UKL1A222KHD

The UKL1A222KHD is a radial-lead, low-leakage aluminum electrolytic capacitor offering 2200 µF capacitance at a 10 V rating. Designed for audio applications, it combines high capacitance density with controlled leakage and robust ripple-current handling in a compact φ16×25 mm can.

Key attributes include low leakage current, rated ripple current at both low and high frequencies, a 2000-hour endurance at 85°C, and a wide operating temperature range, making it suitable for power-smoothing and decoupling roles in consumer audio electronics and related equipment.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with ±10% tolerance at a 10 V rating, providing significant bulk energy storage in a compact package.
• Low Leakage — Low leakage current specified at 44 µA, reducing stand-by losses and preserving bias conditions in audio circuits.
• High Ripple Current Capability — Supports 1.2 A low-frequency ripple (120 Hz) and 1.38 A high-frequency ripple (10 kHz), enabling effective smoothing under dynamic load conditions.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with an operating range of −40°C to +85°C, suitable for sustained operation in typical consumer environments.
• Radial Lead Package — φ16×25 mm aluminum can with 7.5 mm lead spacing (±0.5 mm) for easy through-hole mounting and reliable mechanical retention.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Audio power supply smoothing — Bulk energy storage and ripple reduction for analog and digital audio amplifier supplies.
• Decoupling in audio electronics — Local decoupling and stabilization for preamplifiers, DACs, and DSP power rails where low leakage is beneficial.
• Filter circuits — Use in low-frequency filtering and coupling networks within consumer audio equipment.

Unique Advantages

• Reduced stand-by loss: Low leakage current (44 µA) helps maintain bias and reduces power loss when circuits are idle.
• Broad ripple performance: Specified ripple currents at both 120 Hz and 10 kHz provide predictable thermal and electrical behavior across audio-relevant frequencies.
• Compact high-capacity option: 2200 µF in a φ16×25 mm can saves board space while delivering substantial capacitance for bulk smoothing.
• Through-hole reliability: Radial-lead construction with defined 7.5 mm lead spacing allows robust solder connections and easy replacement or rework.
• Long endurance at elevated temperature: 2000 hours at 85°C supports long-term operation in consumer and professional audio equipment.
• Regulatory compliance: RoHS-compliant materials simplify integration into regulated product lines.
