UKL1E222KHD

The UKL1E222KHD is a radial-lead aluminum electrolytic capacitor offering 2200 µF capacitance at 25 V with a ±10% tolerance. Part of Nichicon's UKL series, it is designed for applications where low leakage and robust ripple handling are required—specifically noted for audio use.

Key electrical characteristics include low leakage current (110 µA), rated ripple currents of 1.44 A at 120 Hz and 1.656 A at 10 kHz, and an endurance rating of 2000 hours at 85°C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance at a 25 V rating with a ±10% (K) tolerance for predictable bulk energy storage.
• Low Leakage — Series low-leakage design with a specified leakage current of 110 µA, minimizing bias drift in long-duration circuits.
• High Ripple Handling — Low-frequency ripple current of 1.44 A (120 Hz) and high-frequency ripple current of 1.656 A (10 kHz) to support demanding audio supply conditions.
• Reliability & Lifetime — Endurance specified at 2000 hours at 85°C, with performance limits defined for capacitance change, tan δ, and leakage after life test.
• Radial Through-Hole Package — φ16 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial leads for straightforward through-hole mounting.
• Environmental Compliance — RoHS compliant per product data.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit repair and production workflows.

Typical Applications

• Audio Amplifiers — Bulk capacitance and high ripple capability help stabilize supply rails and support transient current demands.
• Consumer Audio Equipment — Low leakage and large capacitance make it suitable for power supply filtering in stereos, receivers, and powered speakers.
• Power Supply Filtering — Through-hole radial format and robust ripple ratings support smoothing and decoupling in low- to mid-power audio-focused power supplies.

Unique Advantages

• Reduced Bias Drift: Low leakage current (110 µA) preserves DC bias stability over prolonged operation.
• Handles Audio Transients: Specified ripple current at both 120 Hz and 10 kHz supports real-world audio power demands across frequency bands.
• Through-Hole Robustness: Radial can construction and 7.5 mm lead spacing provide mechanical strength for repairable and serviceable designs.
• Compact Energy Density: 2200 µF in a φ16 × 35.5 mm can delivers significant capacitance in a small through-hole footprint.
• Regulated Lifetime Expectancy: 2000 hours at 85°C gives a defined endurance metric for thermal and lifetime planning.
• RoHS Compliance: Meets RoHS directive requirements for environmental compliance in applicable regions.

Why Choose UKL1E222KHD?

The UKL1E222KHD delivers a combination of high capacitance, low leakage, and defined ripple performance in a compact radial package, making it a practical choice for audio-focused power filtering and supply stabilization where through-hole mounting is preferred. Its endurance rating at elevated temperature provides a predictable reliability baseline for thermal-design decisions.

Because this part is marked End Of Life, it is appropriate for repair, legacy support, or replenishment scenarios where the exact replacement is required. Evaluate inventory and lifecycle impact accordingly when planning production or maintenance use.
