UHE1C222MHD

The UHE1C222MHD is a radial lead aluminum electrolytic capacitor in Nichicon's UHE series, delivering 2.2 mF (2200 µF) of capacitance at a 16 V rated voltage. It combines a compact φ12.5 × 25 mm can with a 5 mm lead spacing for PCB-mounted, through-hole assemblies.

Designed for general-purpose power applications, the part offers low impedance, high ripple-current capability and long-term endurance up to 10,000 hours at 105°C, making it suitable for designs that require reliable bulk energy storage and filtering under elevated temperature conditions.

Key Features

• Capacitance & Tolerance — 2.2 mF (2200 µF) with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 16 V DC rating for common low-voltage power rails.
• Low Impedance — 89 mΩ impedance helps reduce voltage ripple and power dissipation in high-current circuits.
• High Ripple Current — 1.784 A at 120 Hz and 2.23 A at 10 kHz frequency points, supporting both low- and high-frequency ripple conditions.
• Low Leakage Current — Specified leakage current of 352 µA for reduced standby loss and predictable behavior in bias circuits.
• Long Endurance — Rated for 10,000 hours at 105°C when used under specified DC bias and ripple conditions, supporting sustained operation in elevated-temperature environments.
• Temperature Range — −40°C to +105°C operating range for broad environmental compatibility.
• Package & Mounting — Radial lead, aluminum can (φ12.5 × 25 mm), 5 mm lead spacing (±0.5 mm); available in bulk or bag packing for production handling.
• Dissipation Factor (tan δ) — 0.18 (measured at 20°C, 120 Hz), providing a verified loss characteristic for design calculations.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply smoothing — Bulk energy storage and ripple filtering on low-voltage DC rails, leveraging 2200 µF capacitance and low impedance to improve voltage stability.
• DC/DC converter output filtering — Supports converter output stages that require high ripple current handling at both low and high frequencies.
• Industrial and consumer equipment — Suited for PCB-mounted power sections that must operate reliably across −40°C to +105°C with extended endurance.
• Backup and hold-up circuits — Provides compact charge storage with predictable leakage and long life for short-term hold-up requirements.

Unique Advantages

• High ripple tolerance: Rated ripple currents at 120 Hz and 10 kHz accommodate both mains-frequency and switching-frequency ripple without exceeding specifications.
• Low ESR/Impedance: 89 mΩ impedance reduces heat generation and helps maintain voltage regulation under load.
• Extended high-temperature endurance: 10,000-hour life at 105°C supports long-term reliability in warm operating environments.
• Compact radial package: φ12.5 × 25 mm can with 5 mm lead spacing minimizes PCB footprint while remaining easy to mount in through-hole assemblies.
• Predictable leakage and loss characteristics: Specified leakage current (352 µA) and tan δ (0.18) make electrical behavior straightforward to model in designs.
• RoHS compliant and production-ready: Meets RoHS requirements and is available in bulk or bag packing for volume assembly.
