UFW1J221MPD

The UFW1J221MPD is an aluminum electrolytic capacitor from Nichicon’s UFW series, supplied in a radial lead, can-style package. It delivers 220 µF nominal capacitance at a 63 V rating with a ±20% tolerance, designed specifically for audio equipment applications requiring bulk energy storage and power-rail conditioning.

Key performance attributes include specified low- and high-frequency ripple current ratings, defined leakage current, and a 2000-hour endurance rating at 85°C, making this part suitable for audio power supplies and related circuits where stable performance over time and temperature is required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance for predictable capacitance margin in design.
• Ripple Current Capability — Rated for 470 mA at 120 Hz (low frequency) and 705 mA at 10 kHz (high frequency), supporting both power-supply smoothing and higher-frequency ripple conditions.
• Leakage Current — Specified leakage current of approximately 415.8 µA for predictable quiescent current behavior under rated conditions.
• Endurance & Temperature — 2000 hours rated life at 85°C and an operating temperature range of −40℃ to +85℃, supporting long-term deployment in audio equipment environments.
• Electrical Loss (tan δ) — Series-level specification includes a maximum tan δ of 0.10 at 63 V (measured at 120 Hz, 20℃), aiding assessment of dissipation in AC conditions.
• Package & Mounting — Radial lead (can) package with φ10 × 16 mm body size, 5 mm lead spacing and polarized construction for through-hole PCBs and hand/robotic insertion processes.

Typical Applications

• Audio Power Supplies — Bulk smoothing and filtering on amplifier and preamplifier power rails to reduce hum and stabilize supply voltages.
• Amplifier Systems — Reservoir and decoupling capacitor for discrete and integrated audio amplifier stages where 63 V rating gives additional headroom.
• Audio Equipment Boards — General-purpose DC filtering and decoupling on PCBs for mixers, effects units, and consumer/pro audio devices.

Unique Advantages

• High Voltage Headroom: 63 V rating provides margin for designs that require elevated rail voltages or transient tolerance.
• Measured Ripple Performance: Specified ripple current values at both 120 Hz and 10 kHz allow designers to size capacitors based on the dominant ripple frequencies in audio power stages.
• Long Endurance at Elevated Temperature: 2000 h life at 85℃ supports reliable operation in thermally demanding enclosures and prolonged use.
• Compact Radial Can: φ10 × 16 mm footprint with 5 mm lead spacing simplifies placement on through-hole PCBs while conserving board area.
• Known Dissipation Characteristics: Series tan δ specification (0.10 at 63 V) and specified leakage current help predict AC loss and standby currents in system models.
