UKL1A222MHD

The UKL1A222MHD is a low-leakage aluminum electrolytic capacitor in a radial-lead can, offering 2200 µF capacitance at 10 V with polarized construction. It targets audio applications and other through-hole designs that require substantial capacitance with controlled leakage and defined ripple handling.

Key electrical characteristics include low-frequency ripple current of 1.2 A (120 Hz), high-frequency ripple capability of 1.38 A (10 kHz), and a measured leakage current of 44 µA. Note: this part is designated End Of Life.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal with a rated voltage of 10 V and capacitance tolerance ±20% for design certainty.
• Low Leakage Performance — Specified leakage current of 44 µA to support circuits where minimal DC loss is important.
• Ripple Current Handling — Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 1.38 A (10 kHz) for reliable filtering under varying ripple conditions.
• Endurance & Temperature Range — Rated lifetime of 2000 hours at 85°C with an operating temperature range of −40°C to +85°C for consistent performance in warm environments.
• Package & Mounting — Radial lead, polarized can package (φ16 × 25L) with 7.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing to support manual assembly and repairs.
• Regulatory — RoHS compliant.

Typical Applications

• Audio electronics — Energy storage and smoothing in audio power supplies where low leakage helps maintain bias and reduce hum.
• Audio amplification modules — Bulk decoupling and reservoir capacitance to support transient current demands in amplifier circuits.
• Service, repair & legacy systems — Replacement or spare component for through-hole audio equipment and other legacy designs that specify a 2200 µF, 10 V radial electrolytic with low leakage.

Unique Advantages

• Measured low leakage — 44 µA leakage current supports circuits sensitive to DC bleed and bias stability.
• Dual-frequency ripple capability — Rated ripple currents at both 120 Hz (1.2 A) and 10 kHz (1.38 A) indicate suitability across a range of ripple spectra common in power-supply and audio environments.
• Compact through-hole form factor — φ16 × 25L radial can with 7.5 mm lead spacing provides a compact, serviceable option for through-hole assemblies and repairs.
• Designed endurance — 2000 hours at 85°C specified life gives a defined reliability expectation for designs operating in elevated-temperature conditions.
• RoHS compliance — Meets RoHS directive requirements for environmental compliance in applicable assemblies.
