UFW2A221MHD

The UFW2A221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, specified at 220 µF with a 100 V rated voltage. It is built for audio equipment applications and offers a compact φ12.5 × 25 mm can with 5 mm lead spacing.

Designed for power decoupling and energy storage in audio equipment, the part combines high-voltage capability with defined ripple performance and endurance characteristics, delivering a reliable solution for medium-voltage audio circuits operating across a broad temperature range.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable filtering and energy storage.
• High Voltage Rating — 100 V rated voltage suitable for higher-voltage audio and related circuitry within the UFW series range.
• Ripple Current Performance — Rated for 600 mA at 120 Hz (low frequency) and 900 mA at 10 kHz (high frequency), supporting both mains-frequency and higher-frequency ripple conditions.
• Leakage Current — Specified leakage current of 660 µA for low standby loss under rated voltage conditions.
• Endurance — 2000 hours life at 85°C with performance criteria restored after recovery to 20°C, providing defined long-term stability under rated conditions.
• Mechanical / Mounting — Radial lead, can-style package (φ12.5 × 25 mm) with 5 mm lead spacing for through-hole PCB assembly or hand-soldered installations.
• Operating Temperature — Rated −40°C to +85°C to cover typical ambient ranges encountered in audio equipment and related electronics.

Typical Applications

• Audio Equipment — Intended for use in audio devices where stable bulk capacitance and defined ripple handling are required.
• Power Supply Filtering — Suitable for smoothing and decoupling in medium-voltage sections of audio power supplies and related circuits.
• Amplifier Systems — Applicable where a combination of 100 V rating and 220 µF capacitance supports signal-chain and power-stage stability in audio applications.

Unique Advantages

• High Voltage Capability: 100 V rating allows use in higher-voltage audio and power circuits without requiring series stacking.
• Defined Ripple Handling: Separate ripple current ratings for 120 Hz and 10 kHz (600 mA and 900 mA respectively) provide clear guidance for both low- and high-frequency ripple environments.
• Longevity Under Load: 2000 hours endurance at 85°C gives predictable life characteristics for equipment expected to operate at elevated temperatures.
• Compact Radial Form: φ12.5 × 25 mm can with 5 mm lead spacing offers a compact through-hole footprint for retrofits and PCB designs.
• Low Leakage: 660 µA leakage current minimizes quiescent losses and helps preserve DC stability in audio circuits.
