UVP1A331MPD

The UVP1A331MPD is a bi-polar aluminum electrolytic capacitor from Nichicon’s UVP series, designed for standard bi-polarized applications in entertainment electronics and general-purpose consumer equipment. It provides a 330 µF capacitance at a 10 V rating in a compact radial-can package with radial leads.

Engineered for reliability across a wide temperature range, this capacitor offers defined ripple current handling at both low and high frequencies, RoHS compliance, and a 2,000-hour endurance rating at 85°C with polarity inversion testing per the series specification.

Key Features

• Bi-Polar Construction Suitable for circuits that require non-polarized capacitor behavior; part of a standard bi-polarized series for entertainment electronics.
• Electrical Characteristics 330 µF capacitance at 10 V rated voltage with capacitance tolerance ±20% (−20% to +20%).
• Ripple Current Performance Rated ripple current of 345 mA at 120 Hz and 517.5 mA at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Frequency Behavior Frequency coefficient data for the UVP series applies (for 100–470 µF: 1.00 at 120 Hz and 1.50 at 10 kHz), allowing designers to scale ripple ratings by frequency.
• Reliability & Endurance Endurance tested to 2,000 hours at 85°C with polarity inverted every 250 hours; leakage current spec per series (after 5 minutes at 20°C, not more than 0.03CV µA).
• Mechanical / Packaging Radial lead, radial-can package with 5 mm lead spacing and compact dimensions (L: 1.6 × D: 1.0 cm), designed for through-hole mounting.
• Operating Range & Compliance Rated for −40°C to +85°C operating temperature and RoHS compliant (2011/65/EU,(EU)2015/863).
• Loss Characteristics Series tan δ specification at 10 V: 0.24 (measurement at 120 Hz, 20°C), providing a reference for dissipation factor in circuit design.

Typical Applications

• Entertainment Electronics Designed for standard bi-polarized roles in consumer entertainment systems where non-polarized capacitors are required.
• General-Purpose Consumer Equipment Useful in a variety of general-purpose circuits within consumer devices that require radial through-hole mounting and compact capacitor sizing.
