68 µF, 6.3 V molded tantalum — TPS series
The KYOCERA AVX TPSW686K006R0125 is a molded tantalum capacitor in the TPS series, offering 68 µF capacitance at a 6.3 V rated voltage with ±10% tolerance. The 125 mOhm ESR at 6.3 V means this cap handles ripple current without excessive self-heating — a key parameter for decoupling bulk power rails where the ripple current can push a higher-ESR part past its thermal limit.
Temperature range and board fit
Rated for -55°C to 125°C operation, the TPSW686K006R0125 spans the full industrial temperature envelope — suitable for outdoor telecom, motor-drive control boards, and under-hood electronics where the ambient cycles between cold start and hot soak.
