UCY2V220MPD

The UCY2V220MPD is a radial‑lead, miniature aluminum electrolytic capacitor in Nichicon’s UCY series designed for high ripple current and long life. It provides 22 µF capacitance at a 350 V rating in a compact φ10 × 25 mm can with 5 mm lead spacing.

This high‑reliability unit targets demanding power applications where sustained performance at elevated temperature matters, offering a wide operating range from −40 °C to 105 °C and AEC‑Q200 qualification for applications requiring enhanced component robustness.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with ±20% tolerance and a 350 V rated voltage for high‑voltage power circuitry.
• High ripple current capability: Rated low‑frequency ripple current 255 mA at 120 Hz and high‑frequency ripple current 510 mA at 100 kHz to handle dynamic load conditions.
• Loss characteristics: tan δ (DF) 0.24 measured at 20 °C, 120 Hz for predictable dissipation behavior in filter and smoothing applications.
• Long endurance: Specified life/endurance of 12,000 hours at 105 °C, with defined post‑test limits for capacitance change, dissipation factor and leakage current per the UCY series datasheet.
• Leakage current: 408 µA (per product specification / datasheet reference), measured under the standardized test condition noted in the datasheet.
• Compact radial can package: φ10 × 25 mm body, radial lead mounting with 5 mm lead spacing (±0.5 mm), available in Bulk (no terminal forming) or Bag packing.
• Operating range and compliance: −40 °C to 105 °C operating temperature and RoHS compliant; AEC‑Q200 qualified as listed in the product data.

Typical Applications

• Power supplies: Filtering and smoothing in high‑voltage power supply rails where compact size and steady ripple handling are required.
• Ballast circuits: Designed for ballast and similar lamp‑drive applications that demand sustained ripple performance and long life at elevated temperatures.
• Automotive electronics: Suitable for automotive electronic systems that require AEC‑Q200 qualified components and stable operation across −40 °C to 105 °C.

Unique Advantages

• High ripple endurance: Dual ripple‑current ratings for low and high frequencies provide designers with predictable thermal and electrical behavior across application bandwidths.
• Long life at elevated temperature: 12,000‑hour endurance at 105 °C delivers extended service life for continuous high‑temperature operation.
• AEC‑Q200 qualification: Meets AEC‑Q200 criteria, supporting use in designs that require enhanced reliability and qualification traceability.
• Space‑efficient form factor: φ10 × 25 mm radial can offers a compact solution for high‑voltage capacitance where board space is constrained.
• Clear packaging options: Available in Bulk (no terminal forming) or Bag packing to accommodate different assembly and handling workflows.
• Regulatory compliance: RoHS compliant for designs requiring restricted‑substance conformity.
