I am preparing to rebuild an mpu and gathering components. I have a couple that I am unsure about. If you see the pic, L1 and L2 are what confuse me. You can see the component and the schematic listing pictured. (.22mh?) I am not familiar with this component and I'm looking to replace with an equivalent piece. Anyone able to tell me what I am looking for here?
Thanks

Quoted from zacaj:

Those are inductors, measured in henries. I've used https://www.digikey.com/product-detail/en/5321834 in the past.

Ok, these say .22 so what units matter as far as an equivalent or possibly an upgrade? Do I need to match .22 and is there voltage specs or anything else I need to know? Or are the ones you show ok for this specific .22 application? Sorry not familiar at all with inductors.

I don't know much about inductors either so I just matched up the specs. 220nH = 0.22uH if my math is right.

Ok, sounds good. Thanks!

Those are inductors (a.k.a. chokes). You want .22 uh (micro henries). Great Plains Electronics should have.

By the way, I only replace them if they are obviously damaged or corroded. Yours look fine.
