Anyone sell off the shelf inductors in the range of 1 Henry? Everyone
I call can make it custom but doesn't have off the shelf items.

Here's one.

CA03 Pi Filter Choke 1 Henry 500 mA Ł46.33

Better yet (smaller, less costly):

CB01 Pi Filter Choke 1 Henry 200 mA Ł33.44

You may be able to use one side of a commonly available transformer. How
much current does it need to carry?

Analog filter or power?
How much current?
Do you hace a limit on Resistance?
AC ripple?

This is for a filter so current will be below 1ma. Tolerance +/- 20%,
size should be less than a few CC's. I found some:

www.rencousa.com

Has an incredible line up of up to 47H in a shielded package .3" x
..725" @ 25$ each with two week lead time in quantities of 10, qty 50 =
$9!

I am not sure what spec I need for AC ripple. Its for a filter @
10khz. Resistance should be less than 500 ohms. (see my other post, I
found some at www.rencousa.com)

Do an INDUCTOR search. I got 20 hits. lots to choose from, Tiny SM and small
through hole. You can get samples (up to five) of each free! So you should
find something suitable.

Also try "Top Magnetic" for those values. They DO have them as standard. Maybe
also samples.

There are about 250 Inductor company's at this time. Most are very keen on
providing samples for getting designed into a product.

Some type of audio filter, no doubt. Is there a reason you can't use an
op-amp circuit with resistors and capacitors?

Bear in mind that the Q of the 1 H inductor may be fairly low.
