UFW1E222MHD

The UFW1E222MHD is a radial-lead aluminum electrolytic capacitor offering 2.2 mF (2200 µF) capacitance at a 25 V rating in a compact φ12.5 × 25 mm can. It is part of Nichicon's UFW series, designed for audio equipment and related electronics where reliable bulk energy storage and ripple handling are required.

With a temperature rating from −40 °C to +85 °C and a 2000-hour endurance at 85 °C, this polarized capacitor targets power-smoothing, decoupling, and filtering roles in through-hole assemblies that demand sustained ripple tolerance and proven lifetime performance.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 25 V and tolerance ±20% (measured at 20 °C, 120 Hz).
• Dissipation Factor — tan δ of 0.18 (measured at 20 °C, 120 Hz), specified for quality audio-focused performance.
• Ripple Current Capability — Low-frequency ripple current 1.55 A at 120 Hz and high-frequency ripple current 1.782 A at 10 kHz, suitable for power-supply smoothing and decoupling in audio circuits.
• Leakage Current — Specified leakage current of 1650 µA, providing predictable standby characteristics after voltage application.
• Endurance & Temperature — Rated for 2000 hours at 85 °C, with an operating temperature range from −40 °C to +85 °C.
• Package & Mounting — Radial lead, polarized aluminum can with φ12.5 mm diameter and 25 mm length, 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Production Status — Mass production availability for consistent sourcing and BOM planning.

Typical Applications

• Audio Equipment Power Supplies — Bulk energy storage and smoothing for analog and digital audio circuits where stable supply rails are important.
• Amplifier Decoupling — Local supply decoupling in amplifier stages to maintain transient response and reduce supply ripple effects.
• Consumer Electronics — Through-hole power-filtering roles in PCBs and assemblies requiring reliable polarized capacitors with proven lifetime characteristics.

Unique Advantages
