The TPSB225M025R0900 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated 2.2 µF at 25 V with ±20% tolerance. The 900 mΩ ESR (equivalent series resistance) sets the ripple-current handling and self-heating under AC load — relevant for output filtering in DC-DC converters or decoupling on power rails where the ripple frequency is below a few hundred kilohertz.
Product status is Active per KYOCERA AVX — no end-of-life notice, no mandatory last-time-buy window. Availability is confirmed at RFQ; quantities are sourced through independent distribution channels.
