UFW1A221MED

The UFW1A221MED is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio equipment. It provides 220 µF capacitance at a 10 V rating in a compact φ6.3×11 mm can, delivering polarization, bulk energy storage and AC ripple handling for audio circuits and related electronics.

Key electrical characteristics include a capacitance tolerance of ±20%, a measured tanδ of 0.24 (20 °C, 120 Hz, 10 V), low leakage current, and rated endurance of 2000 hours at 85 °C, enabling reliable performance across the specified operating range.

Key Features

• Capacitance & tolerance — 220 µF nominal with ±20% tolerance, providing predictable bulk filtering and decoupling for low‑voltage audio systems.
• Rated voltage & polarization — 10 V rated, polarized construction suitable for DC bias applications common in audio circuitry.
• Loss characteristics — tanδ (DF) 0.24 measured at 20 °C, 120 Hz and 10 V, useful for assessing dissipation in audio signal and power stages.
• Ripple current capability — Low‑frequency ripple current 230 mA at 120 Hz and high‑frequency ripple current 345 mA at 10 kHz, supporting both supply smoothing and higher‑frequency decoupling tasks.
• Leakage current — Specified leakage current of 66 µA, enabling low‑offset operation in sensitive circuits.
• Mechanical & mounting — Radial lead, can package (φ6.3×11 mm) with 2.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through‑hole assembly.
• Environmental & endurance — Operating range −40 °C to +85 °C with a rated life of 2000 hours at 85 °C, matched to long‑term service in temperature‑controlled audio equipment environments.

Typical Applications

• Audio equipment — Bulk filtering, supply decoupling and energy storage in audio systems where compact, polarized electrolytics are required.
• Audio equipment — High‑frequency decoupling in audio power stages supported by a 345 mA ripple capability at 10 kHz.
• Audio equipment — Low‑leakage applications and coupling/decoupling tasks that benefit from the specified 66 µA leakage current and ±20% capacitance tolerance.

Unique Advantages

• Compact radial can — φ6.3×11 mm footprint and radial lead format provide a small, easy‑to‑place through‑hole option for tight PCBs and legacy layouts.
• Designed for audio use — Part of the UFW series specified for audio equipment, aligning electrical characteristics with common audio design needs.
• Measurable ripple performance — Explicit low‑ and high‑frequency ripple current ratings (230 mA @120 Hz and 345 mA @10 kHz) let designers match the capacitor to supply and decoupling demands.
• Controlled dissipation — Provided tanδ value (0.24 at 20 °C, 120 Hz, 10 V) enables assessment of dielectric losses during design validation.
• Endurance at elevated temperature — 2000 hours at 85 °C rating supports predictable aging and lifecycle planning for deployed audio equipment.
• Practical packaging options — Available in bulk (no terminal forming) or bag packing to suit prototyping and production processes.
