100 µF, 20 V molded tantalum for high-temp BOMs
Its 400 mOhm ESR at 100 kHz sets the ripple current ceiling — for a 500 mA ripple, the self-heating is about 100 mW, well within the package's thermal budget at 125°C. The molded construction gives consistent mechanical dimensions for pick-and-place.
Sourcing and compliance note
The part is RoHS compliant per the manufacturer's standard declaration. No equivalent or direct cross-reference is listed by KYOCERA AVX; the TAJ series includes multiple voltage/capacitance variants in the same case size, but each order code is unique to its rating.
