UVR1A220MDD

The UVR1A220MDD is a miniature aluminum electrolytic capacitor from Nichicon's UVR series. It is a standard radial-lead, polarized electrolytic designed for general-purpose use and entertainment electronics requiring a compact, through-hole capacitor.

Key attributes include a 22 µF capacitance at 10 V, a compact φ5 × 11 mm can, low leakage and measurable ripple handling at both low and high frequencies. Note: Current product status — End Of Life.

Key Features

• Electrical Performance — 22 µF capacitance at a rated voltage of 10 V with tolerance −20% to +20% and a tangent of loss angle (tan δ) of 0.24 measured at 20°C, 120 Hz (10 V).
• Ripple Current Handling — Low-frequency ripple current 65 mA at 120 Hz and high-frequency ripple current 130 mA at 10 kHz, enabling decoupling and smoothing tasks across frequency ranges.
• Low Leakage — Specified leakage current of 6.6 µA after rated-voltage application, supporting low-standby and stable-bias applications.
• Reliability / Endurance — Endurance rating of 2000 hours at 85°C with specified limits on capacitance change, tan δ and leakage after recovery to 20°C.
• Compact Radial Package — Miniature φ5 × 11 mm aluminum can with radial leads; lead spacing 2.0 mm (±0.5 mm) for straightforward through-hole placement and handling. Packaging available in bulk or bag.
• Operating Temperature — Specified for −40°C to +85°C operation, matching the UVR series category temperature range for this voltage class.
• RoHS Compliance — Compliant with applicable RoHS directives.

Typical Applications

• Consumer and Entertainment Electronics — Small form-factor energy storage and smoothing in audio, video and other consumer entertainment circuitry where compact radial electrolytics are required.
• General-Purpose Power Rail Support — Local decoupling and smoothing on low-voltage DC rails in general electronic assemblies.
• Compact Through-Hole Designs — Use in space-constrained boards requiring a miniature polarized capacitor with radial leads.

Unique Advantages

• Compact footprint: A φ5 × 11 mm can delivers 22 µF capacitance in a small through-hole package for tight layouts.
• Dual-frequency ripple capability: Rated ripple currents at 120 Hz and 10 kHz provide quantified performance for both low- and high-frequency ripple conditions.
• Low leakage performance: 6.6 µA leakage current supports circuits where low bias leakage is important.
• Proven endurance: 2000-hour life at 85°C delivers predictable aging behavior for long-term designs.
• Through-hole mounting simplicity: Radial lead format with defined 2.0 mm lead spacing simplifies manual assembly and wave-solder-compatible workflows.
• Regulatory compliance: RoHS compliance supports environmentally restricted designs.
