UHW0J222MPD

The UHW0J222MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized capacitor offering 2200 µF capacitance at a 6.3 V rating in a compact φ10 × 20 mm can.

Designed for general-purpose electronics that require high ripple current handling and long-term endurance in a small package, this part delivers a combination of low impedance, defined loss characteristics, and a broad operating temperature range.

Key Features

• Capacitance & Voltage — 2200 µF nominal capacitance with a rated voltage of 6.3 V and a tolerance of -20% to +20% (120 Hz, 20°C).
• Miniature Radial Package — φ10 × 20 mm can with radial lead mounting and 5 mm lead spacing (±0.5 mm), enabling compact board layouts.
• High Ripple Current — Low-frequency ripple current of 1.875 A (120 Hz) and high-frequency ripple current of 2.5 A (10 kHz), suitable where elevated AC stress is present.
• Low Impedance — Specified impedance of 60 mΩ, supporting reduced voltage drop and improved AC performance.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.23 measured at 20°C, 120 Hz for this capacitance and voltage point.
• Leakage Current — Manufacturer-specified leakage current of 138.6 µA after standard voltage application.
• High Endurance — Life rating of 10,000 hours at 105°C (when operated at rated conditions), for extended field life in elevated-temperature environments.
• Wide Operating Temperature — Suitable for -40°C to +105°C operating range.
• Compliance & Availability — RoHS-compliant and listed as in mass production; packaging available as Bulk (No Terminal Forming) or Bag Packing.

Typical Applications

• General-purpose electronics — Use where a compact, polarized electrolytic capacitor with high ripple capability and long endurance is required.
• Power filtering in compact assemblies — Applicable to circuits that need high ripple current handling in a small radial-lead package.
• High-frequency support — Suitable where lower impedance and defined high-frequency ripple current performance are important.

Unique Advantages

• High capacitance density: 2200 µF in a φ10 × 20 mm can reduces board space for bulk energy storage.
• Robust ripple handling: 1.875 A (120 Hz) and 2.5 A (10 kHz) ripple ratings support demanding AC conditions without immediate degradation.
• Low impedance: 60 mΩ impedance helps minimize voltage drop under dynamic loads and improves AC performance.
• Long life at elevated temperature: 10,000 hours at 105°C provides predictable end-of-life behavior in thermally stressed designs.
• Measured dissipation characteristic: tan δ = 0.23 (20°C, 120 Hz) gives a clear, verifiable loss parameter for design calculations.
• Production-ready supply: RoHS compliance and mass-production status simplify procurement and regulatory tracking.
