UHE2A221MHD6

The UHE2A221MHD6 is a high-reliability, miniature aluminum electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It is part of Nichicon’s UHE series and combines a compact φ16×20L package with a 100 V rated voltage and 220 µF capacitance to support power-filtering and energy-storage needs where long life and low impedance are required.

Engineered for demanding environments, this radial-lead capacitor delivers long endurance (10,000 hours at 105°C), low dissipation (tanδ 0.08 at 20°C, 120 Hz), and measurable ripple handling across low and high frequencies—making it suitable for power supplies and industrial electronics that require robust bulk capacitance at elevated voltages.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 100 V rated voltage provides substantial energy storage for high-voltage rails and bulk-decoupling duties.
• Low Loss & Low Impedance — tanδ of 0.08 (measured at 20°C, 120 Hz) and an impedance of 380 mΩ help minimize power dissipation and heating in ripple-prone circuits.
• Ripple Current Capability — Specified ripple currents of 791 mA at 120 Hz and 1.13 A at 10 kHz support both low-frequency smoothing and higher-frequency decoupling tasks.
• Long Endurance — Life rating of 10,000 hours at 105°C under specified conditions for applications requiring extended operational lifetime.
• Operating Temperature Range — −40°C to +105°C allows deployment in a broad range of ambient conditions.
• Package & Mounting — Radial lead, can package (φ16×20L) with 7.5 mm lead spacing (±0.5 mm); offered in bulk (no terminal forming) or bag packing for flexible assembly options.
• Leakage Current — Specified leakage current of 220 µA after application of rated voltage, useful for designing bias and standby power budgets.
• RoHS Compliant — Meets RoHS requirements for materials compliance.

Typical Applications

• Power Supplies — Bulk smoothing and output filtering on high-voltage rails where 100 V rating and 220 µF capacitance reduce ripple and stabilize DC output.
• Industrial Controls — Energy storage and decoupling in control boards and power modules that demand long endurance at elevated temperatures.
• Instrumentation & Test Equipment — Stable capacitance and low dissipation for precision measurement systems that require reliable filtering over long service life.

Unique Advantages

• High-Voltage Bulk Storage: 100 V rating with 220 µF capacitance provides substantial stored energy for high-voltage circuits without moving to larger packages.
• Designed for Long Life: 10,000-hour endurance at 105°C reduces maintenance and replacement frequency in continuous-operation systems.
• Measurable Ripple Handling Across Frequencies: Specified ripple currents at both 120 Hz and 10 kHz enable designers to quantify performance for low- and high-frequency noise mitigation.
• Compact Radial Form Factor: φ16×20L can size and 7.5 mm lead spacing simplify layout in through-hole assemblies while maintaining necessary capacitance and voltage capability.
• Low Dissipation: tanδ 0.08 (120 Hz, 20°C) and 380 mΩ impedance help keep thermal rise and losses under control in high-stress applications.
