UPJ2G330MHD

The UPJ2G330MHD is a radial-lead, miniature aluminum electrolytic capacitor in Nichicon’s UPJ series designed for high-reliability power applications. It delivers low impedance and endurance for power filtering where sustained performance at elevated temperature is required.

Configured as a polarized, through-hole component, this part is targeted at general-purpose power designs and is specifically well suited for switching power supplies that require robust ripple handling and long life at high operating temperatures.

Key Features

• Electrical Characteristics — 33 µF capacitance with ±20% tolerance and a rated voltage of 400 V, suitable for high-voltage DC filtering.
• Low Loss / Dissipation — Dissipation factor (tanδ) of 0.25 measured at 20°C, 120 Hz, supporting stable filtering performance.
• Ripple Performance — Low-frequency ripple current 170 mA (120 Hz) and high-frequency ripple current 272 mA (200 kHz) for effective smoothing in switching supplies.
• Leakage and Polarization — Polarized capacitor with specified leakage current of 628 µA, measured under rated conditions.
• High Reliability Endurance — Rated for 5000 hours life at 105°C, enabling prolonged operation under elevated temperature stress.
• Mechanical and Mounting — Radial lead mounting with 7.5 mm lead spacing (±0.5 mm) and compact can size φ18 × 35.5 mm length for through-hole PCB implementations.
• Environmental Compliance — RoHS compliant.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit production or prototyping workflows.

Typical Applications

• Switching Power Supplies — Provides output and input filtering with ripple current capability and long-term thermal endurance.
• General Purpose Power Filtering — Suited for DC bus decoupling and bulk storage in industrial and electronic power designs.
• Through-Hole PCB Designs — Radial lead form factor and compact φ18×35.5 mm size make it easy to integrate into through-hole assemblies.

Unique Advantages
