The TPSC226M025R0275 is a molded tantalum capacitor from the KYOCERA AVX TPS series, offering 22 µF capacitance with ±20% tolerance and a 25 V DC voltage rating. This combination makes it a fit for bulk decoupling on 12 V or 5 V power rails where the 25 V rating provides headroom for transients without excessive derating. With a 275 mOhm equivalent series resistance (ESR), it handles ripple currents in switch-mode power supply outputs and DC-DC converter filters while keeping self-heating in check.
The molded case construction provides mechanical stability under thermal cycling.
