UCY2E220MPD

The UCY2E220MPD is a radial-lead aluminum electrolytic capacitor offering 22 µF capacitance at a 250 V rating in a compact φ10 × 16 mm can. It is part of Nichicon’s UCY series of miniature, high-ripple-current, long-life capacitors.

Designed for demanding power circuitry, the UCY2E220MPD targets applications that require high ripple handling, extended endurance at elevated temperatures, and through-hole mounting. Its key value propositions are high ripple-current capability, a 10,000-hour endurance at 105°C, and AEC-Q200 qualification for demanding environments.

Key Features

• Electrical Performance — 22 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 250 V for mid-voltage power applications.
• Loss and Leakage — Tangent of loss angle (tan δ) of 0.20 measured at 20°C, 120 Hz, and a specified leakage current of 320 µA for predictable dissipation and low DC loss.
• High Ripple Current — Low-frequency ripple current of 225 mA at 120 Hz and high-frequency ripple current of 450 mA at 100 kHz, supporting power supply filtering and decoupling duties.
• Long Life and Reliability — Rated for 10,000 hours at 105°C under specified conditions, with endurance limits defined for capacitance, tan δ, and leakage current.
• Package and Mounting — Radial lead, can-type package (φ10 × 16 mm) with 5.0 mm lead spacing for straightforward through-hole assembly; available in bulk (no terminal forming) or bag packing.
• Operating Environment — Wide operating temperature range from −40°C to +105°C and RoHS compliance for environmental compatibility.

Typical Applications

• Automotive power modules — AEC-Q200 qualification and extended life at 105°C make this capacitor suitable for automotive electronic power circuits and modules.
• Power supply filtering — Compact radial package and robust ripple-current ratings provide effective smoothing and decoupling in industrial and commercial power supplies.
• Ballast and lighting power circuits — Engineered for ballast applications with high ripple capability and long operational life.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 225 mA (120 Hz) and 450 mA (100 kHz) enable reliable suppression of AC ripple in power stages.
• Extended elevated-temperature life: 10,000-hour endurance at 105°C supports long-term reliability in thermally stressful installations.
• Automotive-grade qualification: AEC-Q200 rating signals suitability for applications demanding higher reliability and qualification traceability.
• Compact through-hole form factor: φ10 × 16 mm can and 5 mm lead spacing provide a small footprint for space-constrained PCB layouts while retaining robust leaded mounting.
• Frequency performance scaling: Series frequency coefficients allow increased ripple-current capability at higher frequencies (coefficient up to 2.0 at 100 kHz), supporting modern switching supplies.
• Regulatory compliance: RoHS compliance supports use in regulated designs and markets.
