UKW1J221MPD

The UKW1J221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, designed for audio and AV equipment. It provides 220 µF capacitance at a 63 V rating with an audio-optimized electrolyte formulation intended to support a harmonious balance of sound quality.

Engineered for circuit decoupling, power smoothing and filtering in audio signal paths, this compact φ10 × 16 mm can delivers specified ripple performance across low- and high-frequency ranges while meeting a -40°C to 85°C operating window and 2000-hour endurance at 85°C.

Key Features

• Core electrical performance — 220 µF capacitance with ±20% tolerance at 120 Hz, rated for 63 V DC. Polarized design suitable for conventional electrolytic applications.
• Loss and leakage — tanδ (DF) 0.10 measured at 20°C, 120 Hz and leakage current specified at 415.8 µA, enabling predictable impedance and low-loss behavior in audio circuits.
• Ripple handling — Low-frequency ripple current of 470 mA (120 Hz) and high-frequency ripple current of 705 mA (10 kHz), supporting both power-supply smoothing and higher-frequency decoupling tasks.
• Reliability and lifetime — Endurance rated at 2000 hours at 85°C with specified limits for capacitance change, tanδ and leakage current after the test period.
• Mechanical and packaging — Compact radial can, φ10 × 16 mm (diameter × length) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) / bag packing for flexible assembly options.
• Environmental compliance — RoHS compliant as part of the UKW series' adherence to applicable RoHS directives.

Typical Applications

• Audio amplifiers and preamps — Local power smoothing and decoupling where stable capacitance and audio-focused electrolyte characteristics help maintain signal integrity.
• AV receivers and consumer audio equipment — General-purpose bulk capacitance for power rails and filter networks in AV systems designed around the UKW series.
• Power supply filtering — DC-link and post-regulator smoothing in designs up to 63 V requiring a compact radial solution with defined ripple capability.

Unique Advantages

• Audio-optimized electrolyte: Series-level development targeted at a harmonious balance of sound quality, supporting audio and AV applications.
• Verified ripple performance: Specified ripple currents at 120 Hz and 10 kHz provide clear guidance for both low- and high-frequency filtering design margins.
• Compact radial can: φ10 × 16 mm package with 5 mm lead spacing makes it straightforward to integrate into dense PCBs and compact audio assemblies.
• Long endurance at elevated temperature: 2000 hours at 85°C ensures component behavior is characterized for extended operation in warm environments.
• Predictable electrical characteristics: Low tanδ (0.10 at 20°C, 120 Hz) and a specified leakage current (415.8 µA) help designers model circuit performance accurately.
• RoHS compliant: Environmentally compliant manufacturing aligns with modern regulatory requirements for electronics assemblies.
