UVR2V221MRD6

The UVR2V221MRD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVR miniature-sized series. It delivers 220 µF capacitance at a 350 V rating in a compact φ25 × 40 mm can, designed for general-purpose and entertainment electronics applications.

Engineered for polarized power circuits, this part provides defined ripple-handling performance, a wide operating temperature range, and a 2000-hour endurance at 85°C for stable operation in demanding assemblies.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 350 V working voltage suitable for high-voltage DC rails.
• Leakage & Loss — Specified leakage current 3180 µA and tanδ (loss tangent) 0.25 at 20°C, 120 Hz.
• Ripple Current Capability — 890 mA at 120 Hz (low frequency) and 1.424 A at 10 kHz (high frequency) for power-supply smoothing and decoupling.
• Endurance — 2000 hours at 85°C with capacitance change within ±20% and leakage current meeting initial specified limits after test.
• Mechanical & Mounting — Radial lead can package, size φ25 × 40 mm with 12.5 mm lead spacing (±0.5 mm), suited to through‑hole PCB mounting.
• Temperature Range — Rated for use from −40°C to +85°C.
• Packaging — Supplied in bulk (no terminal forming) or bag packing.
• RoHS Compliance — Conforms to RoHS requirements as stated for the UVR series.

Typical Applications

• Entertainment Electronics — Suitable for power smoothing and bulk energy storage in audio/video equipment and similar consumer devices.
• General Purpose Power Supplies — Use for DC bus filtering, reservoir capacitance, and decoupling on high-voltage rails.
• Industrial Electronics — Fits general-purpose control and power circuits requiring a compact 350 V polarized capacitor.

Unique Advantages

• High-voltage capability: 350 V rating supports higher-voltage DC rails without series stacking.
• Defined ripple performance: Specified low- and high-frequency ripple currents provide predictable thermal and lifetime behavior in power designs.
• Compact radial can: φ25 × 40 mm footprint with standard 12.5 mm lead spacing eases through‑hole layout and mechanical retention.
• Long endurance at elevated temperature: 2000 hours at 85°C offers measurable lifecycle characteristics for long-term planning and reliability assessments.
• Measured electrical characteristics: Specified tanδ and leakage current values allow accurate modelling of loss and standby current in designs.
• RoHS compliant: Meets environmental substance restrictions for regulated markets.
