UPW1E222MHD

The UPW1E222MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPW series. It is a radial-lead, polarized capacitor with 2200 µF (2.2 mF) capacitance rated at 25 V, engineered for low impedance and stable performance in power electronics.

Designed for demanding power applications, this part targets switching power supplies and automotive electronic modules where sustained ripple handling, long endurance at elevated temperature, and compact packaging are required.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of -20% to +20%.
• Low Impedance — Specified impedance of 44 mΩ for reduced AC voltage drop and improved transient response in power circuits.
• High Ripple Current Capability — Rated ripple currents of 2.172 A at 120 Hz and 2.555 A at 10 kHz to support high-frequency and low-frequency ripple conditions.
• Long Endurance at Elevated Temperature — Rated for 8000 hours life at 105°C, supporting prolonged operation in hot environments.
• Wide Operating Temperature — Operational range from -55°C to +105°C for broad environmental suitability.
• Package & Mounting — Miniature radial can: diameter φ16 × length 25 mm, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Loss Characteristics — tan δ specified at 0.16 (measured at 20°C, 120 Hz) for this capacitance/voltage class to help assess ESR-related losses.
• Leakage Current — Specified leakage current of 1650 µA to support design of bias and discharge circuits.
• AEC Qualification — Ratings include AEC-Q200, reflecting suitability for applications requiring recognized component-level reliability.

Typical Applications

• Switching Power Supplies — Output smoothing and bulk energy storage where low impedance and high ripple handling improve regulation and reduce voltage ripple.
• Automotive Electronic Modules — Power filtering and decoupling in vehicle electronics, leveraging the AEC-Q200 rating and 105°C endurance.
• DC/DC Converters and Power Management — Bulk capacitance and high ripple current capability for converters in compact systems.

Unique Advantages

• High ripple-current tolerance: 2.172 A at 120 Hz and 2.555 A at 10 kHz enable reliable handling of both low- and high-frequency ripple in power rails.
• Extended high-temperature life: 8000 hours at 105°C provides predictable long-term performance in thermally demanding applications.
• Compact, serviceable package: φ16 × 25 mm radial can with 7.5 mm lead spacing offers a space-efficient solution for through-hole assemblies.
• Low impedance: 44 mΩ impedance reduces AC losses and improves transient response in power circuits.
• AEC-Q200 rated: Component-level qualification for applications that require recognized reliability standards.
• Measured electrical characteristics: Specified tan δ and leakage current values simplify thermal and discharge design considerations.
