UFW1A222MPD

The UFW1A222MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UFW series designed for audio equipment. It delivers high bulk capacitance (2200 µF) at a 10 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing, offering measurable ripple handling and predictable endurance for audio-focused power and decoupling applications.

Key electrical characteristics include specified low- and high-frequency ripple current ratings, controlled leakage, and an endurance rating of 2000 hours at 85°C, making the part suitable for designs that require sustained performance in the specified temperature range.

Key Features

• High Capacitance (2.2 mF) — 2200 µF bulk capacitance for energy storage and smoothing in low-voltage audio circuits.
• 10 V Rated Voltage — Designed for low-voltage audio rails and related circuits that require polarized electrolytic capacitance.
• Defined Ripple Performance — 1050 mA ripple current at 120 Hz and 1207.5 mA at 10 kHz, specified to support both low- and high-frequency ripple conditions.
• Low Leakage Current — 660 µA leakage current specification to help maintain DC bias integrity over time.
• Endurance at Elevated Temperature — Rated for 2000 hours at 85°C, with post-test limits of ±20% capacitance change and leakage not exceeding initial spec.
• Compact Radial Can Package — φ10 × 20 mm body, radial leads with 5 mm lead spacing; supplied bulk/bag packing (no terminal forming).
• Operating Temperature Range — −40°C to +85°C to cover typical environmental conditions for audio equipment.
• Tolerance and Loss — ±20% capacitance tolerance and specified tan δ of 0.22 for this part to aid in predictable frequency response planning.

Typical Applications

• Audio Equipment — Bulk energy storage and power-rail smoothing in audio amplifiers, preamps, and related modules where 2200 µF at 10 V is required.
• Power-rail Decoupling — Local decoupling on low-voltage audio boards benefiting from the capacitor’s ripple current ratings and capacitance.
• Signal-chain Support — Use in audio system power subsystems where controlled leakage and defined loss tangent contribute to stable performance over time.

Unique Advantages

• Substantial Bulk Capacitance: 2200 µF provides significant energy reserve for low-voltage audio rails, reducing ripple and supporting transient currents.
• Dual-frequency Ripple Capability: Explicit ripple ratings at 120 Hz (1.05 A) and 10 kHz (1.208 A) make it straightforward to evaluate performance across audio-relevant frequencies.
• Compact, Board-friendly Form: φ10 × 20 mm radial can with 5 mm lead spacing fits tight layouts while offering through-hole robustness for assembly.
• Endurance Specification: 2000 hours at 85°C gives designers a defined lifecycle metric for thermal stress and long-term stability planning.
• Predictable Leakage and Loss: 660 µA leakage and 0.22 tan δ help designers model DC bias and frequency response reliably.
• Audio-focused Series: Part of Nichicon’s UFW series specified for audio equipment, aligning component selection with application intent.
