LAQ2D681MELB30ZB

The LAQ2D681MELB30ZB from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LAQ series, designed for general‑purpose use where compact size, high voltage capability and elevated temperature endurance are required. It is a polarized, radial can (snap‑in) capacitor rated at 200 V with a nominal capacitance of 680 µF.

Designed for applications exposed to fluctuating voltages, this smaller‑sized LAQ series part offers extended ripple capability and enhanced safety features, alongside long‑life endurance at high operating temperature (–25°C to +105°C).

Key Features

• Rated Capacitance and Voltage — 680 µF nominal capacitance at a rated voltage of 200 V, with capacitance tolerance of ±20% (–20%~20%).
• Snap‑in Radial Can Package — Snap‑in terminal mounting in a compact radial can form factor; nominal size L: 3 × D: 3 cm for space‑constrained boards.
• High Temperature Endurance — Specified operating temperature range of –25°C to +105°C with rated endurance: 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current performance of 1.75 A at 120 Hz and 2.1 A at 10 kHz for effective smoothing and energy handling in power circuits.
• Stability and Lifetime — Endurance requirement: capacitance change within ±20% after the 2000‑hour test at 105°C; shelf life requirement: capacitance change within ±15% after 1000 hours at 105°C plus voltage treatment.
• Improved Safety for Abnormal Voltage — LAQ series includes enhanced safety features for abnormally excessive voltage and a pressure relief vent designed to operate without creating dangerous conditions.
• Polarized Device — Polarized construction suitable for DC applications where polarity is maintained.

Typical Applications

• Power supply filtering and smoothing — Use the 680 µF capacitance, 200 V rating and specified ripple current values to handle ripple and stabilize DC rails.
• Industrial equipment exposed to voltage fluctuation — The LAQ series’ enhanced safety features and permissible abnormal voltage characteristics suit equipment operating in environments with fluctuating supply voltages.
• General‑purpose bulk energy storage — Compact snap‑in packaging and long‑life high‑temperature endurance support general‑purpose bulk decoupling and buffering in rack and cabinet systems.

Unique Advantages

• High‑temperature reliability: Rated for continuous operation at up to 105°C with a specified 2000‑hour endurance test for sustained performance in hot environments.
• Measured ripple performance: Explicit ripple current specifications at both 120 Hz and 10 kHz provide predictable thermal and filtering behavior for designers.
• Compact snap‑in form factor: Smaller case size in the LAQ series gives a balance of capacitance and board‑level volume for tighter layouts.
• Safety‑oriented design: Pressure relief vent and series‑level safety testing for abnormal voltage reduce risk under fault conditions.
• Proven stability: Defined limits for capacitance change, tan δ and leakage after endurance and shelf‑life tests provide measurable long‑term characteristics.
