UVR2E221MRD

The UVR2E221MRD is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UVR series, optimized for general-purpose and entertainment electronics applications. It provides 220 µF capacitance at a 250 V rated voltage in a compact φ20 × 40 mm can with 10 mm lead spacing.

Key performance characteristics include a dissipation factor (tan δ) of 0.2 (measured at 20°C, 120 Hz), low- and high-frequency ripple handling, a -40°C to 85°C operating range, and a rated endurance of 2000 hours at 85°C.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (120 Hz, 20°C), suitable for bulk energy storage and smoothing applications.
• Rated Voltage — 250 V DC rating for higher-voltage power rails and industrial/consumer supply lines.
• Dissipation Factor (tan δ) — 0.2 measured at 20°C, 120 Hz, enabling predictable loss behavior for filter and decoupling designs.
• Ripple Current Capability — Low-frequency ripple current of 740 mA at 120 Hz and high-frequency ripple current of 1.184 A at 10 kHz to support smoothing and decoupling across frequencies.
• Leakage Current — Specified leakage current of 2300 µA, useful for assessing standby and bias current budgets.
• Temperature & Endurance — Operating range from −40°C to +85°C with 2000 hours endurance at 85°C, aligning with continuous operation in moderate thermal environments.
• Package & Mounting — Radial lead, can-style package (φ20 × 40 mm) with 10 mm lead spacing and standard radial mounting for through-hole assembly.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit assembly flow and handling preferences.

Typical Applications

• Entertainment electronics — Power supply smoothing and bulk decoupling in audio/video equipment and consumer entertainment devices.
• General-purpose power supplies — DC link and output filtering for medium-voltage supplies where 250 V rating and high ripple handling are required.
• DC rail decoupling — Local energy storage and transient suppression on higher-voltage rails in consumer and professional electronics.

Unique Advantages

• High voltage capability: 250 V rating permits use on elevated DC rails without stacking or additional components.
• Frequency-flexible ripple performance: Specified ripple current at both 120 Hz and 10 kHz supports filtering across a wide frequency range.
• Compact, through-hole form factor: φ20 × 40 mm radial can with 10 mm lead spacing provides a space-efficient solution for PCB layouts that require through-hole mounting.
• Extended endurance at elevated temperature: 2000 hours at 85°C offers predictable lifetime behavior for continuous-duty applications.
• RoHS compliance: Meets environmental directive requirements for electronics assembly and distribution.
