UCA2V330MHD

The UCA2V330MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UCA series, designed for compact high-voltage applications. It delivers 33 µF at a 350 V rating in a φ16×20 mm can, offering high ripple capability and extended load life for power supply and ballast circuits.

Built for general-purpose high-voltage smoothing and decoupling, this polarized capacitor combines a small footprint with specified high-frequency ripple performance and a long endurance rating at elevated temperature.

Key Features

• Capacitance & Voltage: 33 µF nominal capacitance rated for 350 V DC, with a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High ripple current capability: Rated ripple current of 600 mA at 105°C/100 kHz and 300 mA at 120 Hz, enabling robust performance under high-frequency ripple loads.
• Long operating life: Specified endurance of 12,000 hours at 105°C under D.C. bias plus rated ripple current (series-level specification).
• Temperature range: Operating from −25°C to +105°C to support higher-temperature environments within the specified range.
• Electrical loss and leakage: Tangent of loss angle (tan δ) up to 0.20 (measured at 120 Hz, 20°C) and a measured leakage current of 562 µA at 20°C after 1 minute.
• Compact radial package: φ16×20 mm case with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Packaging & identification: Supplied in bulk with no terminal forming; marked with white lettering on a dark brown sleeve. RoHS compliant.

Typical Applications

• Power supplies: Smoothing and ripple filtering in high-voltage power-supply stages where compact, high-voltage capacitance is required.
• Ballast circuits: Designed for ballast applications requiring sustained ripple handling and long life at elevated temperatures.
• General-purpose high-voltage circuits: Decoupling and energy-storage roles in through-hole assemblies where radial-lead mounting and a small footprint are needed.

Unique Advantages

• High-frequency ripple handling: 600 mA rating at 100 kHz supports applications with significant high-frequency ripple currents.
• Extended endurance at elevated temperature: 12,000-hour rated life at 105°C provides predictable long-term performance under load.
• Space-efficient footprint: φ16×20 mm can and 7.5 mm lead spacing deliver a compact solution for through-hole designs.
• Clear electrical characterization: Specified tan δ and measured leakage current allow straightforward selection and margining in design.
• RoHS compliant and identifiable: Environmental compliance and white-on-dark-brown sleeve marking simplify inventory and regulatory handling.
