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.

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.

  • \$\begingroup\$ Fortunately there are often compatible replacements, with the same parameter and same PCB footprint. It doesn't even have to be the same brand. The chart above can help you select a filter with the same dB loss patern. \$\endgroup\$

  • \$\begingroup\$ @Fredled Fortunately there are often compatible replacements, with the same parameter and same PCB footprint. It doesn't even have to be the same brand. true, but it isn't that easy to find a "fully replacement" to the product above since it has a maximum DC current rating of 2A. Today's popular T type tiny LC filter modules have a maximum current rating of 250mA or maybe 500mA. \$\endgroup\$ Mar 18 '20 at 10:13

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.

    \$\begingroup\$ You may well have found the correct part. A summary of what the part is and what lead you to it would help make this a good answer. Maybe include section of the datasheet showing the part and its specifications. \$\endgroup\$

  • \$\begingroup\$ Can you explicitly say that it is a T-filter rather than implying it as a search term? \$\endgroup\$

  • \$\begingroup\$ Wow! Thank you very much everyone for the quick and extremely thorough answer/research! I really appreciate it. Note: Yes, I tried the google image search first but I was looking for a 4 pin/leads capacitor and/or inductor coil. \$\endgroup\$
