UCA2G330MHD

The UCA2G330MHD is a miniature radial‑lead aluminum electrolytic capacitor designed for high ripple current and long operational life in power circuits. It is a polarized, radial can package (φ16×25 mm) optimized for power supply and ballast applications where compact size, high voltage capability and endurance are required.

Key value comes from its 400 V rating, 33 µF capacitance, high ripple handling at high frequency, and long rated life of 12,000 hours at 105°C, making it suitable for demanding DC filter and ballast duties in general‑purpose industrial designs.

Key Features

• Electrical Performance — 33 µF capacitance at a 400 V rating with a capacitance tolerance of ±20% (120 Hz, 20°C), suitable for high‑voltage DC filtering.
• High Ripple Current Capability — Rated ripple current up to 640 mA at 100 kHz (640 mA high‑frequency rating; 320 mA at 120 Hz), enabling robust performance under AC ripple and switching converter loads.
• Low Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.20 (measurement at 120 Hz, 20°C for 400 V rating), supporting stable AC performance in filtering roles.
• Leakage Current — Specified leakage current of 628 µA (after 1 minute at 20°C), sized for predictable DC bias behavior in power applications.
• Compact Radial Can Package — φ16×25 mm case with 7.5 mm lead spacing and radial lead mounting; bulk packaged with no terminal forming for straightforward through‑hole assembly.
• Wide Operating Range and Long Life — Rated for −25°C to +105°C operating temperature and a load life of 12,000 hours at 105°C, designed for long‑term durability in harsh thermal environments.
• Environmental Compliance — RoHS‑compliant construction per the product specification.

Typical Applications

• Power Supplies — DC link and output filtering where 400 V rating and high ripple capability improve stability and decoupling under switching loads.
• Ballast Circuits — AC/DC ballast applications requiring compact, high‑voltage filtering components with long operational life.
• General‑Purpose Power Filtering — Bulk and smoothing applications in industrial electronics that require a polarized, high‑voltage capacitor in a radial can package.

Unique Advantages

• High Voltage and Compact Footprint — 400 V rating in a φ16×25 mm can enables high‑voltage designs without excessive board area.
• Designed for High Ripple Environments — 640 mA ripple at 100 kHz supports modern switching power architectures and reduces thermal stress on the capacitor.
• Extended Life at Elevated Temperature — 12,000 hours at 105°C provides predictable long‑term capacitance retention and reliability in elevated ambient conditions.
• Consistent Loss and Leakage Characteristics — Specified tan δ and leakage current figures allow accurate circuit margining and predictable performance under bias.
• Through‑Hole Radial Packaging — Standard radial lead spacing (7.5 mm) and bulk packaging simplify assembly for repairable or prototyping workflows.
• Regulatory Compliance — RoHS compliance supports use in regulated product lines and simplifies environmental documentation.
