The 35V 1000µF electrolytic capacitor is a polarized aluminum electrolytic capacitor designed for power-supply filtering, voltage smoothing, ripple reduction, energy storage, and DC voltage stabilization. Its relatively high 1000µF capacitance makes it particularly useful in power supplies and circuits with changing current demands.

PCB repair and maintenance

Polarity

This capacitor is polarized, so it must be installed correctly:

+ terminal → positive voltage
− terminal → negative/ground

The negative terminal is normally marked with a stripe on the capacitor body.

Voltage Rating

The 35V rating is its maximum specified working voltage. The applied voltage should remain below this rating, including consideration of possible voltage spikes.

For example, it can commonly be used on 12V and 24V DC systems, provided the actual voltage and transients remain within the capacitor's specifications.
