UFW1H222MHD

The UFW1H222MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UFW series, designed for audio equipment applications. It delivers 2200 µF capacitance at a 50 V rating in a compact φ16 × 35.5 mm can with 7.5 mm lead spacing.

Engineered for audio power circuits, the part offers substantial ripple-handling capability across low and high frequencies, defined leakage characteristics, and a 2000-hour endurance at 85°C—making it suitable for sustained operation in consumer and professional audio designs.

Key Features

• Capacitance & Rated Voltage — 2200 µF nominal capacitance with ±20% tolerance at a 50 V rating, suited for bulk energy storage and smoothing in power rails.
• Low Loss — tanδ (DF) of 0.14 measured at 20°C, 120 Hz, indicating controlled dissipation for audio circuits.
• Ripple Current Handling — Low-frequency ripple current 2.09 A (120 Hz) and high-frequency ripple current 2.404 A (10 kHz) for demanding supply-decoupling tasks.
• Leakage Current — Specified leakage current of 3300 µA, documented for predictable standby and bias behavior.
• Endurance & Temperature Range — Rated life of 2000 hours at 85°C; operating range −40°C to +85°C for sustained thermal performance.
• Package & Mounting — Radial lead can (φ16 × 35.5 mm), lead spacing 7.5 mm with 0.5 mm tolerance; available in bulk or bag packing for through-hole assembly.

Typical Applications

• Audio Power Supply Filtering — Provides bulk smoothing and ripple reduction on audio equipment power rails to support stable supply voltages.
• Audio Amplifiers — Suitable for decoupling and reservoir capacitance in amplifier circuits where sustained ripple handling and low dissipation matter.
• Consumer and Professional Audio Electronics — Compact radial can format fits through-hole assemblies in a range of audio products.

Unique Advantages

• High capacitance in a compact can — 2200 µF in a φ16 × 35.5 mm package provides substantial energy storage while conserving board area.
• Broad ripple capability — Specified ripple currents at both 120 Hz and 10 kHz support performance across low and high-frequency components of audio supplies.
• Defined endurance for reliable operation — 2000 hours at 85°C gives designers a clear baseline for lifetime expectations in thermal-stressed environments.
• Measured dissipation for audio fidelity — tanδ = 0.14 at 120 Hz helps manage heating and maintain signal integrity in audio paths.
• Through-hole convenience — Radial leads with 7.5 mm spacing and standard packaging options simplify handling and assembly for OEM production.
