UFW1H221MPD

The UFW1H221MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UFW series, engineered for audio equipment and related electronic systems. It delivers 220 µF capacitance at a 50 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing, balancing bulk capacitance with a small footprint.

Key value propositions include frequency-dependent ripple handling (rated ripple current at both low and high frequencies), a wide operating temperature range from −40°C to 85°C, and a 2000-hour endurance rating at 85°C for stable performance in audio and power-decoupling roles.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Package & Mounting: Radial lead, aluminum can package (φ10 × 12.5 mm) with 5 mm lead spacing for through-hole designs and straightforward PCB placement.
• Ripple Current Performance: Rated ripple current of 410 mA at 120 Hz and 615 mA at 10 kHz, reflecting the UFW series frequency coefficients for 100–470 µF (120 Hz = 1.00, 10 kHz or more = 1.50).
• Leakage & Loss: Specified leakage current of 330 µA and a tan δ (loss tangent) max of 0.12 at 50 V (measured at 120 Hz, 20°C).
• Temperature & Endurance: Operating range −40°C to +85°C with endurance of 2000 hours at 85°C; after the endurance test the part meets specified limits for capacitance change, tan δ, and leakage current per the series specification.
• Audio-Focused Series: Part of the UFW series, identified in the datasheet as “Standard, For Audio Equipment,” aligning the component’s characteristics with audio power and decoupling needs.

Typical Applications

• Audio amplifiers: Bulk filtering and power-supply smoothing where 220 µF and a 50 V rating support stable rail decoupling for amplifier stages.
• Consumer audio equipment: Power decoupling and reservoir capacitance in receivers, powered speakers, and audio interfaces where compact can size and rated ripple current are required.
• Signal and power decoupling: Local energy storage and ripple suppression for audio front-ends and power circuits operating within −40°C to 85°C service conditions.

Unique Advantages

• Audio-oriented design: Specified as part of Nichicon’s UFW audio series, providing characteristics aligned with audio equipment requirements.
• High-frequency ripple capability: Rated ripple current rises with frequency (1.50× at 10 kHz for this capacitance range), enabling improved performance for high-frequency switching or audio-band ripple components.
• Compact radial can: φ10 × 12.5 mm package with 5 mm lead spacing offers a small footprint for through-hole assemblies without sacrificing capacitance.
• Long endurance at elevated temperature: 2000 hours at 85°C endurance rating supports reliable operation in sustained thermal conditions.
• Clear electrical specifications: Defined leakage current (330 µA), tan δ limit (0.12 at 50 V), and ±20% tolerance enable predictable behavior in design and BOM selection.

Why Choose UFW1H221MPD?

The UFW1H221MPD positions itself as a practical, audio-focused electrolytic capacitor offering a blend of bulk capacitance, compact radial packaging, and defined ripple performance across frequency.
