UPA1E222MHD

The UPA1E222MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPA series, optimized for miniature, low-impedance power applications. It delivers 2200 µF capacitance at a 25 V rating and is designed for use in switching power supplies and general-purpose power filtering where high ripple capability and long life are required.

With a compact φ12.5 × 30.5 mm can, 5 mm lead spacing and long endurance at elevated temperature, this capacitor addresses space-constrained designs that demand stable performance over extended operating periods.

Key Features

• High Capacitance, Rated Voltage — 2200 µF (2.2 mF) nominal capacitance at a 25 V rating for bulk energy storage and smoothing on power rails.
• Low Impedance — Specified impedance of 36 mOhm for improved ripple handling and reduced voltage drop under AC conditions.
• High Ripple Current Capability — Low-frequency ripple current of 2.312 A (120 Hz) and high-frequency ripple current of 2.72 A (10 kHz) to support demanding switching and decoupling applications.
• Long Endurance at Elevated Temperature — Rated for 5000 hours at 105°C (φ12.5 case), enabling extended field life in thermally stressed environments.
• Wide Operating Temperature Range — −55°C to +105°C suitable for a broad range of industrial and consumer electronics conditions.
• Low Loss — Tangent of loss angle (tan δ) 0.16 measured at 20°C, 120 Hz for the 25 V variant, supporting efficient AC performance.
• Polarized Radial-Lead Package — Radial can package (φ12.5 mm diameter, 30.5 mm length) with 5 mm lead spacing for through-hole assembly; available in bulk or bag packing.
• RoHS Compliant — Meets RoHS requirements for environmental regulatory compliance.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple current capability reduce voltage ripple.
• DC-DC Converters and Power Rails — Energy storage and decoupling on intermediate and output stages to maintain voltage stability under dynamic loads.
• General-Purpose Industrial Electronics — Power conditioning and filtering in industrial control, instrumentation, and other general-purpose power circuits.

Unique Advantages

• Robust Ripple Handling — Specified ripple currents at both low and high frequencies (2.312 A at 120 Hz, 2.72 A at 10 kHz) help designers size capacitors to match switching frequencies and improving reliability.
• Compact, Space-Conscious Form — φ12.5 × 30.5 mm can with 5 mm lead spacing provides high capacitance in a small radial package for space-limited PCBs.
• Extended High-Temperature Life — 5000-hour rated endurance at 105°C for the φ12.5 case supports long-term operation in thermally demanding environments.
• Predictable Electrical Performance — Low impedance (36 mOhm) and specified tan δ help engineers predict AC behavior and reduce iterative testing.
• Design-Friendly Tolerances and Packaging — ±20% capacitance tolerance and polarized radial-lead mounting simplify BOM selection and assembly; available in bulk or bag packing to suit production needs.
• Regulatory Compliance — RoHS compliance reduces regulatory overhead for product development and deployment.
