UKW1H220MDD

The UKW1H220MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, optimized for audio and AV equipment. It provides 22 µF capacitance at a 50 V rating in a compact φ5×11 mm can and is designed to support audio signal and power-decoupling applications where low loss and controlled leakage matter.

Key value comes from audio-oriented electrolyte chemistry and a balance of electrical performance — low tanδ, modest leakage, and defined ripple handling — combined with RoHS-compliant construction. Note: Status – End Of Life.

Key Features

• Electrical Rating — 22 µF nominal capacitance with tolerance -20% to +20% and a 50 V rated voltage.
• Low Loss — tanδ = 0.12 (max) measured at 20°C, 120 Hz, supporting lower dissipation in audio circuits.
• Leakage Current — Specified leakage current of 33 µA for improved signal integrity in coupling and timing applications.
• Ripple Handling — Low-frequency ripple current 95 mA at 120 Hz and high-frequency ripple current 190 mA at 10 kHz to address both power-supply and higher-frequency ripple components.
• Reliability & Endurance — Rated for 2000 hours at 85°C, meeting endurance expectations for many AV equipment designs.
• Operating Range — Temperature range from -40°C to +85°C for operation across common consumer and professional audio environments.
• Form Factor & Mounting — Radial leaded can, size φ5×11 mm (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Packaging — Supplied in bulk (no terminal forming) or bag packing for volume assembly or prototyping.
• Regulatory — RoHS compliant.

Typical Applications

• Audio and AV Equipment — Used for signal coupling, DC blocking, and local decoupling in consumer and professional audio systems where tonal balance and low dissipation are important.
• Power Supply Filtering — Provides local smoothing and ripple suppression on 50 V rails in compact through-hole power sections.
• Signal Conditioning — Employed in analog front-ends and filter networks where controlled leakage and low tanδ support fidelity.

Unique Advantages

• Audio-Optimized Electrolyte — UKW series design targets a harmonious balance of sound quality, making the part suitable for AV and audio-focused circuits.
• Compact Through-Hole Package — φ5×11 mm can and tight 2 mm lead spacing enable compact PCB layouts in space-constrained designs.
• Defined Loss Characteristics — Low tanδ at standard measurement conditions (0.12 at 20°C, 120 Hz) helps minimize dissipation in audio paths.
• Ripple Handling Across Frequencies — Specified ripple current values for both low (95 mA @120 Hz) and high (190 mA @10 kHz) frequency content support mixed-spectrum filtering tasks.
• Durability at Elevated Temperature — 2000-hour endurance at 85°C provides predictable long-term behavior in warmed enclosures.
• Low Leakage — 33 µA leakage helps preserve DC bias and low-frequency response in coupling applications.
