UCA2G470MHD6

The UCA2G470MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. As a miniature, polarized can-type capacitor it delivers 47 µF at 400 V in a compact radial package suited for power conversion and ballast circuits.

Engineered for continuous operation in demanding thermal environments, this part combines long operational life with elevated ripple-handling capability, making it suitable for general-purpose high-voltage filtering and energy-buffering tasks in industrial and power-supply equipment.

Key Features

• Capacitance & Voltage — 47 µF rated at 400 V provides energy storage and smoothing for high-voltage circuits.
• High Ripple Current — Rated ripple current of 420 mA at 120 Hz and 840 mA at 100 kHz to support both low- and high-frequency filtering needs.
• Long Operational Life — Load-life specification of 12,000 hours at 105 °C for prolonged service in elevated-temperature environments.
• Temperature Range — Operating range from −25 °C to +105 °C to accommodate a wide variety of ambient conditions.
• Radial Lead, Compact Can — Radial lead mounting with 7.5 mm lead spacing and package dimensions L: 2.5 × D: 1.8 cm for space-conscious designs.
• Polarized Design & Tolerance — Polarized electrolytic construction with capacitance tolerance of −20% to +20% (±20%).
• RoHS Compliant — Meets RoHS requirements for environmental regulatory compliance.

Typical Applications

• Power Supplies — Smoothing and energy storage in high-voltage power-supply rails where high ripple handling and 400 V rating are required.
• Ballast Circuits — Energy buffering and ripple filtering in lighting ballast and related power-conditioning circuits.
• High-Frequency Filtering — Use in switching regulator output stages or filter networks where elevated ripple at 100 kHz must be managed.
• General-Purpose High-Voltage Electronics — Voltage filtering and decoupling in industrial and electronic equipment operating within the specified temperature range.

Unique Advantages

• Designed for Elevated Ripple Loads: Specified ripple ratings at both 120 Hz and 100 kHz enable confident selection for low- and high-frequency power systems.
• Durability at High Temperature: 12,000-hour life rating at 105 °C supports long-term reliability in continuous-duty, high-temperature applications.
• Compact Radial Package: Small can dimensions and 7.5 mm lead spacing simplify board layout and enable higher density in constrained assemblies.
• Clear Electrical Specification: 47 µF at 400 V with ±20% tolerance provides predictable performance for margin-conscious designs.
• Regulatory Compliance: RoHS compliance supports regulatory needs for commercial and industrial products.
