For a 3.3 V rail decoupling a 100 mA transient, the voltage drop across the ESR is 0.37 V, which is within the typical regulator headroom but eats into the noise margin. The 3.7 Ohm ESR is specified at 25 °C; at 125 °C the ESR roughly doubles, so the ripple current rating must be derated by the square root of the temperature factor. A 20 % voltage derating (20 V max applied on a 25 V part) is standard practice for tantalum capacitors at the high end of the temperature range to avoid field-failure from surge current. ## Active lifecycle — no LTB window to plan around ## 1206 case — the board-space trade-off The 1206 (3216 Metric) case measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm. The land pattern follows the standard IPC-7351 footprint for 1206 chip capacitors — no via-in-pad required, but the pad width should match the terminal width to avoid solder bridging. The molded body is polarity-sensitive; the anode terminal is marked with a stripe on the top face.","metaTitle":"TAJA335M025RNJ KYOCERA AVX 3.3 µF 25 V Molded Tantalum","metaDescription":"TAJA335M025RNJ — KYOCERA AVX TAJ series, 3.3 µF ±20 %, 25 V, 3.7 Ohm ESR, -55 to 125 °C, 1206 case.
