I have never seen these before but my searching says it is a capacitor array. The one in the picture says 102, and the page that picture came from says 1nf @ 50v. No one seems to have them… or I have it wrong. The one’s on the board I have say 220 instead of 102, so I assume this means the one’s I need are 2.2nf? 50v…
I’d like to replace these on the new board with SMD part(s).
First, is this really a Capacitor Array (of 2 caps?)
Second, is it 2.2nf?
Third, who makes these?
Fourth, trying to move away from throug-hole components, what would be a SMD equilivent?
Hi,
Welcome to the Digikey tech forum. I did some searching and wasn’t able to come up with a part that matches. Any chance you can show us a photo of the part on the PC board for reference.
So, this is a Communication board of sorts. I have not followed traces yet, but I can see they flow to the socketed RS-422 chips and the edge connectors… So, like a TVS diode or sorts?
I would say this is a 220pf, 22 is the value and the 1 is how many zeroes to add making 22 with one zero or 220pf. Just like the first part with 102 marked on it. The value is 10 with two zeroes or 1000pf which is the same as 1nf. Take a look at Digikey part 490-9790-1-ND as a possible option.
It’s a filter to prevent radio frequencies from either making the system malfunction, or prevent the system from emitting signals strong enough to violate FCC radio regulations.
Using Digikey part 490-9790-1-ND, the only similar SMD I found is 490-6946-1-ND, most of it attributes match 490-9790-1-ND except for its Voltage rating which is lower at 25 Volts.
