T491B107K010AT

KEMET · Tantalum Capacitors · CASE-B-3528-21(mm)

T491B107K010AT from KEMET, in a CASE-B-3528-21(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 by the polarity stripe and bevel on the case, rated 10 VDC for T491B107K010AT with permissible transient reverse voltage of 15% of rated voltage at 25°C, 5% at 85°C and 1% at 125°C.
2 - passive Cathode (-) terminal at the end opposite the polarity stripe, connected to the negative side of the circuit since the part must not be operated continuously in reverse.
