UFW2A222MRD

The UFW2A222MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, engineered for audio equipment applications. It delivers high capacitance (2200 µF) at a 100 V rating in a compact φ18 × 40 mm can suitable for through‑hole mounting.

Designed for power filtering and energy storage in audio circuits, this polarized capacitor combines a wide operating temperature range (−40°C to 85°C) with defined endurance (2000 hours at 85°C) and measurable electrical characteristics such as low tangent of loss angle and controlled leakage.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C, providing bulk energy storage for power rails in audio systems.
• Low Loss Angle — tanδ of 0.08 (measured at 20°C, 120 Hz) for minimized dissipation and predictable AC performance in signal and power stages.
• Ripple Current Capability — Rated ripple current of 2.4 A at 120 Hz (low frequency) and 2.76 A at 10 kHz (high frequency), supporting filtering and smoothing under varying ripple conditions.
• Controlled Leakage — Specified leakage current of 660 µA for predictable standby and bias behavior after voltage application.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C and operating from −40°C to 85°C, enabling reliable operation across common environmental conditions for audio equipment.
• Radial Can Package — φ18 × 40 mm aluminum can with 10 mm lead spacing (±0.5 mm) for easy through‑hole mounting; available in bulk or bag packing (no terminal forming).

Typical Applications

• Audio Equipment — Bulk energy storage and supply smoothing in amplifiers, mixers, and other audio power modules within the UFW series' target market.
• Power Supply Filtering — DC rail smoothing and decoupling for medium‑voltage power supplies where 100 V rating and high capacitance are required.
• Energy Reservoirs — Local energy buffering in systems that require large capacitance in a through‑hole radial form factor.

Unique Advantages

• High Capacitance at High Voltage — 2200 µF at 100 V provides significant energy storage in a 18 mm diameter can, reducing the need for multiple smaller capacitors.
• Engineered for Audio — Part of Nichicon’s UFW series, positioned for audio applications where the combination of capacitance, voltage rating, and loss characteristics matter.
• Measurable Ripple Performance — Specified ripple current ratings at 120 Hz and 10 kHz enable predictable thermal and AC behavior during design validation.
• Robust Endurance — 2000 hours at 85°C specification gives a quantifiable lifetime target for thermal stress planning and reliability assessments.
• Installation‑Friendly Package — Standard radial lead spacing (10 mm) and common can dimensions simplify retrofits and new designs using through‑hole assembly.
