UKL1E222MHD

The UKL1E222MHD is an aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series, provided in a radial-lead can package. It delivers 2200 µF capacitance at a 25 V rating with a ±20% tolerance, optimized for applications where low leakage and reliable ripple handling are required.

Designed for electronics such as audio equipment, this radial, polarized capacitor combines substantial capacitance, defined ripple-current capability at both low and high frequencies, and a rated endurance of 2000 hours at 85°C, while meeting RoHS requirements.

Key Features

• Capacitance & Tolerance — 2200 µF nominal capacitance with ±20% tolerance (M).
• Rated Voltage & Polarization — 25 V rated voltage; polarized aluminum electrolytic design suitable for DC filtering and decoupling use.
• Low Leakage Current — Specified leakage current of 110 µA, supporting reduced DC loss in bias-sensitive circuits.
• Ripple Current Capability — Low-frequency ripple current: 1.44 A (120 Hz); high-frequency ripple current: 1.656 A (10 kHz), enabling reliable performance across common power and audio frequencies.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with operating range from −40°C to +85°C.
• Mechanical & Mounting — Radial lead, can-style package sized φ16 × 35.5 mm with 7.5 mm lead spacing (±0.5 mm tolerance) for straightforward through-hole assembly.
• Packaging Options & Compliance — Available in Bulk (no terminal forming) or Bag packing; RoHS compliant.

Typical Applications

• Audio equipment — Power supply smoothing and decoupling in audio circuits where low leakage and stable ripple handling improve signal integrity.
• Power supply filtering — Bulk energy storage and waveform smoothing in DC power rails that require high capacitance at 25 V.
• General electronics — Through-hole radial mounting for repair, prototyping, or designs preferring can-style electrolytic capacitors with defined endurance at elevated temperature.

Unique Advantages

• Low DC leakage: 110 µA leakage current reduces standby losses and preserves bias conditions in sensitive circuits.
• Defined ripple performance: Specified ripple current at both 120 Hz and 10 kHz supports stable thermal and electrical behavior across common operating frequencies.
• High capacitance in a compact can: 2200 µF in a φ16 × 35.5 mm package provides substantial energy storage without large PCB footprint increases.
• Durability at elevated temperature: 2000 hours rated life at 85°C gives predictable longevity for sustained thermal conditions.
• Through-hole simplicity: Radial-lead construction and standard 7.5 mm lead spacing ease assembly and replacement in legacy and serviceable designs.
• RoHS compliant: Meets environmental directives for lead-free manufacturing requirements.
