T491B226M006AT

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

T491B226M006AT 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 ANODE (+) passive Positive polar terminal, identified on the case by the polarity stripe and beveled edge, and must not be connected with reversed polarity because the capacitor may be permanently damaged or destroyed.
2 CATHODE (-) passive Negative polar terminal (leadframe marked −Cathode), which may see only the transient reverse voltage permitted by the datasheet (15% of rated voltage at 25°C, 5% at 85°C, 1% at 125°C) and must not be operated continuously in reverse.
