UCA2C330MPD

The UCA2C330MPD is a miniature, radial-lead aluminum electrolytic capacitor rated 33 µF at 160 V, designed for general-purpose power applications where compact size and high ripple capability are required. It combines a 10 mm diameter × 20 mm length can with a 5 mm lead spacing and polarized radial-lead packaging.

Key value comes from its high ripple current capability (565 mA at 105 °C / 100 kHz and 282.5 mA at 120 Hz), long life (10,000 hours at 105 °C), and RoHS compliance, making it suitable for power-supply filtering and ballast applications that demand sustained performance in elevated temperatures.

Key Features

• Electrical Performance — 33 µF nominal capacitance at a rated voltage of 160 V with ±20% tolerance; polarized design for DC filtering and energy storage roles.
• High Ripple Current — Rated ripple current of 565 mA at 105 °C / 100 kHz and 282.5 mA at 120 Hz to support high-frequency and low-frequency power applications.
• Long Life & Endurance — Rated for 10,000 hours at 105 °C under load, with specified limits for capacitance change, tan δ, and leakage after life testing.
• Temperature Range — Operational across –25 °C to +105 °C for applications exposed to elevated operating temperatures.
• Compact Radial Package — 10 mm diameter × 20 mm length aluminum can with 5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting.
• Low Leakage — Static leakage current specified (311.2 µA measured for this part) and defined by datasheet limits to aid in predictable bias behavior.
• Marking & Packaging — White lettering on a dark brown sleeve; shipped in bulk with no terminal forming for convenient through-hole assembly handling.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Power Supplies — Bulk or decoupling capacitor in medium-voltage DC power supplies where 160 V rating and high ripple handling improve ripple suppression at elevated temperatures.
• Ballasts — Filtering and energy storage in ballast circuits that require stable performance over long operating lifetimes at up to 105 °C.
• General-Purpose Filtering — Through-hole radial capacitor for smoothing, DC link, or general filtering in industrial and commercial electronic equipment.

Unique Advantages

• High ripple current capability: 565 mA at 105 °C / 100 kHz supports demanding AC ripple environments and high-frequency switching supplies.
• Extended operational life: 10,000‑hour rating at 105 °C contributes to predictable long-term performance and reduced maintenance cycles.
• Compact footprint: 10 mm × 20 mm can with 5 mm lead spacing delivers high-voltage and high-ripple performance in a small through-hole package.
• Predictable leakage behavior: Specified leakage (311.2 µA) and datasheet leakage formula help with bias planning and low-current designs.
• Clear identification and handling: White lettering on a dark brown sleeve and bulk packaging simplify assembly and inventory handling.
• RoHS compliance: Environmentally compliant for integration into designs requiring restricted substance adherence.

Why Choose UCA2C330MPD?

The UCA2C330MPD is positioned for engineers who need a compact, through-hole aluminum electrolytic capacitor that balances high-voltage capability (160 V), substantial ripple handling, and long operational life at elevated temperatures. Its combination of rated ripple current, extended 10,000‑hour endurance at 105 °C, and predictable leakage makes it suitable for robust power-supply filtering and ballast applications.

This part is a practical choice for designs that prioritize thermal endurance and steady performance in a small radial-can package, providing long-term value through reduced maintenance and consistent behavior across the specified –25 °C to +105 °C operating range.
