UVR0J221MDD

The UVR0J221MDD is a miniature aluminum electrolytic capacitor in a radial-lead can, offering 220 µF capacitance at a 6.3 V rating. Designed as part of Nichicon’s UVR series, this component targets general-purpose and entertainment-electronics applications where compact size and reliable performance are required.

Key attributes include a compact φ5 × 11 mm package, a –40 °C to 85 °C operating range, 2,000 hours endurance at 85 °C, measurable ripple-current capability, and RoHS compliance—making it suitable for space-constrained power-filtering and decoupling roles in consumer equipment.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%, providing predictable energy storage for low-voltage circuits.
• Miniature Radial Package — Compact radial can with dimensions φ5 × 11 mm and 2 mm lead spacing (±0.5 mm), enabling use in tight PCB layouts.
• Temperature Range — Rated for operation from −40 °C to 85 °C to cover a wide span of consumer and general-purpose environments.
• Endurance — Specified life of 2,000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage current after the endurance test.
• Ripple Current Capability — Low-frequency ripple current 200 mA (120 Hz) and high-frequency ripple current 300 mA (10 kHz), suitable for smoothing in low-voltage supplies.
• Low Leakage & Loss — Measured leakage current 41.58 µA (per part data) and tan δ of 0.28 at 20 °C, 120 Hz, supporting stable performance in DC-biased circuits.
• Polarized Design — Polarized electrolytic construction for standard DC filtering applications.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• RoHS Compliant — Meets RoHS requirements as stated in the product and series data.

Typical Applications

• Entertainment Electronics — Part of the UVR standard series for entertainment electronics; compact form and 220 µF capacitance suit power filtering and decoupling in consumer A/V devices.
• General-Purpose Consumer Electronics — Useful for small, low-voltage modules where space is limited and predictable capacitance, leakage, and ripple performance are required.
• Compact Power Supply Modules — The combination of 6.3 V rating, ripple-current capability, and miniature package supports smoothing and local energy storage on compact PCBs.

Unique Advantages

• Space-efficient energy storage: The φ5 × 11 mm radial can delivers 220 µF capacitance in a small footprint, simplifying placement in space-constrained designs.
• Measured ripple handling: Specified low- and high-frequency ripple current ratings (200 mA @120 Hz, 300 mA @10 kHz) help designers evaluate thermal and ripple performance precisely.
• Defined endurance behavior: 2,000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage supports predictable lifetime planning.
• Low leakage and loss angle: Part-level leakage current and tan δ data enable straightforward estimation of standby and loss characteristics in DC circuits.
• Radial-lead convenience: 2 mm lead spacing and standard radial can format ease manual assembly and through-hole PCB integration.
• Regulatory compliance: RoHS compliance reduces material-conformance risk for consumer and commercial equipment.
