LAQ2G820MELA25ZB

The LAQ2G820MELA25ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, featuring an 82 µF capacitance with ±20% tolerance and a 400 V rated voltage. Its snap‑in radial can package and compact φ25 × 25 mm dimensions are designed for robust, general‑purpose power applications.

This part is specified for -25°C to 105°C operation with an endurance rating of 2000 hours at 105°C. Key electrical characteristics include low leakage current (0.54 mA) and defined ripple current capability (580 mA at 120 Hz, 667 mA at 10 kHz), making it suitable for high‑voltage power filtering and energy‑storage roles in production designs.

Key Features

• Electrical Performance — 82 µF capacitance at 400 V with ±20% tolerance provides stable bulk capacitance for high‑voltage circuits.
• Ripple Handling — Rated ripple current of 580 mA at 120 Hz and 667 mA at 10 kHz supports smoothing of AC‑derived ripple and switching noise in power supplies.
• Low Leakage — Specified leakage current of 0.54 mA for minimized standby losses and predictable DC behavior after application of rated voltage.
• Thermal and Lifetime Specified — Operating range of -25°C to 105°C and 2000 hours endurance at 105°C when subjected to rated DC bias plus rated ripple current.
• Snap‑In Radial Can Package — Snap‑in terminals in a φ25 × 25 mm can for secure board mounting and mechanical stability in production assemblies.
• Series Safety Features — Series specification includes a pressure relief vent designed to operate under abnormal conditions to avoid dangerous failure modes.
• Production Ready — Tray packing and mass production status support volume procurement and manufacturing workflows.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple attenuation on high‑voltage rails in AC/DC and DC/DC supplies.
• Converter and Inverter Energy Storage — Local energy reservoir for stabilizing voltage during switching events and load transients.
• Industrial Power Electronics — Decoupling and filtering in industrial power modules that require 400 V rated bulk capacitance.
• General‑Purpose High‑Voltage Circuits — Use wherever a 400 V polarized aluminum electrolytic with defined ripple and lifetime specs is required.

Unique Advantages

• 400 V Rated Voltage: Enables direct use on high‑voltage rails without series stacking, simplifying design.
• Defined Ripple Ratings: Separate low‑ and high‑frequency ripple specifications (580 mA @120 Hz, 667 mA @10 kHz) allow designers to size thermal and lifetime budgets accurately.
• Endurance at Elevated Temperature: 2000 hours at 105°C with specified post‑test limits provides predictable lifetime behavior in warm environments.
• Compact Snap‑In Form Factor: φ25 × 25 mm can with snap‑in terminals reduces board footprint while delivering high‑voltage capacitance.
• Low Leakage Current: 0.54 mA leakage supports applications where minimal DC loss and predictable insulation performance matter.
• Production‑Oriented Packaging: Tray packing and mass production readiness streamline procurement and assembly for volume programs.
