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 needi

Jim; PowerWerx (down your way) may have what you want. The URL is: https://powerwerx.com/dc-line-noise-filter-powerpole-connectors <https://powerwerx.com/dc-line-noise-filter-powerpole-connectors> 73
Chuck W5PR yes - but it's unclear if they have the transient clipping aspect - Esp the sort of generic "noise filter" - most equipment designed for automotive use (i.e. radios, amps) has transient
What you really need is an LTC3045-1. If you don't want to build it, then purchase an eval board. One board will get you several output voltages. Rick N6RK The application is that there's motors and
Are you thinking LT3045 - that's orders of magnitude better than I need. And it will blow up with a 50V transient on the input. _______________________________________________ _______________________

Jim, how much current capability do you need? 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
probably around an amp or so. 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 wi
I would point out that the LT3045-1 has provisions built into it to combine multiple instances of the chip to provide max current that is a multiple of 500 mA. The scheme avoids wasting significant p

probably around an amp or so. Perhaps using a DC-to-DC converter would be the way to go. DC Power conditioners seems to be a thing for marine electronics. I don't know if this particular unit has th
In my experience, most EMI is common mode, and is not accurately described on data sheets. 73, Jim K9YC _______________________________________________ _______________________________________________
In my experience, most EMI is common mode, and is not accurately described on data sheets. but here, I'm not looking at EMI - I'm concerned about differential mode transients (inductive things like r
It seems like a Maxim MAX16171 would fit the bill. It handles an input protection range of -42 through +76 V, and with an external FET, any reasonable current you need. I didn't look into an applicat

I was considering a differential mode transient a form on conducted EMI. I figured one of those immunity specs would cover that, but perhaps not. When I was hunting around I stumbled into this MFJ pr
