The TPSW107K010R0150: The 150 mOhm ESR (equivalent series resistance) is the number that governs ripple current handling and self-heating. A lower ESR means the capacitor can absorb more AC ripple before the internal temperature rise becomes a concern; at 150 mOhm this part sits in the mid-range for a 100 µF tantalum, balancing ripple capability against the inrush current the upstream regulator sees at startup.
Package and temperature — board-fit and environmental envelope
The manufacturer size code W maps to this footprint — confirm the land pattern matches the 6.0 x 3.2 mm pad geometry before committing the PCB layout. Rated for -55°C to 125°C, this capacitor operates across the full industrial temperature range. That covers outdoor base-station electronics, engine-bay modules, and cold-chain storage equipment without a separate temperature-grade variant.
Active lifecycle — no end-of-life pressure on this BOM line
The TPS series is a standard molded tantalum line; the W case code (2312) is a common footprint shared across multiple manufacturers, so second-source options exist if the BOM needs a hedge.
