330 µF, 25V (Aluminium Electrolytic)

330 µF, 25V (Aluminium Electrolytic), Through hole

Identification and Orientation
The Long Lead Rule: The positive lead (anode) is visibly longer than the negative lead on through-hole models.
The Stripe Indicator: The capacitor body features a printed stripe (usually containing a minus symbol -) marking the negative lead.

A 330μF electrolytic capacitor is a polarized electronic component used to store electrical energy and stabilize circuits. It is primarily used for power supply filtering, smoothing out voltage fluctuations, decoupling ICs, and voltage regulation in audio amplifiers, TVs, computers, and electronic hobby projects.

The specific voltage rating determines where it is used:
Low Voltage (10V – 35V): Commonly used for smoothing DC outputs on 5V and 12V logic circuits, microcontrollers, and low-voltage audio boards. Low-ESR variants are also highly favored in drone electronics (FPV quadcopters) to eliminate video noise and prevent electrical desyncs.
Medium Voltage (50V – 100V): Found in medium-power audio amplifiers, automotive electronics, and industrial control systems.
High Voltage (200V – 450V): Utilized in the primary stages of switch-mode power supplies (SMPS), televisions, inverters, and domestic appliances.
