How It Works

When connected to a DC power supply, the capacitor charges and stores electrical energy. When the supply voltage drops or the circuit demands additional current, the capacitor can discharge some of its stored energy. In a rectifier power supply, this action helps convert pulsating DC into a smoother DC voltage.

The 3300µF value provides significantly more filtering capacity than smaller capacitors such as 100µF or 470µF, making it useful where larger current fluctuations or ripple need to be controlled. Specifications & Features

Capacitance (3300µF): Provides a large storage capacity to smooth out voltage ripples in DC power lines.
Voltage Rating (35V): The maximum safe DC voltage the capacitor can withstand. In practice, your circuit operating voltage should ideally be 24V or lower to maintain a safe 30%+ buffer.
Common Dimensions:
- Radial Through-Hole (Standard): Usually measures 16x25mm or 18x35mm with standard lead spacing.
- Snap-In (Heavy Duty): Usually measures around 22x25mm or 20x30mm for larger power supply units.
Temperature Rating: Typically rated up to 105°C for long-term thermal stability.
Polarity: This is a polarized component. The negative terminal is strictly marked with a stripe/minus sign on the casing and has a shorter lead. Backward installation can cause it to burst.
