UFW1E223MRD

The UFW1E223MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series designed for audio equipment. It provides large bulk capacitance in a through-hole radial can package to support power-supply smoothing and energy storage in audio applications.

Key characteristics include 22,000 µF capacitance at 25 V, high ripple-current capability at both low and high frequencies, a specified 2,000-hour endurance at 85°C, and an operating range from −40°C to 85°C.

Key Features

• High Capacitance & Voltage — 22,000 µF nominal capacitance rated at 25 V, providing substantial energy storage for audio power supplies and decoupling.
• Dual-Frequency Ripple Handling — Low-frequency ripple current: 4,500 mA (120 Hz); high-frequency ripple current: 5,175 mA (10 kHz), supporting both mains-frequency smoothing and higher-frequency switching ripple.
• Endurance — Rated for 2,000 hours at 85°C under applied voltage, enabling sustained performance in demanding thermal environments.
• Temperature Range — Operates from −40°C to 85°C, suitable for a wide range of ambient conditions encountered in audio equipment.
• Physical & Mounting — Radial lead, can-style package with φ25 × 50 mm dimensions and 12.5 mm lead spacing (no terminal forming for bulk/bag packing), simplifying through-hole assembly.
• Electrical Characteristics — Polarized design with ±20% capacitance tolerance and specified leakage current of 16,500 µA; specified tan δ of 0.58 at 20°C and 120 Hz.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing for amplifier and preamplifier supply rails to maintain stable voltage under dynamic loads.
• Professional Audio Equipment — Use in mixers, powered speakers, and studio gear where large capacitance and reliable ripple handling are required.
• Consumer Audio Systems — Energy reservoir for home receivers and powered subwoofers to support transient response and low-frequency performance.

Unique Advantages

• Substantial Energy Storage: 22,000 µF at 25 V provides significant bulk capacitance for power-supply smoothing and transient support.
• High Ripple Capability: Rated ripple currents at both 120 Hz and 10 kHz let the capacitor address mains-frequency smoothing and higher-frequency switching artifacts.
• Designed for Audio: Part of Nichicon’s UFW series oriented toward audio equipment, combining capacitance, ripple handling, and temperature endurance tailored to audio power applications.
• Long Endurance: 2,000-hour life rating at 85°C under rated voltage supports prolonged operation in thermally stressed environments.
• Through-Hole Convenience: Radial can package with standard lead spacing and bulk/bag packing eases manual assembly and replacement in board-level designs.
