UCYW6470MHD

The UCYW6470MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series. It provides 47 µF capacitance at a 420 V rating in a compact φ12.5 × 35.5 mm can with 5.0 mm lead spacing.

Designed for applications that require high ripple handling and long operational life, this polarized capacitor targets automotive and industrial power-supply and ballast applications where elevated voltage, sustained ripple current, and extended endurance at high temperature are required.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 420 V and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Ripple Current — Low-frequency ripple current of 505 mA at 120 Hz and high-frequency ripple capability of 1.01 A at 100 kHz, enabling reliable filtering in high-stress power circuits.
• Long Endurance — Load-life rated for 12,000 hours at 105°C under DC bias plus rated ripple current (endurance conditions defined by the UCY series specifications).
• Thermal and Environmental Range — Operating temperature from −40°C to +105°C; RoHS compliant and AEC-Q200 qualified for demanding applications.
• Low Loss Characteristics — Tangent of loss angle (tan δ) of 0.24 at 120 Hz, 20°C for the 420 V rating, supporting efficient energy dissipation in AC ripple environments.
• Leakage Current — Specified leakage current consistent with UCY series limits; product data lists an example leakage of 889.6 µA under test conditions.
• Compact Radial Package — φ12.5 mm diameter by 35.5 mm length can with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.

Typical Applications

• Automotive Power Systems — Energy storage and smoothing in vehicle power electronics where high voltage and long life at elevated temperature are required.
• Power Supplies — Input/output filtering and bulk energy storage in high-voltage power-supply designs benefiting from high ripple-current capability and extended endurance.
• Ballasts and Lighting — AC ripple handling and DC-link capacitance in ballast circuits and other lighting power electronics.

Unique Advantages

• High Voltage Handling: 420 V rated voltage supports high-voltage DC-link and filtering applications without additional series components.
• Elevated Ripple Performance: Specified ripple current ratings (505 mA at 120 Hz and 1.01 A at 100 kHz) reduce thermal stress and improve reliability in high-ripple environments.
• Extended High-Temperature Life: 12,000-hour endurance at 105°C provides predictable lifetime performance for continuous-duty applications.
• AEC-Q200 Qualified: Qualification for demanding environments supports use in regulated automotive systems and other high-reliability domains.
• Small Footprint Radial Can: φ12.5 × 35.5 mm sizing with 5.0 mm lead spacing offers a compact solution for through-hole placement and robust mechanical mounting.
• Regulatory Compliance: RoHS-compliant construction simplifies environmental compliance for production programs.
