0.47 µF, 25 V, 7 Ohm ESR — molded tantalum for tight spots
The TPSA474M025R7000: This is a 0.47 µF molded tantalum capacitor in the TPS series from KYOCERA AVX, rated at 25 V with ±20% tolerance. The 7 Ohm ESR is the number that drives self-heating and ripple current handling — at this value, it is suited for decoupling and filtering where the AC ripple stays modest. Manufacturer size code A matches the 0.126" x 0.063" body.
That means no last-time-buy deadline, no forced redesign — this part is still in regular production and can be ordered against a BOM line without an obsolescence clock.
The molded case handles the thermal cycling without cracking — a common failure mode in wet tantalums.
