UCY2G470MHD

The UCY2G470MHD is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. This polarized, miniature can-type capacitor delivers 47 µF at a 400 V rating in a compact φ16 × 20 mm package with 7.5 mm lead spacing.

Engineered for demanding environments, the UCY2G470MHD combines high ripple-current capability and long endurance for power-supply, ballast and automotive use cases, while meeting AEC-Q200 qualification and RoHS requirements.

Key Features

• Capacitance and Voltage: 47 µF capacitance rated at 400 V for high-voltage smoothing and energy storage in compact circuits.
• High Ripple Current: Handles 520 mA at 120 Hz (low frequency) and 1.04 A at 100 kHz (high frequency), enabling reliable performance under AC ripple and switching conditions.
• Long Endurance: Rated life of 10,000 hours at 105 °C, providing extended service life in elevated-temperature applications.
• Temperature Range: Operates from −40 °C to +105 °C to cover a wide range of environmental conditions.
• Low Loss (tan δ): tanδ of 0.24 measured at 20 °C, 120 Hz, indicating controlled dissipation factor for stable operation.
• Leakage and Tolerance: Specified leakage current of 852 µA and capacitance tolerance of −20% to +20% for predictable performance and design margining.
• Compact Radial Package: φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting where space efficiency matters; available bulk or bag packing.
• AEC-Q200 Qualified & RoHS Compliant: Designed to meet automotive-grade reliability and environmental compliance for regulated applications.

Typical Applications

• Power Supplies: Bulk smoothing and filtering in high-voltage power-supply rails where 400 V rating and high ripple capability are required.
• Ballasts and Lighting Electronics: Energy storage and ripple handling in ballast circuits as noted in product documentation.
• Automotive Electronics: Suitable for automotive power electronics and auxiliary systems that require AEC-Q200 qualification and extended high-temperature life.
• High-Frequency Power Stages: Filtering and decoupling in switching converters and inverters where high-frequency ripple current up to 1.04 A at 100 kHz must be accommodated.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low and high frequencies reduce heating and improve reliability in switching and AC environments.
• Extended life at elevated temperature: 10,000-hour endurance at 105 °C supports longer maintenance intervals and predictable lifecycle planning.
• Automotive-grade qualification: AEC-Q200 rating provides an established reliability baseline for vehicle electronics and other demanding deployments.
• Compact, through-hole form factor: φ16 × 20 mm radial can fits constrained layouts while providing robust leaded mounting for mechanical stability.
• Regulatory compliance: RoHS compliance simplifies material selection for regulated markets.
