UVR2E221MRD6

The UVR2E221MRD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UVR series. It provides 220 µF capacitance at a 250 V rating in a compact can-style radial package suitable for through-hole mounting.

Designed for general-purpose and entertainment electronics applications, this capacitor combines a compact φ22 × 30 mm footprint with rated performance characteristics including ripple current capability, defined leakage, and a 2000-hour endurance at 85°C—making it suitable where reliable power filtering and bulk energy storage are required.

Key Features

• Capacitance & Voltage: 220 µF capacitance rated at 250 V, offering mid-range energy storage for higher-voltage circuits.
• Package & Mounting: Radial-lead aluminum can with dimensions φ22 × 30 mm and 10 mm lead spacing (±0.5 mm), optimized for through-hole PCB layouts.
• Temperature Range & Endurance: Operates from −40°C to +85°C with a rated endurance of 2000 hours at 85°C.
• Ripple Current Handling: Low-frequency ripple current 820 mA (120 Hz) and high-frequency ripple current 1.312 A (10 kHz) to handle dynamic loads and smoothing tasks.
• Leakage Current & Loss Angle: Specified leakage current of 2300 µA and tanδ of 0.2 (measured at 20°C, 120 Hz), enabling predictable loss and leakage behavior in designs.
• Tolerance & Polarization: Capacitance tolerance ±20% and polarized construction for correct orientation in DC circuits.
• Packaging Options & Compliance: Available in bulk (no terminal forming) or bag packing. Series is RoHS compliant and part of Nichicon's UVR miniature-sized lineup targeted at entertainment electronics.

Typical Applications

• Entertainment Electronics: Bulk energy storage and smoothing in audio, video and consumer entertainment power supplies where the UVR series is specified.
