For a 100 kHz buck converter output, the ripple current rating at 125 mOhm is roughly 1.1 A RMS — enough for a 3-5 A rail with typical ripple ratios. The E case (2917 / 7343 Metric) footprint is a standard across the TPS family, so a layout designed for a 47 µF / 25 V TPS part accepts any E-case TPS value without a board spin. The -55 to 125°C operating range means it holds its capacitance and ESR through the full industrial and military temperature band — no derating cliff at 85°C like some commercial tantalums. ## Active lifecycle — no LTB clock ticking No official successor or cross-reference is listed — the TPS series itself is the current mainstream low-ESR tantalum line from this manufacturer. ## Molded package and surface-mount integration The molded case provides consistent dimensions and mechanical protection during reflow and handling. Tape & Reel or Cut Tape packaging suits both high-volume pick-and-place and prototype kitting. The ±10% tolerance is tight enough for bulk decoupling and energy storage — no need to over-spec to a 5% grade for most rail filtering.","metaTitle":"KYOCERA AVX TPSE476K025R0125 Tantalum Cap, 47 µF, 25 V","metaDescription":"Active-production KYOCERA AVX TPSE476K025R0125 molded tantalum capacitor, 47 µF ±10%, 25 V, 125 mOhm ESR, E case 2917.
