The TPSB225K025R0900 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 2.2 µF at 25 V with ±10% tolerance. The 900 mOhm ESR sets the ripple current handling and self-heating in a DC-DC output filter or bulk decoupling slot. Operating from -55 °C to 125 °C, it fits avionics, downhole instrumentation, and satellite power buses where the ambient range exceeds industrial limits.
The equivalent series resistance is 900 mOhm, which is the dominant loss term for ripple current and self-heating in a power rail application.
