identify part from car audio amplifier

[darkkon]

hello everyone, i was wondering if someone can direct me of what this part is and where to purchase it? it came off of a car audio amplifier american bass vfl 100.1

when the multimeter is switched to 'ohms 200' the part on the outer legs reads .4

there are numbers on the part read '2220 A 10'

It is a bypass capacitor, a PCB equivalent of a feedthru cap.
In general it only has to do with EMC compliance, and if you replace it with a piece of wire, your amplifier should work.

yes, that is what it is supposed to measure. Any of the outer legs to the middle leg should read open circuit with a VOM. If you have a capacitance meter, you should be able to measure 0.0022uF across any outer leg to the inner leg IIRC

does anyone know where i can buy this part?

Looks like it has ferrite beads on 2 leads.

The 3 leads and ferrite bead made me think it was a ceramic resonator.
