Need help to identify a three lead passive component
That is not a dual cap. It is a 3 pin tantalum with two ground wires to reduce ESR/impedance and to avoid mounting it with wrong orientation. It has a rating of 22 uF and 25V and the K is a tolerance marking. Alternatives include 2 pin tantalum and ceramic caps as long as above ratings are known, but without schematics it is hard to know how important cap it is.
