UPA1E222MHD6

The UPA1E222MHD6 is a Nichicon UPA series aluminum electrolytic capacitor in a radial can package, designed for compact switching power supply and general-purpose power applications. It delivers a 2.2 mF capacitance at 25 V with a low-impedance construction intended to improve ripple handling and transient performance in power circuits.

Built for high-reliability use, the part is rated for operation from −55°C to +105°C and a specified lifetime of 5000 hours at 105°C. Its small can size and radial lead form factor make it suitable for through-hole assemblies where board space and power performance must be balanced.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 25 V with a tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 52 mΩ, supporting improved ripple suppression and lower voltage drop under load.
• High Ripple Current — Rated ripple current of 1.98 A at 120 Hz and 2.33 A at 10 kHz for effective handling of switching currents.
• Temperature & Endurance — Operating temperature range −55°C to +105°C and a rated lifetime of 5000 hours at 105°C.
• Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and physical size L: 2.0 cm × D: 1.6 cm for compact through-hole designs.
• Polarized, General-Purpose — Polarized aluminum electrolytic suitable for a range of power-smoothing and bulk-storage roles.
• Leakage & Loss Characteristics — Leakage current after 1 minute at 20°C is ≤ 0.03CV or 4 μA (whichever is greater); tangent of loss angle (tan δ) for 25 V units is specified in the series datasheet.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple capability reduce output ripple and improve regulation.
• DC‑DC Converters — Local energy storage and decoupling on high-density converter boards to support transient loads.
• Industrial Power Modules — Compact through-hole power modules that require reliable performance across −55°C to +105°C operating range.
• General-Purpose Electronics — Power smoothing and bulk capacitance in consumer and professional electronic equipment.

Unique Advantages

• Compact footprint with high capacitance: 2.2 mF in a 2.0 cm × 1.6 cm can minimizes board area while providing substantial bulk energy storage.
• Low-impedance construction: 52 mΩ impedance helps reduce voltage ripple and improve transient response in switching environments.
• High-frequency ripple capability: Rated ripple currents at both 120 Hz and 10 kHz support performance across switching and lower-frequency domains.
• Long life at elevated temperature: 5000 hours at 105°C provides a measurable reliability metric for demanding thermal environments.
• Through‑hole robustness: Radial lead and standard 7.5 mm spacing simplify insertion and soldering for traditional PCB assembly processes.
• RoHS compliant: Meets the RoHS directive as noted in the product information.
