UKW2A220MED

The UKW2A220MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, optimized for audio and AV equipment. It combines a 22 µF capacitance with a 100 V rated voltage in a compact φ6.3 × 11 mm can for use in signal and power conditioning within audio circuits.

Designed around a purpose-driven electrolyte formulation, the UKW series targets balanced sound quality while delivering durable performance across a −40°C to 85°C operating range and a 2000-hour endurance at 85°C.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for higher-voltage audio stages and decoupling tasks.
• Audio-Optimized Electrolyte: UKW series chemistry engineered for a harmonious balance of sound quality, making it well suited for AV and audio equipment.
• Low Loss (tan δ): Tangent of loss angle (tan δ) 0.08 measured at 120 Hz, 20°C and 100 V, indicating low dissipation for audio-frequency applications.
• Ripple Handling: Rated ripple currents of 120 mA at 120 Hz (low frequency) and 240 mA at 10 kHz (high frequency), supporting both power-filtering and higher-frequency ripple conditions.
• Leakage Current: Specified leakage current of 66 µA, supporting stable performance in DC-coupled audio circuits.
• Reliability & Endurance: 2000 hours rated life at 85°C with specified recovery characteristics after endurance testing, providing predictable long-term behavior.
• Mechanical & Mounting: Radial lead can package with a diameter of 6.3 mm and length of 11 mm (φ6.3×11L), lead spacing 2.5 mm ±0.5 mm, available in bulk or bag packing (no terminal forming).
• Environmental Compliance: RoHS compliant.

Typical Applications

• Audio Amplifiers: Decoupling and power-supply filtering in amplifier stages where 100 V rating and low loss (tan δ) support clean audio performance.
• AV Receivers and Signal Paths: Coupling and smoothing in AV equipment where series-designed electrolyte helps deliver balanced sound quality.
• Consumer Audio Electronics: Local supply filtering and coupling in preamplifiers, tone stages, and other audio circuit blocks requiring compact high-voltage capacitors.

Unique Advantages

• Audio-Focused Electrolyte: Formulation targeted at delivering a harmonious balance of sound quality, beneficial for designers prioritizing audio fidelity.
• High Voltage Capability in a Small Footprint: 100 V rating in a compact φ6.3×11 mm can enables use in space-constrained, higher-voltage audio stages.
• Measured Low Dissipation: tan δ = 0.08 at 120 Hz (20°C, 100 V) reduces loss at audio frequencies, supporting clearer signal paths.
• Broad Ripple Frequency Support: Specified ripple current values at both low and high frequencies cover common audio and switching-related ripple conditions.
• Predictable Endurance: 2000-hour rating at 85°C helps designers plan long-term performance and reliability in end equipment.
• RoHS Compliance: Meets RoHS directive requirements for environmentally conscious designs.
