This directly limits the ripple current the capacitor can handle without exceeding its internal temperature rise — for a 25 V part in a buck converter output filter, the ripple current should be kept below ~500 mA RMS to avoid self-heating that accelerates failure. ## Temperature range and capacitance stability Tantalum MnO₂ capacitors lose capacitance at low temperature — at -55°C the capacitance can drop to 60-70% of the 25°C value, and the ESR rises by a factor of 3-5x. At 125°C, the leakage current increases and the voltage derating should be increased to 60% of rated voltage (15 V max) for long-term reliability. It remains in the KYOCERA AVX production portfolio and is sourced through authorized distribution. ## Package and footprint — 2917 (7343 Metric), Y case code The Y code indicates the 7343-20 profile — 2.0 mm max height, compatible with the common 7343-20 footprint.","metaTitle":"KYOCERA AVX TAJY156M025RNJ Tantalum Capacitor, 15 µF, 25 V","metaDescription":"KYOCERA AVX TAJ series molded tantalum capacitor, 15 µF, 25 V, ±20%, 1 Ohm ESR, 2917 case.
