UCYW6470MHD6

The UCYW6470MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCY series. It is a polarized, radial‑lead power capacitor rated 420 V with 47 µF capacitance and designed for demanding power applications.

Engineered for applications that require high ripple tolerance and extended life at elevated temperatures, this part combines compact φ16×25 mm packaging with long endurance and AEC‑Q200 qualification for reliable performance in harsh environments.

Key Features

• High Voltage Rating — Rated for 420 V to support high‑voltage power rails and ballast or power supply circuits.
• Capacitance and Tolerance — 47 µF nominal capacitance with a tolerance of −20% to +20% for predictable decoupling and bulk energy storage.
• High Ripple Current Capability — Low‑frequency ripple current 500 mA (120 Hz) and high‑frequency ripple current 1 A (100 kHz) to handle pulsed and switching loads.
• Long Endurance at Elevated Temperature — Rated life of 12,000 hours at +105 °C under rated conditions for extended field reliability.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.24 measured at 20 °C, 120 Hz for predictable dissipation characteristics.
• Compact Radial Package — φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through‑hole assemblies.
• AEC‑Q200 Qualified and RoHS Compliant — Meets AEC‑Q200 reliability screening and is RoHS compliant for regulated environments and higher reliability applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit assembly and handling preferences.

Typical Applications

• Power Supplies — Bulk energy storage and ripple filtering on high‑voltage DC rails in power supply designs.
• Ballasts — High‑voltage capacitance for ballast circuits where ripple endurance and high voltage rating are required.
• Automotive Power Electronics — Use in vehicle power systems where AEC‑Q200 qualification and long life at elevated temperature are needed.

Unique Advantages

• 420 V Rated for High‑Voltage Systems: Enables use on higher DC rails without series stacking or additional components.
• High Ripple Endurance: Combined 500 mA (120 Hz) and 1 A (100 kHz) ripple ratings address both low‑frequency and switching‑frequency stress.
• Extended High‑Temperature Life: 12,000 hours at 105 °C reduces replacement and maintenance frequency in high‑heat environments.
• Compact Through‑Hole Form Factor: φ16×25 mm radial can with 7.5 mm lead spacing balances board space and capacitance for compact power modules.
• AEC‑Q200 Qualification: Provides an added level of reliability screening for applications demanding automotive‑grade durability.
• Regulatory Compliance: RoHS compliance supports use in regulated product lines and simplifies environmental compliance.
