UHE1E222MHD6

The UHE1E222MHD6 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. It delivers 2200 µF capacitance at 25 V in a compact φ18 × 20 mm package and is optimized for general-purpose power applications requiring long life and low impedance.

Designed for continuous operation across a wide temperature range (‑40 °C to +105 °C) with a rated endurance of 10,000 hours at 105 °C, this part targets power supply smoothing, bulk decoupling and other embedded electronics roles where stable capacitance and ripple handling are required.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance rated for 25 V operation with ±20% tolerance, suitable for bulk energy storage and smoothing on DC rails.
• Low Impedance — Specified impedance of 67 mΩ supports low-loss power filtering and reduces voltage ripple under load.
• High Ripple Handling — Low-frequency ripple current 2.288 A (120 Hz) and high-frequency ripple current 2.86 A (10 kHz) for robust performance across switching and line-frequency conditions.
• Long Life / High Reliability — Endurance rated to 10,000 hours at 105 °C, reflecting the UHE series’ long-life design for sustained elevated-temperature operation.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.16 measured at 20 °C, 120 Hz, enabling predictable dissipation behavior in design calculations.
• Compact Radial Package — Radial lead (φ18 × 20 mm) can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB layout.
• Leakage Current — Specified leakage current 550 µA for predictable standby and bias current budgeting.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Power Supply Smoothing — Bulk decoupling and smoothing on linear or switching power supplies where 2.2 mF at 25 V reduces output ripple and supports transient loads.
• DC-DC Converters — Input/output filtering on DC-DC modules benefiting from low impedance and high ripple current capability across switching frequencies.
• Industrial Control Electronics — Energy storage and filtering in control boards and instrumentation that operate over a wide temperature range and require long-term reliability.
• General Purpose Embedded Systems — Main rail decoupling and bulk capacitance in consumer or professional electronics requiring a compact radial through-hole solution.

Unique Advantages

• Designed for Long-Term Elevated-Temperature Operation: 10,000-hour endurance at 105 °C provides predictable life expectancy for sustained high-temperature environments.
• High Ripple Capacity Across Frequencies: Clear specifications for both 120 Hz and 10 kHz ripple current let designers size capacitors for both low-frequency and switching applications.
• Low Impedance for Improved Power Quality: 67 mΩ impedance reduces voltage drop and heating, improving regulator stability and transient response.
• Compact Radial Form Factor: φ18 × 20 mm can with standard lead spacing simplifies PCB layout and supports through-hole assembly processes.
• Predictable Loss and Leakage Behavior: tan δ = 0.16 and leakage current = 550 µA enable accurate thermal and bias budgeting in system designs.
• Environmentally Compliant: RoHS compliance supports use in products bound by environmental regulations.
