UVZ2F331MRD

The UVZ2F331MRD is a polarized aluminum electrolytic capacitor in a radial lead can, featuring 330 µF capacitance at a 315 V rating. Designed for general-purpose through-hole applications, it delivers high-voltage capability with a compact φ25 × 50 mm can size and 12.5 mm lead spacing.

Key value comes from its wide operating temperature range (−40°C to +105°C), specified ripple performance at both low and high frequencies, and a 2000 hour endurance rating at 105°C—addressing applications that require stable bulk capacitance and sustained operation under elevated temperature.

Key Features

• Capacitance & Tolerance — 330 µF with ±20% tolerance (120 Hz, 20°C), providing specified bulk energy storage for decoupling and smoothing.
• High Voltage Rating — 315 V rated voltage for high-voltage DC bus and power supply designs.
• Ripple Current Performance — Low-frequency ripple current 760 mA (120 Hz) and high-frequency ripple current 874 mA (10 kHz), enabling reliable ripple handling across a range of switching and line frequencies.
• Leakage Current — Specified leakage current of 4258 µA for this part, useful for design-level leakage budgeting.
• Temperature & Endurance — Operating temperature −40°C to +105°C with a rated life of 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Package & Mounting — Radial lead, polarized can (φ25 × 50 mm) with 12.5 mm lead spacing (±0.5 mm), suited for through-hole PCB mounting and hand or machine assembly.
• Regulatory Compliance — RoHS compliant as indicated in the product data.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible inventory and assembly workflows.

Typical Applications

• General Purpose Power Electronics — Use where a polarized aluminum electrolytic capacitor is required for bulk energy storage and smoothing in through-hole designs that need 315 V capability.
• High-Voltage DC Bus — Suitable for DC bus and mid-voltage sections in power supplies and converters that require 330 µF at 315 V and defined ripple handling.
• Industrial and Commercial Equipment — Suited to equipment operating across −40°C to +105°C and requiring capacitors with 2000 hour endurance at elevated temperature.

Unique Advantages

• High-Voltage Capability: 315 V rating enables use in higher-voltage power rails without additional series components.
• Broad Temperature Endurance: Rated for −40°C to +105°C and 2000 hours at 105°C, helping maintain capacitance and loss characteristics under thermal stress.
• Measured Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz give clear design parameters for both low-frequency line ripple and high-frequency switching environments.
• Compact Through-Hole Form Factor: φ25 × 50 mm radial can with 12.5 mm lead spacing supports straightforward through-hole integration and mechanical stability on the PCB.
• RoHS Compliance and Packaging Flexibility: RoHS compliance and availability in bulk or bag packing simplify procurement and assembly planning.
