UCA2G470MHD

The UCA2G470MHD is a miniature, polarized aluminum electrolytic capacitor designed for high-voltage DC applications. It combines a 400 V rating with 47 µF capacitance in a compact radial can (φ16 × 30.5 mm) and is optimized for high ripple-handling and long operational life.

Targeted at power-supply and ballast applications as well as general-purpose high-voltage filtering, the UCA2G470MHD delivers high ripple current capacity and a rated lifetime of 12,000 hours at 105°C. It is RoHS compliant and supplied in bulk with no terminal forming.

Key Features

• Capacitance & Voltage: 47 µF capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Capability: Rated ripple current up to 840 mArms at 105°C / 100 kHz and 420 mA at 120 Hz for demanding DC filtering and power conversion use.
• Long Operational Life: Rated for 12,000 hours at 105°C under DC bias plus rated ripple current to support sustained high-temperature operation.
• Electrical Losses: Tangent of loss angle (tan δ) specified at 0.20 (measurement frequency: 120 Hz, 20°C) for the 400 V rating.
• Leakage Current: Specified leakage current of 852 µA (after 1 minute application at 20°C for this part number).
• Compact Radial Package: Case size φ16 × 30.5 mm (L: 3.05 × D: 1.6 cm) with 7.5 mm lead spacing and radial can construction for through-hole mounting.
• Environmental Compliance & Packaging: RoHS compliant and supplied in bulk packaging with no terminal forming.
• Polarized, General Purpose: Polarized aluminum electrolytic suitable for general-purpose high-voltage DC circuits.
• Obsolescence Notice: This product is scheduled to be discontinued and is not recommended for new designs.

Typical Applications

• Power Supplies: High-voltage DC smoothing and bulk energy storage where 400 V rating and high ripple capability are required.
• Ballast Circuits: Filtering and energy buffering in ballast or lamp-driver applications that operate at elevated temperatures.
• General-Purpose High-Voltage Filtering: Decoupling and ripple suppression in industrial power electronics and high-voltage assemblies.

Unique Advantages

• High-Voltage, Compact Form Factor: 400 V rating in a φ16 × 30.5 mm radial can enables high-voltage designs in constrained PCB real estate.
• Designed for High Ripple Environments: 840 mArms at 100 kHz (105°C) rating helps manage AC stress in modern switching supplies and high-frequency circuits.
• Extended High-Temperature Lifetime: 12,000 hours at 105°C under rated conditions provides predictable endurance in thermally demanding installations.
• Clear Electrical Parameters: Specified tan δ (0.20) and measured leakage current (852 µA) allow straightforward thermal and leakage budgeting in designs.
• RoHS Compliant: Meets RoHS requirements for restricted substances while being offered in bulk for high-volume assembly processes.
• Through-Hole Radial Mounting: Robust radial leads with 7.5 mm spacing simplify insertion and soldering for conventional assembly flows.
