Please help identify this component, marked 222F

Question

I think it's a capacitor marked "222F" (2,200pF) +/-1%. However, it seems encased and has 4 pins instead of 2. Two seem to be for the capacitor and the other two for the plastic looking bracket around it. First I thought it was a coupled inductor of sort. Peaking inside a small opening it looks like a capacitor based on the color. It's about 3mm x 3mm x 2mm square. The arrows point to the mounts, there is one more on the other side not showing in the picture. Thank you.

Answer 1

They are Panasonic's "Coil Type EMI Filter" as given in Armandas' answer. I just wanted to add some extra info.

They are mostly T type LC filters:

The numbers indicate the capacitance inside the module. So, "222" means 2200pF. The module acts as 3rd order LPF and each model has a different cutoff frequency:

Panasonic has stopped manufacturing those, so the whole series became obsolete. But if you want to replace it (unlikely) you may be able to find at Digikey.

Answer 2

Looks like it could be Panasonic ELKEA222FA T-Filter.

EDIT: How to find a the right part:

1. Seeing a capacitor in the middle, gives a clue that it may be a T-filter.
2. Google smd t filter and browse images.
3. If an image looks similar, follow the links to find the part number.
