Bulk decoupling for a 35 V rail — 10 µF with 1.6 Ohm ESR
The TAJC106K035TNJ: 10 µF at 35 V rated — the 1.6 Ohm ESR sets the ripple current limit and self-heating floor. For a 35 V rail with 100 mV ripple, the ripple current stays under 62 mA RMS; above that the internal temperature rise accelerates aging. The ±10% tolerance means the actual capacitance at 25 °C sits between 9 µF and 11 µF — budget the low end for hold-up time calculations. Molded case, 2312 footprint — 6.00 mm x 3.20 mm, 2.80 mm seated height. The size code C is standard for this capacitance-voltage combination; the pick-and-place nozzle profile is the same across the TAJ C-case family.
Temperature grade — -55 to +125 °C, no derating guesswork
Full military temperature range — the part is specified across -55 to +125 °C ambient. In an engine-bay ECU or outdoor radio head that sees 105 °C, the 35 V rating still holds 28 V derated at 80 %; no voltage derating curve needed above 85 °C as with some commercial tantalums.
Design-in safe; no last-time-buy window to track.
