UCY2V220MPD9

The UCY2V220MPD9 is a Nichicon UCY series aluminum electrolytic capacitor in a radial-lead can, rated 22 µF at 350 V. It combines a compact φ10 × 20 mm package with a polarized radial lead form factor for through-hole mounting.

Designed for high-ripple and long-life use, this part is suited for power supply and ballast applications and for automotive electrical systems where AEC-Q200 qualification and extended endurance are required. Key value propositions include high ripple-current capability, a 10000-hour endurance at 105 °C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 350 V and a tolerance of -20% to +20%.
• High ripple-current capability — Rated low-frequency ripple current of 215 mA (120 Hz) and high-frequency ripple current of 430 mA (100 kHz), enabling robust performance under AC-loaded conditions.
• Long endurance — Rated for 10000 hours of life at 105 °C, providing stability for extended high-temperature operation.
• Loss and leakage characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20 °C, 120 Hz, and leakage current specified at 408 µA.
• Automotive-grade qualification — AEC‑Q200 qualified, suitable for automotive electrical applications requiring that rating.
• Operating temperature — Specified for -40 °C to +105 °C operation.
• Compact radial can — φ10 × 20 mm can with 5.0 mm lead spacing (±0.5 mm), radial lead mounting, and bulk or bag packing options.
• Environmental compliance — RoHS compliant.

Typical Applications

• Power supplies — Smoothing and decoupling in high-voltage power-supply stages where a 350 V rated capacitor is required.
• Ballasts — Use in ballast circuits as noted for the UCY series, leveraging the part's high ripple-current capability and long life.
• Automotive electrical systems — Suitable for automotive applications that require AEC‑Q200 qualification and wide temperature range performance.
• High-ripple circuits — Applications that impose significant ripple stress at both low and high frequencies benefit from the specified ripple-current ratings.

Unique Advantages

• High ripple tolerance: Rated for 215 mA at 120 Hz and 430 mA at 100 kHz, allowing reliable operation under AC-loaded conditions across frequency ranges.
• Extended thermal endurance: 10000-hour life at 105 °C supports long-term use in elevated-temperature environments.
• Automotive-qualified: AEC‑Q200 qualification provides an approved path into automotive electrical designs that require that standard.
• Compact footprint: φ10 × 20 mm radial can and 5.0 mm lead spacing make it practical for space-constrained through-hole layouts.
• Measured leakage and loss specs: Specified leakage current (408 µA) and tan δ (0.24 at 20 °C, 120 Hz) give predictable electrical behavior for circuit design and margin calculations.
• Regulatory compliance: RoHS compliance supports use in regulated product lines and environmental initiatives.
