UFW1V221MPD

The UFW1V221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UFW series, designed for audio equipment. It delivers 220 µF capacitance at a 35 V rating in a compact φ10 × 12.5 mm can with 5.0 mm lead spacing.

Engineered for applications that require reliable bulk capacitance and ripple handling, this part combines defined low and high-frequency ripple current capability with a -40 °C to 85 °C operating range and 2,000-hour endurance at 85 °C.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated Voltage — 35 V DC rating suitable for common audio equipment rail voltages.
• Low- and High-Frequency Ripple Current — Rated for 370 mA at 120 Hz and 555 mA at 10 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Loss Factor (tan δ) — tan δ = 0.14 (measured at 20 °C, 120 Hz, 35 V), providing defined dissipation characteristics for audio applications.
• Leakage Current — Specified leakage current of 231 µA under rated conditions, supporting predictable bias behavior in circuits.
• Endurance & Temperature Range — Rated for 2,000 hours at 85 °C; operational temperature range from -40 °C to 85 °C.
• Package & Mounting — Radial lead can (φ10 × 12.5 mm) with 5.0 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Polarized — Polarized electrolytic design for DC power applications common in audio equipment.

Typical Applications

• Audio Equipment — Intended for use in audio equipment as specified by the UFW series; provides bulk capacitance and ripple handling for audio power rails and modules.

Unique Advantages

• Audio-focused design — Part of Nichicon's UFW series, explicitly specified "For Audio Equipment," aligning component selection with audio system requirements.
• Defined ripple capability — Rated ripple currents at both 120 Hz and 10 kHz (370 mA and 555 mA respectively) allow designers to account for low- and high-frequency ripple in audio power stages.
• Predictable loss characteristics — tan δ specified at operating measurement conditions (0.14 at 35 V, 120 Hz, 20 °C) aids in thermal and dissipation calculations.
• Compact radial form factor — φ10 × 12.5 mm can with 5.0 mm lead spacing provides a small footprint for through-hole audio assemblies and repair/retrofit projects.
• Long endurance rating — 2,000 hours at 85 °C supports reliability expectations for sustained operation in audio electronics.
• Traceable manufacturer series — Manufactured by Nichicon and offered as part of the UFW family, with mass production availability for consistent supply.
