Würth Elektronik · Aluminum electrolytic (radial) · Radial THT, 6.3 x 11.0 mm (P=2.5 mm)

100 µF, 25 V polarized aluminum electrolytic capacitor in a radial through-hole 6.3 mm x 11 mm can (2.5 mm lead pitch), from Würth's WCAP-ATUL series. Rated 105 °C with 5000 h load life, 350 mA ripple current at 100 kHz, and 0.25 ohm impedance. The default bulk / reservoir capacitor for power-supply smoothing and local energy storage. Polarized: observe the + and - terminals.

Pinout

Pin	Name	Type	Function
1	+	passive	Positive (anode) terminal of the polarized aluminum electrolytic capacitor. Must be biased positive relative to the negative terminal; reverse voltage can damage or destroy the capacitor. Rated working voltage 25 V DC.
2	-	passive	Negative (cathode) terminal of the polarized aluminum electrolytic capacitor. Identified by the shorter lead wire and by a color band with minus signs on the sleeve.
