UHW1K221MPD

The UHW1K221MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It combines 220 µF capacitance with an 80 V rated working voltage, optimized for low impedance at high frequency and elevated ripple-current capability.

Engineered for applications requiring compact size and sustained performance across −40 °C to 105 °C, this component delivers long endurance (12,000 h at 105 °C) and RoHS compliance for modern electronic assemblies.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with an 80 V rated voltage and a tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 810 mA (120 Hz) and high-frequency ripple current of 1.62 A (10 kHz), supporting higher AC load conditions.
• Low Impedance — Rated impedance of 280 mΩ and lower impedance at high frequency as specified in the series datasheet, aiding in effective filtering and decoupling.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.09 measured at 20 °C, 120 Hz, for predictable dissipation behavior.
• Leakage Current — Specified leakage current of 176 µA for controlled off-state current in steady conditions.
• Long Endurance — Endurance rating of 12,000 hours at 105 °C, supporting extended operation under elevated temperature and ripple stress.
• Compact Radial Package — φ10 × 25 mm can with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies and manual or automated insertion.
• Wide Temperature Range & Compliance — Operates from −40 °C to 105 °C and is RoHS compliant.

Typical Applications

• Power-supply filtering: Low impedance and high ripple-current capability make this capacitor suitable for smoothing and filtering in DC power supplies.
• DC/DC converter output decoupling: High-frequency performance and compact size support output-stage decoupling where space is limited and ripple currents are significant.
• Industrial control electronics: Long endurance at 105 °C and robust leakage/tan δ characteristics support reliable operation in demanding environments.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 810 mA (120 Hz) and 1.62 A (10 kHz) reduce heating and extend service life under AC stress.
• Effective high-frequency performance: Lower impedance at high frequency and a measured impedance of 280 mΩ help maintain voltage stability in switching environments.
• Compact footprint: φ10 × 25 mm can and 5 mm lead spacing deliver a small, board-friendly package for space-constrained designs.
• Durable operation at elevated temperature: 12,000 h endurance at 105 °C provides predictable lifetime for long-term installations.
• Predictable electrical behavior: Specified tan δ (0.09 at 20 °C, 120 Hz) and defined leakage current (176 µA) simplify thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted-substance conformity.
