22 µF bulk decoupling with 800 mOhm ESR
The TPST226M010R0800 is a 22 µF molded tantalum capacitor in the TPS series from KYOCERA AVX, rated at 10 V with an equivalent series resistance of 800 mOhm. The 1411 (3528 Metric) / 1210 case size fits standard low-profile pad layouts, seated at 1.20 mm max. This ESR value is the key thermal parameter — at 800 mOhm the self-heating from ripple current stays manageable for typical decoupling duty, but the ripple current rating should be derated if the application drives high AC content through the part.
Temperature range and derating margin
Rated for -55°C to 125°C operating temperature, the TPST226M010R0800 covers industrial and automotive underhood environments. The ±20% tolerance is standard for this class; capacitance at the low end still provides adequate charge storage for bulk bypass on most digital loads.
