Bulk decoupling or hold-up — the ESR tells the story
The TPSV227K016R0050: For a hold-up capacitor bridging a 100 ms power dip at 1 A, the voltage drop across the ESR is 50 mV — negligible in most digital circuits.
Temperature range and board fit
Rated -55°C to 125°C, this part covers industrial and automotive ambient conditions without derating at the high end — though tantalum capacitors do lose capacitance at low temperature; at -55°C expect about 80% of the 220 µF nominal. The 7.30 mm x 6.10 mm footprint with a 3.75 mm seated height fits standard 2924 pads; the V case code matches the standard land pattern for this size. Surface-mount assembly with standard reflow profiles works; the molded body is compatible with both lead-free and tin-lead solders.
Active lifecycle — no end-of-life pressure
Listed as Active by KYOCERA AVX, so there is no last-time-buy clock or obsolescence risk on this order code. The TPS series is a mature, widely used molded tantalum family with multiple distributors carrying stock. For BOM planning, the ±10% tolerance is standard — no special binning or extended lead times expected for this grade.
