UFW2A220MED

The UFW2A220MED is an aluminum electrolytic, radial-lead capacitor from Nichicon's UFW series designed for audio applications. It combines a 22 µF capacitance with a 100 V rating in a compact φ6.3 × 11 mm radial can, delivering low loss and reliable performance for audio circuitry.

Key value comes from its low dissipation factor (tan δ = 0.08 at 20°C, 120 Hz), defined ripple-current capability at both low and high frequencies, and a 2000-hour endurance rating at 85°C—attributes relevant to designs where stable AC performance and long-term reliability matter.

Key Features

• Capacitance & Tolerance — 22 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable filtering and coupling behavior.
• High Voltage Rating — Rated for 100 V to support higher-voltage audio stages and power rails.
• Low Dissipation Factor — tan δ of 0.08 (max) measured at 20°C, 120 Hz, supporting low-loss performance in audio signal and power paths.
• Ripple Current Capability — Rated ripple current of 120 mA at 120 Hz and 240 mA at 10 kHz to handle both low- and high-frequency ripple components.
• Leakage Current — Typical leakage current up to 66 µA, consistent with the rated capacitance and voltage.
• Endurance & Temperature Range — 2000 hours life at 85°C and an operating range of −40°C to +85°C for robust performance in controlled-temperature audio equipment.
• Package & Mounting — Radial lead, can-style package (φ6.3 × 11 mm) with 2.5 mm lead spacing; supplied in bulk/bag packing, suitable for through-hole assembly.
• Polarized Design — Polarized aluminum electrolytic capacitor for use where polarity is observed in circuit design.

Typical Applications

• Audio Equipment — Intended for audio circuitry within consumer and professional audio products where reliable DC-blocking, decoupling, or smoothing is required.
• Power Supply Circuits — Suitable for power-rail filtering in audio power supplies operating up to 100 V.
• Signal Coupling and Decoupling — Useful in audio signal paths and decoupling networks where low dissipation and defined ripple handling improve performance.

Unique Advantages

• Low Loss at Audio Frequencies — Specified tan δ = 0.08 at 120 Hz reduces energy dissipation, supporting clearer signal paths in audio applications.
• Defined Ripple Handling Across Frequencies — Separate ripple current ratings for 120 Hz and 10 kHz (120 mA / 240 mA) provide designers with quantifiable AC performance for both mains-derived and high-frequency ripple.
• Compact Through-Hole Form Factor — φ6.3 × 11 mm radial can with 2.5 mm lead spacing delivers a small footprint for tight PCB layouts while retaining through-hole mounting robustness.
• High Voltage Margin — 100 V rating permits use in higher-voltage audio stages and power rails without up-rating multiple lower-voltage parts.
• Long Life at Elevated Temperature — 2000-hour endurance at 85°C supports designs intended for continuous operation in controlled thermal environments.
