URZ2A331MHD

The URZ2A331MHD is an aluminum electrolytic capacitor in a radial-lead can from Nichicon’s URZ series. It provides 330 μF capacitance at a 100 V rating in a compact, low-profile radial package designed for general-purpose electronic applications.

This part offers a wide operating temperature range and defined endurance characteristics, making it suitable for designs that require stable capacitance, controlled loss (tan δ), and specified ripple handling over long-term operation.

Key Features

• Capacitance & Voltage — 330 μF nominal capacitance with a 100 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Loss (tan δ) — Tangent of loss angle specified as 0.08 (measured at 20°C, 120 Hz), supporting effective energy storage with controlled dissipation.
• Ripple Current Capability — Rated low-frequency ripple current of 540 mA at 120 Hz and a high-frequency ripple current of 810 mA at 10 kHz, with frequency coefficients defined by the URZ series.
• Leakage Current — Specified leakage current of 990 μA (per product data), providing predictable standby behavior after voltage application.
• Wide Temperature Range & Endurance — Operates from −55°C to +105°C with an endurance rating of 1000 hours at 105°C under rated voltage.
• Package & Mounting — Radial lead (can) construction with 7.5 mm lead spacing and available in bulk or bag packing for production handling.

Typical Applications

• General-purpose electronic circuits — For designs requiring 330 μF at 100 V where a radial-lead electrolytic capacitor is appropriate.
• Power filtering and bulk energy storage — Use where defined ripple current handling (540 mA @120 Hz, 810 mA @10 kHz) and stable capacitance over temperature are required.
• Industrial and commercial equipment — Suitable for equipment operating across a wide ambient range (−55°C to +105°C) with long-duration thermal endurance needs.

Unique Advantages

• High voltage capability: 100 V rating allows use in higher-voltage circuits without series stacking.
• Predictable loss behavior: Low tan δ (0.08 at 20°C/120 Hz) supports designs sensitive to dissipation and heating.
• Defined ripple performance: Specified ripple currents at both low and high frequencies help engineers size components for thermal and lifetime targets.
• Wide temperature tolerance and endurance: −55°C to +105°C range and 1000 h endurance at 105°C provide design margin for demanding environments.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production, easing procurement for volume builds.
