220 µF bulk cap for tight boards
The TAJY227M004RNJ: 220 µF at 4 V in a 2917 (7343 Metric) case — one can of this TAJ series part replaces two 100 µF in parallel on a power rail, freeing board area for other routing. The 300 mOhm ESR is moderate for this capacitance; it keeps ripple-current self-heating manageable in a 2 A step-down converter output filter.
This cap sits on a satellite power bus that sees -40°C on the dark side and 85°C in direct sunlight, with margin at both ends. The molded case (Type Molded) handles the thermal cycling without cracking the anode connection — a common failure in conformally-coated boards that go through reflow multiple times.
Active product status — KYOCERA AVX is still running the TAJ series, so no last-time-buy deadline on this order code.
