LAQ2G820MELZ30

The LAQ2G820MELZ30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LAQ series, specified at 82 µF with a 400 V rated voltage and ±20% capacitance tolerance. It is built for general‑purpose power applications that require high DC voltage handling, defined ripple performance, and extended endurance at elevated temperatures.

Designed for tray packing and mass production, this smaller‑sized snap‑in can offers a compact footprint (φ22 × 30 mm) and is specified for operation from −25 °C to +105 °C with an endurance rating of 2000 hours at 105 °C.

Key Features

• Capacitance & Tolerance — 82 µF with ±20% tolerance at 120 Hz, 20 °C, providing predictable capacitance for power‑supply filtering and smoothing.
• High Voltage Rating — 400 V rated voltage suitable for high‑voltage DC circuits within the LAQ series voltage options.
• Ripple Current Performance — 580 mA at 120 Hz (low frequency) and 667 mA at 10 kHz (high frequency), enabling reliable performance under AC ripple loading.
• Low Leakage — Specified leakage current of 540 µA after rated voltage application, supporting stable DC performance.
• Temperature & Endurance — Operating range −25 °C to +105 °C with 2000 hours endurance at 105 °C when tested under rated conditions.
• Package & Mounting — Snap‑in radial can (φ22 × 30 mm) for secure board mounting and compact power‑module integration; supplied in tray packing for production assembly.
• Safety Design — Series safety performance includes a pressure relief vent designed to operate under abnormal conditions without creating flames or dispersion of parts.

Typical Applications

• General‑purpose power filtering — Provides bulk energy storage and ripple smoothing in power supplies and DC bus circuits where 400 V rating and defined ripple current capability are required.
• Industrial power electronics — Used in assemblies that operate up to +105 °C and require robust, snap‑in mounted electrolytic capacitance for reliable operation under thermal stress.
• Energy storage and decoupling — Suited for decoupling and energy buffering in high‑voltage power modules where low leakage and stable capacitance are important.

Unique Advantages

• High‑voltage readiness: 400 V rating enables deployment in higher‑voltage DC circuits without the need for series stacking.
• Temperature endurance: 2000‑hour rating at 105 °C supports designs that experience sustained elevated temperatures, helping ensure long‑term performance.
• Defined ripple capability: Separate ripple current specifications at low and high frequency (580 mA @120 Hz, 667 mA @10 kHz) allow designers to match capacitor selection to expected ripple profiles.
• Compact snap‑in package: φ22 × 30 mm radial can with snap‑in terminals offers a space‑efficient, board‑secure mounting solution for mass production.
• Predictable leakage behavior: Specified leakage current of 540 µA provides a clear parameter for power‑budget and standby‑leakage calculations.
• Series safety measures: Pressure relief venting is specified to operate without flame or dispersion, addressing safety considerations in system design.
