UKL1H220KED

The UKL1H220KED is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, optimized for low leakage current and compact through-hole mounting. It provides 22 µF capacitance at a 50 V rating in a φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for audio and compact electronic equipment, this capacitor delivers low leakage (2.2 µA) and controlled loss (tanδ = 0.08 at 20°C, 120 Hz) with rated endurance of 2000 hours at 85°C.

Key Features

• Capacitance & Voltage 22 µF nominal capacitance with ±10% tolerance at a 50 V rated voltage for moderate energy-storage and decoupling needs.
• Low Leakage Current Specified leakage current of 2.2 µA supports applications where minimal bleed current is important.
• Loss Angle (tan δ) tanδ = 0.08 measured at 20°C, 120 Hz, indicating controlled dissipation for stable performance in signal and power paths.
• Ripple Current Capability Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 220 mA (10 kHz) for handling AC components on supply rails.
• Endurance & Temperature Range Rated for 2000 hours at 85°C and operable from −40°C to +85°C to match a range of environmental conditions.
• Compact Radial Can φ6.3 × 11 mm package with 2.5 mm lead spacing and radial-lead mounting for straightforward through-hole assembly in space-constrained designs.
• RoHS Compliant Conforms to RoHS requirements as noted for the UKL series.
• Packaging Options Available in bulk (no terminal forming) and bag packing for flexible procurement and inventory handling.

Typical Applications

• Audio Equipment Low leakage and controlled loss make this capacitor suitable for audio circuitry where bias stability and low distortion are important.
• Power Supply Decoupling in Compact Electronics Compact φ6.3 × 11 mm radial can fits tight PCB real estate while providing bulk decoupling and ripple filtering.
• Repair and Maintenance of Legacy Boards Through-hole radial mounting and standard dimensions support service and replacement in established designs.

Unique Advantages

• Low Standby Drain: 2.2 µA leakage helps minimize unwanted current draw in bias and standby circuits.
• Controlled Dissipation: tanδ = 0.08 at 120 Hz supports predictable thermal and electrical behavior in audio and power paths.
• Compact Footprint: φ6.3 × 11 mm can and 2.5 mm lead spacing reduce board space impact while enabling robust through-hole mounting.
• Frequency-Responsive Ripple Handling: Rated ripple currents provided for both low- and high-frequency conditions (110 mA at 120 Hz, 220 mA at 10 kHz) for mixed-signal and power-decoupling tasks.
• Robust Operating Window: −40°C to +85°C operating range and 2000 h endurance at 85°C for reliable performance across common operating environments.
• Regulatory Compliance: RoHS-compliant construction supports use in regulated product builds.
