150 µF bulk decoupling for 6.3 V rails
The TPSC157K006R0250 is a molded tantalum capacitor from the TPS series, rated 150 µF at 6.3 V with a 250 mOhm ESR.
The part can sit in an avionics power supply, a downhole sensor module, or an outdoor telecom base station where the ambient cycles between a cold night and a hot day. The molded case and surface-mount package (2312 / 6032 Metric) mean it reflows with standard solder profiles and shares a footprint with other C-size tantalums — no special handling beyond the usual moisture sensitivity level for molded parts.
