UVR2G221MRD

The UVR2G221MRD is a miniature aluminum electrolytic capacitor from Nichicon’s UVR series, configured as a radial-lead, polarized can. Designed for general-purpose and entertainment-electronics applications, it pairs a 220 µF capacitance with a 400 V rated voltage for high-voltage circuit requirements.

It delivers application-focused electrical characteristics—including defined ripple current ratings, leakage current, and endurance—within a compact φ25 × 50 mm can and 12.5 mm lead spacing for through-hole assemblies.

Key Features

• Capacitance & Tolerance — 220 µF nominal with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 400 V DC rated voltage for high-voltage circuit segments.
• Radial Lead Package — Through-hole radial-lead can with φ25 × 50 mm body size and 12.5 mm lead spacing (±0.5 mm) for straightforward PCB mounting and replacement designs.
• Ripple Current Ratings — Low-frequency ripple current of 750 mA at 120 Hz and high-frequency ripple current of 1.2 A at 10 kHz to support AC ripple handling across different operating frequencies.
• Leakage Current — Specified leakage current of 3,620 µA after rated-voltage application conditions.
• Loss Tangent (tan δ) — tan δ = 0.25 (measured at 20°C, 120 Hz), providing a defined dissipation characteristic for design calculations.
• Operating Temperature & Endurance — Operating range from −40°C to +85°C with an endurance rating of 2,000 hours at 85°C under rated voltage conditions.
• Compliance & Packaging — RoHS-compliant; supplied in bulk (no terminal forming) or bag packing to suit production and prototyping requirements.

Typical Applications

• Entertainment Electronics: Suited to general-purpose capacitor requirements in consumer entertainment equipment where the UVR series is specified.
• General-Purpose Electronic Circuits: Intended for use in general-purpose assemblies that require a 220 µF, 400 V polarized electrolytic solution.
• Through-Hole PCB Assemblies: Used where a radial-lead can with 12.5 mm lead spacing and compact φ25 × 50 mm sizing is required for through-hole mounting or replacement parts.

Unique Advantages

• 400 V Rated Capability: Enables designers to implement this capacitor in circuits requiring a 400 V DC rating without up-rating components.
• Defined Ripple Performance: Published low- and high-frequency ripple current ratings (750 mA @ 120 Hz; 1.2 A @ 10 kHz) allow accurate thermal and reliability planning.
• Compact Radial Can: Miniature φ25 × 50 mm body with standard 12.5 mm lead spacing simplifies mechanical integration into through-hole boards.
• Measured tan δ and Leakage: Specified tan δ (0.25 at 20°C, 120 Hz) and a defined leakage current value provide predictable electrical behavior for circuit simulations and validation.
• Endurance at Elevated Temperature: 2,000-hour life at 85°C under rated voltage supports lifetime planning for designs operated in warmer environments.
• RoHS Compliance: Meets RoHS directive requirements for lead-restricted designs and regulatory conformity.
