UKL1C222MHD

The UKL1C222MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL low-leakage series. It provides 2200 µF capacitance at a 16 V rating in a compact φ16 × 25 mm can, delivering low leakage and robust ripple-handling for audio-oriented power circuits.

Engineered for applications that require bulk energy storage and smoothing, this polarized radial component combines a high nominal capacitance with rated ripple current and a −40 °C to 85 °C operating range for reliable performance in consumer and professional audio equipment.

Key Features

• Capacitance & Voltage — 2200 µF (2.2 mF) nominal capacitance with ±20% tolerance at 16 V rated voltage provides substantial bulk storage for power-supply smoothing.
• Low Leakage Current — Specified leakage current of 70.4 µA supports low-standby-loss designs and helps preserve bias conditions in sensitive audio circuits.
• High Ripple Capability — Rated low-frequency ripple current of 1.3 A (120 Hz) and high-frequency ripple current of 1.495 A (10 kHz) to handle dynamic load conditions common in audio power stages.
• Mechanical & Mounting — Radial lead, polarized aluminum can in a φ16 × 25 mm package with 7.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB mounting and manual assembly or bulk/bag packing.
• Temperature and Endurance — Operates from −40 °C to 85 °C with an endurance rating of 2000 hours at 85 °C, supporting sustained operation under elevated ambient temperatures.
• Regulatory — RoHS-compliant construction in the UKL low-leakage series.

Typical Applications

• Audio Power Supplies — Bulk smoothing and decoupling in amplifier and audio system power rails, benefitting from the 2200 µF capacitance and high ripple current ratings.
• Preamp and Signal Chain Biasing — Low leakage current helps maintain DC bias and reduces drift in sensitive preamplifier and input-stage circuits.
• Audio Subsystems — Energy storage and transient buffering in mixers, powered crossovers, and consumer/professional audio modules where compact radial packages are required.

Unique Advantages

• Substantial Bulk Capacitance: 2200 µF provides large energy reserve for smoothing and transient support in audio power systems.
• Low Standby Loss: Measured leakage of 70.4 µA minimizes drain on supply rails, preserving bias and reducing idle power consumption.
• Ripple-Ready: Dual ripple-current specs (1.3 A at 120 Hz, 1.495 A at 10 kHz) accommodate both mains-frequency filtering and higher-frequency switching environments.
• Compact Radial Form Factor: φ16 × 25 mm can with 7.5 mm lead spacing fits common through-hole layouts while offering straightforward mechanical mounting.
• Rated Endurance: 2000 hours at 85 °C supports predictable life performance in warm operating conditions.
• RoHS Compliance: Environmentally compliant construction for regulated product assemblies.
