UKL1V220MED

The UKL1V220MED is a low-leakage aluminum electrolytic capacitor in a compact radial-lead can. It delivers 22 µF capacitance at a 35 V rating with low leakage current and specified ripple current performance for audio and general-purpose power-decoupling applications.

This part has a 2000 h endurance rating at 85°C and an operating temperature range of −40°C to 85°C. Note: this product is designated End Of Life; availability should be confirmed before specifying into new production designs.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with ±20% tolerance and a rated voltage of 35 V, suitable for mid-voltage decoupling and smoothing tasks.
• Low Leakage Current: Specified leakage current of 1.54 µA, minimizing DC loss and preserving bias conditions in sensitive circuits.
• Ripple Current Performance: Rated for 110 mA at 120 Hz (low frequency) and 220 mA at 10 kHz (high frequency) to handle both power-line and higher-frequency switching ripple.
• Endurance and Temperature: 2000 hours life at 85°C and an operating range of −40°C to 85°C for sustained performance in typical electronics environments.
• Compact Radial Package: φ6.3 × 11 mm can with 2.5 mm lead spacing and radial-lead mounting for through-hole PCB designs; supplied in bulk or bag packing.
• RoHS Compliant: Meets RoHS directive requirements for restricted substances.

Typical Applications

• Audio Equipment: Power-supply smoothing and decoupling in audio circuits where low leakage and defined ripple handling help preserve signal integrity.
• Power Supply Filtering: Local decoupling for mid-voltage rails in consumer and industrial electronics, leveraging its ripple current capability.
• General-Purpose Electronics: Through-hole radial mounting for legacy boards and repair applications requiring a compact electrolytic solution.

Unique Advantages

• Low leakage for stable DC conditions: 1.54 µA leakage supports circuits that require minimal standby current and stable bias voltages.
• Dual-frequency ripple capability: Rated ripple currents at 120 Hz and 10 kHz address both mains-derived and switching-frequency ripple without overstressing the part.
• Small footprint, rugged radial can: φ6.3 × 11 mm body with 2.5 mm lead spacing allows compact placement on through-hole PCBs and straightforward soldering.
• Long endurance at elevated temperature: 2000 hours at 85°C provides predictable lifetime behavior for designs operating within the specified temperature range.
• Regulatory compliance: RoHS conformity simplifies integration where restricted-substance compliance is required.

Why Choose UKL1V220MED?

UKL1V220MED combines low leakage, defined ripple current capability, and a compact radial package to address power-smoothing and decoupling needs in audio and general-purpose electronic designs. Its 2000 h endurance at 85°C and −40°C to 85°C operating range provide predictable, documented performance for applications operating within those thermal limits.

Because this part is designated End Of Life, it is most appropriate for repair, maintenance, or designs that accept limited lifetime availability. Confirm availability and stock status before committing the UKL1V220MED to production builds.

Request a quote or contact sales to confirm current availability, lead times, and to discuss alternative options if long-term sourcing is required for your design.
