UPJ1V331MHD6

The UPJ1V331MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, can-type capacitor specified at 330 µF and 35 V, designed for general-purpose use and particularly suited to switching power supply applications where low impedance is required.

Key electrical characteristics include a loss tangent (tanδ) of 0.12 measured at 20°C and 120 Hz, low- and high-frequency ripple current capability, a rated operating temperature range from −55°C to 105°C, and a 5000-hour endurance at 105°C. The unit is RoHS compliant and available in bulk or bag packing.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with tolerance −20% ~ +20% rated at 35 V, providing stable bulk energy storage for power circuits.
• Low Loss / Low Impedance — tanδ (DF) 0.12 measured at 20°C, 120 Hz, supporting efficient performance in filtering and smoothing applications.
• Ripple Current Handling — Low-frequency ripple current 452.4 mA (120 Hz) and high-frequency ripple current 780 mA (200 kHz), enabling effective handling of both line and switching noise components.
• Leakage Current — Specified leakage current of 346.5 µA after rated voltage application, suitable for general-purpose power designs.
• High Reliability Endurance — Rated for 5000 hours at 105°C, providing extended service life in elevated-temperature environments.
• Compact Radial Package — Can-style body φ12.5 × 15 mm (diameter × length) with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and tailored ripple current capability make this capacitor well-suited for input/output filtering and smoothing in switching regulators.
• General-Purpose Power Filtering — Bulk decoupling and smoothing in consumer and industrial electronic equipment operating across −55°C to 105°C.
• Through-Hole Assemblies & Prototyping — Radial lead package with 5 mm lead spacing supports straightforward PCB assembly and replacement in repair or prototyping workflows.
• Elevated-Temperature Systems — Designed for long-term operation at elevated temperatures with a 5000-hour endurance rating at 105°C.

Unique Advantages

• Designed for Switching Environments: Low impedance and specific ripple current ratings support effective filtering in switching power supplies.
• Long Endurance at High Temperature: 5000-hour rating at 105°C supports extended reliability in thermally demanding applications.
