Filter Choke

BC · 22nd September 2004, 12:04 AM

Hi Guys,
I would like to use an iron core or large air core inductor used in low pass filters for woofers as a power supply choke filter. This would be cheaper than a special made choke. Of course, it would be low DCR. Here are some parameters:

Max Voltage: 55VDC
Nominal Current: 2 ADC
Max Current: 10 ADC
Inductance: 1mH to 10mH (haven't decided)

Sorry, but I am having problems presenting a schematic. Basically it is:
Bridge Rectifier-- Filter Cap--Inductor(choke)--Filter cap--Output

Pi network filter. Any help would be appreciated. Thanks.

Inductors made for crossover in an amp?

Thanks Geek,
It mostly answered my question. I do want mH, and I can get a laminate core inductor. My real concerns were the ratings for AC vs. DC voltage/current.
Thanks again,
Bruce
