UPM1E222MHD

The UPM1E222MHD is a high-reliability, low-impedance miniature aluminum electrolytic capacitor in a radial lead can. Designed for applications requiring 2.2 mF capacitance at 25 V, it combines long endurance and robust ripple-current capability in a compact φ12.5 × 40 mm package.

Targeted for demanding environments, the UPM1E222MHD supports automotive and other high-reliability power electronics where sustained performance over temperature and time is required.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 25 V and tolerance of -20% to +20%.
• Low Impedance — Rated impedance of 24 mΩ, supporting stable filtering and decoupling in power circuits.
• High Ripple Current Handling — Low-frequency ripple current 2.4089 A (120 Hz) and high-frequency ripple current 2.21 A (200 kHz) for effective ripple attenuation across frequencies.
• Long Endurance — 5000 hours load life at 105°C (endurance specified in the UPM series) for sustained operation in high-temperature applications.
• Wide Temperature Range — Operating from -55°C to +105°C to accommodate harsh thermal environments.
• Electrical Losses — tan δ (DF) of 0.16 measured at 20°C and 120 Hz for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 1650 µA after one minute at rated voltage, allowing design sizing for standby and hold-up requirements.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing (±0.5 mm). Size: φ12.5 × 40 mm (L: 4 × D: 1.25 cm).
• Automotive-Grade Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, supporting use in regulated automotive designs.
• Availability — Supplied in bulk/bag packing with status listed as mass production.

Typical Applications

• Automotive power electronics — Smoothing and decoupling in in-vehicle power circuits where 25 V ratings and high ripple capability are needed.
• Electronic control units (ECUs) — Bulk capacitance and low impedance help maintain stable supply rails under dynamic loads.
• Power converters and DC–DC modules — Supports energy storage and ripple suppression across a broad frequency range thanks to high ripple current ratings.
• Systems operating in wide temperature ranges — Suitable for applications requiring operation from -55°C to +105°C and long-term endurance at elevated temperature.

Unique Advantages

• High ripple tolerance: Measured ripple current ratings at both low and high frequencies reduce stress on upstream components and improve power-stage stability.
• Low ESR/Impedance: 24 mΩ impedance minimizes voltage drop and heat generation in high-current applications.
• Long-term reliability: 5000-hour endurance at 105°C delivers predictable lifetime performance for demanding deployments.
• Automotive readiness: AEC-Q200 qualification and RoHS compliance streamline use in regulated automotive designs.
• Compact radial package: φ12.5 × 40 mm can and 5 mm lead spacing enable straightforward through-hole mounting in space-constrained layouts.
• Clear electrical characterization: Specified tan δ, leakage current, and tolerance simplify selection and thermal budget calculations.
