UCP2G330MPD

The UCP2G330MPD is a Nichicon UCP series miniature aluminum electrolytic capacitor designed for high‑voltage, general‑purpose electronic applications. It is a radial‑lead, polarized capacitor providing 33 µF capacitance at a 400 V rated voltage in a compact φ10 × 31.5 mm can.

Engineered for long operational life and reliable performance, the UCP2G330MPD delivers 10,000 hours endurance at 105°C, controlled leakage and dissipation characteristics, and specified ripple current ratings for both low and high frequency environments.

Key Features

• Electrical Performance — 33 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) and a rated voltage of 400 V; polarized construction for DC applications.
• Ripple Handling — Rated low‑frequency ripple current 330 mA at 120 Hz and high‑frequency ripple current 495 mA at 10 kHz, allowing use in both mains‑frequency and higher‑frequency circuits.
• Leakage and Loss — Leakage current specified at 628 µA (after 1 minute at 20°C) and tangent of loss angle (tan δ) max. 0.24 at 120 Hz, 20°C for controlled dissipation.
• Long Life Endurance — 10,000 hours rated life at 105°C under DC bias plus rated ripple current; capacitance change within ±20% and leakage not exceeding initial specified value after endurance test.
• Temperature Range — Operates from −40°C to +105°C, supporting a wide range of ambient conditions.
• Compact Radial Package — φ10 × 31.5 mm can size with 5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assembly and straightforward PCB layout.
• Packaging & Availability — Supplied in bulk (no terminal forming) or bag packing; currently in mass production.

Typical Applications

• General‑Purpose Power Circuits — Energy buffering and smoothing in circuits that require a 400 V working voltage and 33 µF capacitance.
• High‑Voltage DC Link Stages — Use where long endurance at elevated temperature and controlled leakage are required.
• Industrial and Instrumentation Electronics — Through‑hole radial mounting and a −40°C to +105°C operating range suit a variety of general‑purpose designs.
