UCYW6470MHD3

The UCYW6470MHD3 is a miniature aluminum electrolytic capacitor from Nichicon's UCY series, built as a radial lead can with polarized construction. It delivers a 47 µF capacitance at a 420 V rating and is engineered for high ripple current handling and long operational life in demanding environments.

Targeted at automotive and power-supply markets—including ballast applications—the part combines high ripple capability, AEC-Q200 qualification, and RoHS compliance to meet reliability and environmental requirements for embedded power designs.

Key Features

• Electrical Performance — 47 µF capacitance at a 420 V rated voltage with ±20% tolerance, suitable for high-voltage smoothing and energy storage.
• High Ripple Current — Rated ripple current of 480 mA at 120 Hz and 960 mA at 100 kHz supports heavy AC ripple environments and switching-power applications.
• Long Operational Life — Designed for 10000 hours of life at +105°C, providing sustained performance under elevated temperature stress.
• Wide Temperature Range — Operates from –40°C to +105°C, covering typical automotive and industrial ambient conditions.
• Automotive Reliability — AEC-Q200 qualification indicating suitability for automotive-grade applications.
• Compact Radial Package — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 20 mm × D: 18 mm) for space-constrained boards.
• Compliance — RoHS compliant to support environmental regulatory requirements.

Typical Applications

• Automotive Power Electronics — Energy smoothing and decoupling in in-vehicle power supplies and auxiliary electronics where AEC-Q200 qualification is required.
• Power Supplies — Bulk capacitance and ripple filtering for high-voltage power supplies that require robust ripple handling and long life.
• Ballasts and Lighting — Designed for ballast application use, providing stable capacitance and high ripple endurance under continuous AC stress.

Unique Advantages

• High ripple-handling capability: Specified ripple currents at 120 Hz and 100 kHz (480 mA and 960 mA) enable reliable operation in both low- and high-frequency environments.
• Compact footprint with radial leads: Small can dimensions (20 × 18 mm) and 7.5 mm lead spacing simplify integration into dense PCB layouts.
• Long life at elevated temperature: 10000 hours at +105°C supports sustained use in high-temperature operating conditions.
• Automotive-grade qualification: AEC-Q200 rating provides confidence for use in vehicle systems requiring industry-recognized reliability standards.
• Wide operating range: –40°C to +105°C operational capability covers a broad set of industrial and automotive ambient conditions.
• Regulatory compliance: RoHS compliance helps meet environmental and supply-chain requirements.
