UCS2G330MHD

The UCS2G330MHD is a miniature, radial‑lead aluminum electrolytic capacitor in Nichicon's UCS series, optimized for high ripple current and long operating life. With a 33 µF capacitance at 400 V, it is designed for general purpose power electronics where compact size and robust ripple handling are required.

Typical use cases include power supply filtering and ballast applications; the part delivers long life at elevated temperature and is RoHS compliant.

Key Features

• Capacitance & Voltage — 33 µF rated at 400 V for bulk and high‑voltage filtering tasks.
• High Ripple Capability — Rated ripple current of 450 mA at 120 Hz and 900 mA at 100 kHz, enabling effective smoothing under AC and high‑frequency conditions.
• Long Life at Elevated Temperature — Endurance rating of 10,000 hours at +105°C (note: some UCS series sizes are rated 8,000 hours for specific dimensions).
• Wide Operating Temperature — Specified for −40°C to +105°C operation for reliable performance across common industrial environments.
• Compact Radial Can Package — Radial lead, can‑style construction with lead spacing 7.5 mm and package footprint approximately 2 × 1.6 cm, suitable for through‑hole PCB mounting.
• Polarized Electrolytic — Polarized design for DC bulk capacitance applications; capacitance tolerance ±20% at 120 Hz, 20°C.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk and output filtering where 400 V rating and high ripple current improve voltage stability and thermal endurance.
• Ballast Circuits — Suited for ballast application requirements that demand sustained ripple handling and reliability at elevated temperature.
• Industrial Power Electronics — General purpose filtering and energy storage in industrial control and power conversion equipment.

Unique Advantages

• High ripple tolerance: 900 mA at 100 kHz and 450 mA at 120 Hz provide headroom for demanding AC and high‑frequency applications.
• Extended high‑temperature life: 10,000‑hour endurance at +105°C supports longer maintenance intervals and higher reliability in hot operating environments.
• Compact footprint: Small radial can (≈2 × 1.6 cm) and 7.5 mm lead spacing enable dense through‑hole layouts without sacrificing performance.
• Wide operating range: −40°C to +105°C rating accommodates a broad set of industrial and commercial deployments.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for assembled products.
