220 µF, 10 V, 100 mOhm ESR — TPS series tantalum
The KYOCERA AVX TPSY227M010R0100V is a molded tantalum capacitor in the TPS series, rated at 220 µF capacitance with a 10 V voltage rating and ±20% tolerance. The 100 mOhm ESR at 100 kHz is the key parameter for ripple handling — lower ESR means less self-heating in high-frequency switching circuits like DC-DC converter outputs or point-of-load filters. Rated for 2000 hours at 125°C, this part suits high-temperature environments such as under-hood automotive or industrial control modules where ambient temperatures push past 105°C.
2917 footprint — board-fit and rework
Surface-mount construction with a molded body; the part is tape-and-reel packaged for automated pick-and-place. The size code Y indicates the case height variant — at 2.00 mm max, it fits under low-profile heatsinks or shrouds.
