I believe it is a 22uh 1/2 watt correct?

You want one rated at 100ma or more, wattage isn't normally a choke rating, except for eBay sellers.   I called up a range of them, and here's a suitable part from Digikey: https://www.digikey.com/en/pro...c/78F220J-RC/1305996

There must be some "conspiracy" with eBay Asia sellers where I can't find a good deal on 1/2W inductors any more.  I got my lifetime supply a few years back on eBay for a couple pennies each.

In any case, if you're willing to try aliexpress.com and wait, there's a seller there where you can get 22uH 1/2W inductors for 5-10 cents each in small quantity (free shipping from Asia):

22uh 50 pcs for less than 2 bucks

These are so-called 0410 sized (04mm diameter x 10mm length) packages which is just a tad larger than the DigiKey inductor that GRJ links.  If you're familiar with 1/2 Watt resistors, those too are about 0410 in size...duh.

These are what I use for rolling stock to be used with DCS  As the datasheet suggests, these support 410 mA of current so more than adequate for LED passenger car lighting.
