UCYW6220MHD

The UCYW6220MHD is a radial-lead aluminum electrolytic capacitor from the Nichicon UCY series designed for high-voltage, high-ripple applications. It combines a 22 µF capacitance with a 420 V rated voltage, a compact φ12.5 × 20 mm can and 5 mm lead spacing for through-hole mounting.

Engineered for long life and elevated-temperature operation, this capacitor supports demanding power-supply and ballast applications and is AEC-Q200 qualified with RoHS compliance for regulated production environments.

Key Features

• Capacitance and Tolerance — 22 µF with ±20% tolerance at 120 Hz, 20°C, suitable for smoothing and energy-storage roles in high-voltage circuits.
• High Voltage Rating — 420 V rated voltage for use on higher-voltage DC rails.
• High Ripple Current Capability — Low-frequency ripple current 285 mA (120 Hz) and high-frequency ripple current 570 mA (100 kHz), supporting substantial AC ripple handling in power stages.
• Long Endurance — Designed for 10000 hours of life at 105°C under rated conditions, providing extended operational reliability in elevated-temperature environments.
• Temperature Performance — Operating range from −40°C to +105°C, covering a wide set of environmental conditions.
• Loss Characteristics — tan δ (DF) of 0.24 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics for thermal and performance planning.
• Leakage Current — Specified leakage current of 469.6 µA for initial screening and design margin calculations.
• Package and Mounting — Radial lead (can-type) package, size φ12.5 × 20 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant for applications requiring recognized reliability standards and environmental compliance.

Typical Applications

• Power Supplies — Bulk energy storage and smoothing on high-voltage DC rails where 420 V rating and high ripple capability are required.
• Ballasts and Lighting — Filtering and energy buffering in ballast circuits that demand reliable high-voltage capacitors with long life at elevated temperatures.
• Automotive Electronics — Use in automotive-grade systems that benefit from AEC-Q200 qualification and an operating temperature range of −40°C to +105°C.
• Industrial Power Conversion — DC link and filtering duties in converters and inverters where elevated ripple current handling and long endurance improve system robustness.

Unique Advantages

• High-Voltage Capability: 420 V rating enables design on higher-voltage DC buses without series stacking.
• Robust Ripple Handling: Specified ripple currents of 285 mA (120 Hz) and 570 mA (100 kHz) support demanding AC loading and reduce thermal stress in operation.
• Extended High-Temperature Life: 10000 hours at 105°C provides predictable longevity in thermally challenging applications.
• AEC-Q200 Qualification: Recognized reliability screening for applications requiring automotive/industrial stress qualifications.
• Compact Through-Hole Form Factor: φ12.5 × 20 mm radial-can package with 5 mm lead spacing fits space-constrained PCB designs while keeping through-hole mechanical robustness.
• Regulatory Compliance: RoHS compliant to support environmental and regulatory requirements in production designs.
