UKW1C222MHD

The UKW1C222MHD is a radial-lead aluminum electrolytic capacitor designed for audio and AV equipment. It delivers 2200 µF capacitance at a 16 V rating with a polarized can package optimized for high sound quality and low-frequency stability.

Built on Nichicon's UKW series design, this component targets audio applications requiring high capacitance, reliable ripple handling, and RoHS-compliant materials for long-term operation across a broad temperature range.

Key Features

• High Capacitance (2.2 mF) — 2200 µF provides substantial energy storage for power-supply smoothing and decoupling in audio circuits.
• 16 V Rated Voltage — Suitable for low-voltage audio power rails and AV preamp/amp stages.
• Radial Lead, Can Package — Through-hole radial-lead construction simplifies assembly and replacement in chassis-mounted audio equipment.
• Audio-Optimized Electrolyte — UKW series development emphasizes a harmonious balance of sound quality specifically for AV and audio equipment.
• Operating Temperature Range — −40°C to +85°C for reliable performance across typical consumer and professional audio environments.
• Endurance — Rated for 2000 hours at 85°C under rated voltage to support long-term operation in heated enclosures.
• Ripple Current Capability — Specified ripple handling of 1.25 A at 120 Hz and 1.438 A at 100 kHz to manage supply ripple in audio power stages.
• Leakage Current Specification — Series leakage limits provided as 0.03 CV (µA) after 1 minute and 0.01 CV after 2 minutes (at 20°C), enabling predictable bias behavior.
• Capacitance Tolerance — ±20% tolerance (at 120 Hz, 20°C) for predictable filter and coupling performance.
• RoHS Compliant — Conforms to RoHS directive requirements for material compliance.

Typical Applications

• AV Receivers and Amplifiers — Bulk supply filtering and reservoir capacitance where high audio-quality smoothing is required.
• Professional Audio Gear — Power supply decoupling and energy storage in mixers, preamps, and studio equipment.
• Consumer Audio Electronics — Filtering and coupling in home theater systems, powered speakers, and audio sources.

Unique Advantages

• Audio-focused Electrolyte: Engineered formulation in the UKW series promotes a balanced sound character suited to AV equipment.
• Substantial Energy Density: 2200 µF capacitance provides strong smoothing capability, reducing ripple and supporting stable power delivery to audio circuits.
• Verified Ripple Performance: Rated ripple currents at both 120 Hz and high frequency give designers clear margins for supply-decoupling and switching-noise mitigation.
• Wide Operating Range: −40°C to +85°C operation and 2000-hour endurance at 85°C support reliable use in varied consumer and pro-audio environments.
• Predictable Leakage Behavior: Leakage current specifications tied to CV values aid in bias planning and DC operating point stability.
• RoHS Compliance: Use in products requiring restricted-substance conformity without additional material qualification.
