The 900 mOhm ESR sets the ripple-current limit: at 100 kHz, the maximum allowable AC ripple current is roughly 470 mA RMS before self-heating exceeds the 125°C ceiling. For a switching regulator output, this cap handles moderate ripple but not high-frequency, high-ripple bulk banks. ## D-case 2917 footprint — layout fit Package is 2917 (7343 Metric), manufacturer size code D — 7.30 mm x 4.30 mm footprint, 3.10 mm maximum seated height. Surface-mount, supplied on Tape & Reel. The D-case is the standard large-tantalum footprint; the pad layout matches the common 7343-31 pattern used across the TAJ series. ## Temperature range — military-grade operating envelope Rated -55°C to 125°C, which covers the full military/aerospace temperature band. This cap can serve avionics, satellite, downhole instrumentation, or any environment where the ambient swings below -40°C. The 125°C upper limit is the maximum case temperature; derating the applied voltage above 85°C is standard practice per MIL-PRF-55365 guidelines.","metaTitle":"TAJD227K004RNJ – KYOCERA AVX 220 µF 4 V Molded Tantalum","metaDescription":"TAJD227K004RNJ from KYOCERA AVX: 220 µF, 4 V, ±10%, 2917 (7343 Metric) D-case, 900 mOhm ESR, -55°C to 125°C.
