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):
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.
