UFW1C221MED

The UFW1C221MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series designed for audio equipment and related circuits. It provides 220 µF capacitance at a 16 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

This part offers a balance of ripple handling, compact size and endurance: rated ripple currents of 250 mA (120 Hz) and 375 mA (10 kHz), a leakage current of 105.6 µA, and an endurance rating of 2000 hours at 85 °C. Note: this specific part is listed as End Of Life.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 16 V and ±20% tolerance at 120 Hz, 20 °C.
• Ripple Performance — Rated ripple current of 250 mA at 120 Hz (low frequency) and 375 mA at 10 kHz (high frequency), supporting power-filtering tasks in audio circuits.
• Low Leakage — Specified leakage current of 105.6 µA, suitable where low standby leakage is required.
• Endurance — 2000 hours life at 85 °C with specified limits on capacitance change, tan δ and leakage current after test conditions.
• Package & Mounting — Radial lead, can-style package (φ6.3 × 11 mm), 2.5 mm lead spacing; supplied Bulk (No Terminal Forming) / Bag packing.
• Operating Range — Rated to operate from −40 °C to +85 °C, matching the UFW series category temperature range.
• Polarized Device — Polarized electrolytic construction for correct orientation in DC circuits.

Typical Applications

• Audio equipment — Intended for audio-related circuits where 220 µF, 16 V electrolytic capacitance is required.
• Through‑hole PCB assemblies — Radial lead form with 2.5 mm lead spacing provides straightforward through‑hole placement and soldering.
• Prototype and board-level replacement — Compact φ6.3 × 11 mm can size fits space‑constrained boards and common replacement footprints.

Unique Advantages

• Targeted audio-series design: Built to the UFW series specifications for audio equipment, providing appropriate electrical characteristics for audio applications.
• Dual-frequency ripple capability: Explicit ripple ratings at 120 Hz and 10 kHz provide measurable performance for both low‑ and high‑frequency power filtering.
• Compact radial can: Small φ6.3 × 11 mm footprint with 2.5 mm lead spacing reduces board area while retaining sufficient capacitance.
• Measured endurance: 2000 hours at 85 °C gives a documented life rating for thermal endurance planning.
• Low leakage current: Specified 105.6 µA leakage supports designs where leakage budgets are constrained.

Why Choose UFW1C221MED?

UFW1C221MED is positioned for designers who need a compact, radial aluminum electrolytic capacitor with clear, measurable performance in audio-focused and through‑hole PCB applications. Its specified ripple current ratings, low leakage, and 2000‑hour endurance at 85 °C make it suitable for board-level power filtering and decoupling where these characteristics are required.

Because this part is listed as End Of Life, it remains useful for replacement, legacy designs, and situations where the documented dimensions and electrical specifications match existing assemblies. Evaluate inventory and lifecycle needs accordingly when specifying this component.
