UFW1J220MDD

The UFW1J220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UFW series, designed for audio applications. It provides 22 µF capacitance at a 63 V rating in a compact φ5×11L package, delivering low dissipation and stable performance across a wide temperature range.

Engineered for use in audio circuitry and related power/decoupling tasks, this polarized through-hole capacitor combines a low tangent of loss angle and specified ripple current ratings to support reliable signal and power conditioning in consumer and professional audio designs.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of -20% to +20%.
• Low Dissipation Factor — tanδ = 0.1 (measured at 20°C, 120 Hz) for reduced loss in audio-frequency applications.
• Ripple Current Performance — Low-frequency ripple current of 100 mA at 120 Hz and high-frequency ripple current of 200 mA at 10 kHz, enabling handling of audio and switching-related ripple components.
• Leakage Current — Specified leakage current of 41.58 µA, suitable for stable bias conditions in signal and power circuits.
• Mechanical & Mounting — Radial lead, polarized can with lead spacing of 2 mm (±0.5 mm), package type: Radial, Can; available in Bulk (no terminal forming) or Bag packing.
• Temperature & Endurance — Operating range −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Compact Dimensions — Size specified as φ5×11L (SizeDimension: L: 1.1 × D: 0.5 cm), suitable for space-constrained through-hole board layouts.

Typical Applications

• Audio Equipment — Use for power-supply filtering, decoupling and coupling in audio amplifiers and consumer audio devices where low loss and stable capacitance are required.
• Preamp and Signal Circuits — Suitable for audio-frequency signal conditioning and DC blocking where a polarized electrolytic is required.
• Power Supply Decoupling — Provides local energy storage and ripple smoothing in audio and small-signal power supplies operating up to 63 V.

Unique Advantages

• Audio-focused dielectric characteristics — The UFW series is specified for audio equipment and this part’s low tanδ at 120 Hz supports lower loss in audio paths.
• Balanced ripple capability — Distinct low- and high-frequency ripple current ratings (100 mA @120 Hz, 200 mA @10 kHz) help address both mains-frequency and switching/noise components.
• Robust temperature endurance — Rated for operation from −40°C to +85°C with 2000 hours endurance at 85°C for predictable long-term behavior in typical electronic environments.
• Compact through-hole form — φ5×11L radial can with 2 mm lead spacing supports easy insertion and soldering in dense PCB layouts and legacy through-hole designs.
• Clear leakage specification — Defined leakage current (41.58 µA) enables predictable bias and low-current circuit designs.
• Multiple packing options — Bulk (no terminal forming) and bag packing allow flexible handling and assembly preparation for production or prototyping.
