T491A225K035AT

KEMET · Tantalum Capacitors · CASE-A-3216-18(mm)

T491A225K035AT from KEMET, in a CASE-A-3216-18(mm). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 + passive Anode (+) terminal, marked on the body by a polarity stripe and bevelled edge; it must not be reverse-biased beyond 15% of rated voltage at 25°C, 5% at 85°C and 1% at 125°C (transient only).
2 - passive Cathode (-) terminal at the end opposite the polarity stripe; for the 35 VDC rated T491A225K035AT, the recommended maximum application voltage is 50% of VR from -55°C to 85°C and 33% of VR from 85°C to 125°C.
