UVR2V221MRD

The UVR2V221MRD is a Nichicon miniature aluminum electrolytic capacitor in a radial-lead can designed for general-purpose use. It provides 220 µF capacitance at a 350 V rating in a compact φ22 × 50 mm package intended for applications such as entertainment and consumer electronics.

Key electrical attributes include a capacitance tolerance of −20% to +20%, a specified leakage current, defined ripple current values at low and high frequencies, and an endurance rating of 2000 hours at 85°C. The part is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 350 V rated voltage, suitable for medium‑voltage smoothing and energy storage in general-purpose circuits.
• Capacitance Tolerance — Specified tolerance of −20% to +20% at 120 Hz, 20°C, enabling predictable sizing in designs requiring nominal 220 µF values.
• Ripple Current Ratings — Low-frequency ripple current of 850 mA at 120 Hz and high-frequency ripple current of 1.36 A at 10 kHz, supporting applications with AC ripple across the capacitor.
• Loss Factor (tan δ) — tanδ specified as 0.25 (measured at 20°C, 120 Hz), useful for budgeting dielectric loss in power and filtering circuits.
• Endurance — Rated life of 2000 hours at 85°C with performance limits defined for capacitance change, tanδ, and leakage current after the endurance test.
• Mechanical & Mounting — Radial lead, polarized aluminum can with φ22 × 50 mm dimensions, 10 mm lead spacing (±0.5 mm), and bulk or bag packing options.
• Compliance — RoHS compliant; series described as a standard, miniature line suitable for entertainment electronics.
• Lifecycle Status — Product status: End Of Life. Please verify current availability before specifying into new production designs.

Typical Applications

• Consumer & Entertainment Electronics — Power supply smoothing and bulk energy storage in entertainment devices where the UVR series is positioned for standard consumer equipment.
• General-Purpose Power Supplies — Filtering and ripple management on medium-voltage rails up to 350 V using the capacitor’s rated ripple current capabilities.
• Standby & Hold-Up Circuits — Energy reserve and smoothing where a 220 µF, 350 V polarized electrolytic is required and endurance at elevated temperature is important.

Unique Advantages

• 350 V Rating for Medium-Voltage Designs — Allows direct use on higher‑voltage DC rails up to the rated voltage without additional series components.
• Measurable Ripple Handling — Specified ripple current values at both 120 Hz and 10 kHz enable designers to size the capacitor relative to expected AC ripple and switching noise.
• Defined Endurance — 2000 hours at 85°C gives a clear, test‑based expectation of long-term behavior under thermal stress for reliability planning.
• Clear Loss and Leakage Specs — Provided tanδ (0.25) and measured leakage current figure (3180 µA) let engineers budget dielectric loss and standby leakage into system power budgets.
• Compact Radial-Lead Package — φ22 × 50 mm radial can with 10 mm lead spacing and ±0.5 mm tolerance supports straightforward through‑hole mounting and replacement workflows.
• RoHS Compliance — Conforms to RoHS requirements for use in environmentally restricted product lines.
