UKL1E221MPD

The UKL1E221MPD is a Nichicon UKL series aluminum electrolytic capacitor in a radial-lead can package. It delivers 220 µF capacitance at a 25 V rating with low leakage characteristics and a compact φ10×16 mm footprint suitable for space-constrained boards.

Designed for audio applications and general-purpose power filtering, this polarized radial capacitor offers measurable low-frequency and high-frequency ripple handling plus a 2000-hour endurance at 85 °C, making it suited to designs that require stable capacitance and low losses over extended operation.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing bulk decoupling and energy storage in low-voltage circuits.
• Low Leakage — Specified leakage current of 11 µA at 20 °C, supporting low-standby-loss applications and minimizing DC offset issues.
• Loss Angle (tanδ) — tanδ = 0.12 measured at 20 °C, 120 Hz, indicating controlled dissipation for audio and power applications.
• Ripple Current Performance — Rated ripple currents of 400 mA at 120 Hz (low frequency) and 600 mA at 10 kHz (high frequency), enabling both power-supply smoothing and higher-frequency decoupling.
• Endurance and Temperature Range — 2000 hours life at 85 °C and operating range from −40 °C to 85 °C for reliable performance in varied thermal environments.
• Package and Mounting — Radial lead can, φ10×16 mm size with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for manual or automated assembly preparation.
• RoHS Compliant — Meets RoHS requirements for environmental regulatory adherence.

Typical Applications

• Audio equipment — Suitable for decoupling and smoothing in audio power supplies and signal-chain support where 220 µF/25 V polarized capacitance is required.
• Power filtering — Provides bulk energy storage and ripple attenuation in low-voltage power rails.
• Consumer electronics — Compact radial package fits space-constrained boards that need reliable electrolytic capacitance and low leakage.

Unique Advantages

• Measured low leakage — 11 µA leakage current reduces idle power loss and helps maintain DC bias stability in sensitive circuits.
• Balanced ripple capability — Both low- and high-frequency ripple current ratings (400 mA @120 Hz and 600 mA @10 kHz) support a range of filtering tasks without overstressing the part.
• Stable dissipation — tanδ value of 0.12 at standard test conditions indicates controlled dielectric losses for audio and power applications.
• Durable operating life — 2000 hours at 85 °C provides predictable end-of-life behavior for product lifetime planning.
• Compact radial form factor — φ10×16 mm can body and 5.0 mm lead spacing simplify placement in tight layouts while retaining sufficient capacitance.
• Regulatory compliance — RoHS status supports designs targeting restricted-substance requirements.
