Capacitor Rebel URZ3134 25 µF 450 V – Electrolytic Power Capacitor

Rebel URZ3134 is a 25 µF, 450 V electrolytic power capacitor intended for use in power supplies, motor start/run circuits and industrial electronics. The component provides 25 microfarads of capacitance at a rated voltage of 450 volts and is designed to stabilize DC bus voltage, smooth ripple, and absorb transient currents in repair, maintenance and custom assembly tasks where a compact high‑voltage electrolytic capacitor is required.

Advantages

The capacitor offers a combination of compact size and high voltage rating suitable for confined enclosures. Its electrolytic design delivers relatively high capacitance per volume, enabling effective smoothing of power supply ripple and support for short-duration load surges. The part is compatible with common axial and radial mounting arrangements used in power electronics repair and retrofit work, providing a straightforward replacement option for aging or failed capacitors in similar circuits.

Suitable for

• Power supply ripple smoothing and DC bus stabilization
• Motor start/run and auxiliary motor circuits
• Industrial control and power electronics repair
• Custom assemblies and prototyping requiring compact high-voltage capacitance

Key specifications

• Capacitance: 25 µF
• Rated voltage: 450 V DC
• Capacitor type: Electrolytic power capacitor
• Application environment: Power electronics, motor circuits, industrial equipment
• Typical functions: Voltage stabilization, ripple smoothing, transient current support

How to use

Install the capacitor following the circuit designer’s polarity and voltage guidelines. Ensure the capacitor’s rated voltage of 450 V exceeds the maximum DC stress expected in the circuit and observe correct polarity when connecting to DC rails. Secure the component mechanically within the enclosure to prevent vibration or movement. When replacing an existing capacitor, match capacitance and voltage ratings and verify lead spacing and mounting orientation for compatibility.

Usage recommendations

Before installation, discharge existing capacitors in the circuit and confirm power is removed. Operate the capacitor within its rated temperature and voltage limits; avoid prolonged exposure to voltages near or above the rating. For long-term reliability, allow adequate ventilation or heat dissipation in high-temperature environments and follow safety procedures when working on high-voltage equipment.
