UPJ2W330MHD

The UPJ2W330MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series designed for through-hole, radial-lead applications. It delivers 33 µF capacitance at a 450 V rated voltage and is specified for general-purpose and power supply use where compact high-voltage bulk capacitance and defined ripple performance are required.

Key attributes include a long endurance rating at elevated temperature, defined low- and high-frequency ripple current ratings, and a compact radial-can package (φ18 × 40 mm) with 7.5 mm lead spacing for straightforward PCB integration.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with ±20% tolerance and a 450 V rated voltage for high-voltage DC rail support.
• Electrical Loss — Specified dissipation factor (tanδ) of 0.25 measured at 20°C, 120 Hz, enabling predictable AC loss and heating behavior in design calculations.
• Ripple Performance — Low-frequency ripple current 170 mA (120 Hz) and high-frequency ripple current 272 mA (200 kHz), giving defined performance at both mains-frequency and switching frequencies.
• Leakage Current — Leakage current specified at 694 µA, useful for bias and standby current budgeting.
• High-Temperature Endurance — Rated for 5000 hours life at 105°C, supporting designs that require sustained operation at elevated ambient temperatures.
• Operating Range & Polarization — Polarized aluminum electrolytic rated for operation from -25°C to +105°C.
• Package & Mechanical — Radial leaded can, size φ18 × 40 L (4.0 × 1.8 cm), 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk and smoothing capacitor on high-voltage DC rails, with ripple specifications for both low- and high-frequency components.
• Industrial Power Electronics — DC-link and energy-storage decoupling in high-voltage power conversion modules operating up to 105°C.
• General-Purpose High-Voltage Circuits — Through-hole designs that require compact, polarized aluminum electrolytic capacitance rated to 450 V.

Unique Advantages

• High Voltage Capability: 450 V rating enables direct use on elevated DC rails without series configurations.
• Defined Ripple Data: Published LF and HF ripple current values help ensure reliable thermal and lifetime margining in both mains-frequency and switching-frequency designs.
• Long Endurance at Elevated Temperature: 5000 hours at 105°C provides clearly specified lifetime expectation for high-temperature applications.
• Compact Radial Package: φ18 × 40 mm can with 7.5 mm lead spacing supports easy through-hole PCB placement and mechanical robustness.
• Predictable Dissipation: Specified tanδ (0.25 at 20°C, 120 Hz) yields quantifiable loss estimates for thermal and ESR-based calculations.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance in manufacturing.
