150 µF on a 10 V rail — what the ESR tells you
That ESR number is the one that matters most for a bulk decoupling or output filter cap: at 100 kHz ripple, 900 mOhm means about 150 mA of ripple current before self-heating starts to eat into the 125°C ceiling. If your rail is switching at 500 kHz, the ESR limit is the same — the cap doesn't care about frequency until the dielectric losses kick in above 1 MHz.
Full temp range — no derating guesswork
That means it fits in an avionics power supply that sees -40°C on the tarmac and 105°C in the equipment bay — no need to derate the voltage or capacitance for the cold end. The molded case keeps the mechanical integrity through thermal cycling; the 2312 footprint is a standard size that matches most pick-and-place feeders.
Active — no last-time-buy clock ticking
Listed as Active from KYOCERA AVX. No EOL notice, no NRND flag — this part is still a first-choice BOM line. The TAJ series is a broad, long-running family, so second-source equivalents from other manufacturers (same case, same ratings) are available if you need to dual-source. No pin-compatible direct replacement from AVX itself; the TAJ series is the current production line.
