too pessimistic?

I just bought a filter, rated 50v 15a. Maybe good insurance?

It has 3 inductors and 2 caps. I plan to wire this between the boost converter and amplifier.

I think we can safely assume that all that silicone sealant on your dc converter will mop up any noise...

The murata looks like a good choice.
