UFW1C223MRD

The UFW1C223MRD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment. It provides very high bulk capacitance (22,000 µF) at a 16 V rating in a radial can package intended for through‑hole mounting.

Engineered for power‑rail energy storage and filtering in audio applications, this unit combines large capacitance, specified ripple current capability, and a broad operating temperature range to support stable supply performance in consumer and pro audio designs.

Key Features

• High Capacitance — 22,000 µF (22 mF) nominal capacitance for substantial energy storage and smoothing in low‑voltage audio power rails.
• 16 V Rated Voltage — Suitable for 16 V power rails where large bulk capacitance is required.
• Radial Lead Can — φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm), designed for radial through‑hole mounting.
• Operating Temperature Range — Specified for −40 °C to +85 °C to accommodate common ambient conditions in audio equipment.
• Endurance — Rated life of 2000 hours at 85 °C with specified limits for capacitance change, dissipation factor, and leakage current after the endurance test.
• Dissipation Factor (tan δ) — Specified tan δ of 0.22 measured at 20 °C, 120 Hz for this part.
• Leakage Current — Specified leakage current of 1056 µA (as provided for this part).
• Ripple Current Capability — Provided ripple current values include 1.25 A (low frequency) and 2.00 A (high frequency); series datasheet also lists frequency‑rated values of 4.2 A at 120 Hz and 4.83 A at 10 kHz for higher‑capacitance parts under the UFW series guidance.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible assembly handling.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing on low‑voltage rails in amplifiers, preamps and powered mixers where sustained capacitance is required.
• Power Filtering for Audio Systems — Decoupling and ripple suppression for digital/analog supply sections in audio equipment.
• Signal‑Chain Support — Reservoir capacitance for circuits that require stable local supply during transient audio peaks.

Unique Advantages

• Large Stored Energy in a Radial Can — 22,000 µF capacitance delivers significant reservoir capacity while using a φ12.5 × 20 mm can footprint for through‑hole layouts.
• Audio‑Focused Series Design — Part of the UFW family, specified and intended for audio equipment applications.
• Temperature and Endurance Specifications — Rated −40 °C to +85 °C with 2000 hours endurance at 85 °C for predictable long‑term behavior under thermal stress.
• Measured Dissipation and Leakage Parameters — Provided tan δ and leakage current values support engineering evaluation for noise and power‑loss budgets.
• Flexible Packaging for Assembly — Bulk or bag packing options simplify procurement and handling for manual or automated through‑hole assembly processes.
