0.22 µF, 25 V, 0805 — molded tantalum for tight board spots
The TAJR224M025RNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, 0.22 µF ±20% rated at 25 V in an 0805 case. The 21 Ohm ESR is the number to watch for ripple current handling — at 25 V and 0.22 µF, the self-heating from ripple stays low in typical decoupling roles, but the ESR dominates impedance above a few hundred kHz.
Active production — sourced per BOM quantity
The TAJ series is a broad molded-tantalum family; this R-case code (0805) is a common footprint that sees wide distributor stocking.
This capacitor is a candidate for avionics power-supply decoupling, downhole instrumentation, or satellite payloads where the ambient swings beyond the commercial or industrial envelope. The molded construction and surface-mount 0805 package keep the profile low for dense boards.
