220 µF bulk decoupling for 2.5 V rails
The TPSB227K002R0200 is a molded tantalum capacitor from KYOCERA AVX's TPS series, rated 220 µF at 2.5 V with a 200 mOhm ESR. This combination suits it for bulk decoupling on low-voltage processor or FPGA core rails where the 200 mOhm ESR keeps ripple voltage within the supply tolerance without excessive self-heating.
Military temperature range and molded construction
The molded case provides mechanical stability and moisture resistance, supporting the wide temperature range without the cracking risk sometimes seen in conformally-coated tantalum parts.
Footprint and sourcing posture
The 1411 (3528 Metric) / 1210 case size accepts standard land patterns for either footprint, simplifying PCB layout if the BOM already uses one of the two sizes.
