UHE1A222MPD

The UHE1A222MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHE series, designed for general-purpose electronic applications. It combines a 2200 µF capacitance with a 10 V rating in a compact φ10 × 30.5 mm can, delivering low impedance and long-term reliability in a small footprint.

Key value propositions include low impedance, high ripple-current capability, and extended endurance at elevated temperature, making it suitable where durable bulk capacitance and stable performance are required.

Key Features

• Capacitance & Rated Voltage — 2200 µF capacitance with a 10 V rated voltage and a tolerance of −20% to +20%, specified at 20°C, 120 Hz.
• Low Impedance — Specified impedance of 120 mΩ, supporting effective low-impedance energy storage in compact assemblies.
• High Ripple Current Capacity — Rated ripple current of 1.528 A at 120 Hz (low frequency) and 1.91 A at 10 kHz (high frequency), with frequency coefficients defined in the UHE series datasheet.
• Long Endurance — Life rating of 6000 hours at 105°C for this case size and voltage, with capacitance, tanδ and leakage current limits defined after endurance testing.
• Thermal Range — Operates over −40°C to +105°C ambient, supporting applications with wide temperature swings.
• Controlled Loss Characteristics — Dissipation factor (tanδ) of 0.21 measured at 20°C, 120 Hz for this part; datasheet provides rated tanδ limits by voltage.
• Low Leakage Current — Typical leakage current specified as 220 µA after voltage application at 20°C.
• Radial Can Package — φ10 × 30.5 mm radial can with 5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• RoHS Compliant & Production Ready — RoHS-compliant construction and mass-production status for supply continuity.

Unique Advantages

• Compact bulk capacitance: 2200 µF in a φ10 can delivers significant capacitance density for space-constrained designs.
• Low-impedance performance: 120 mΩ impedance helps reduce voltage ripple and maintain stable supply rails under load.
• Broad ripple handling: High ripple current ratings at both low and high frequencies allow use across a range of switching and linear supply conditions.
• Extended high-temperature life: 6000-hour endurance at 105°C supports designs that demand long-term stability in elevated-temperature environments.
• Robust specification set: Clear, measurable parameters (tanδ, leakage current, tolerance, impedance) simplify design validation and reliability planning.
• Production-ready packaging: Bulk and bag packing options and mass-production status support fast procurement and assembly volumes.
