LAQ2G680MELZ25ZB

The LAQ2G680MELZ25ZB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LAQ series, offering 68 µF capacitance at a 400 V rated voltage in a compact radial can package (φ22 × 25 mm). It is a polarized, general-purpose capacitor designed for applications requiring high-voltage handling, measured ripple capability, and robust high-temperature endurance.

Its combination of a snap-in mounting style, measured ripple current at both low and high frequencies, and a 2000‑hour endurance rating at 105°C makes it well suited for equipment exposed to voltage fluctuation and for power circuits where compact, reliable bulk capacitance is required.

Key Features

• Core Type: Aluminum electrolytic, snap-in terminal — polarized design for bulk capacitance in power circuits.
• Voltage & Capacitance: 68 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance for reliable energy storage at higher DC voltages.
• Ripple Current Performance: Specified ripple handling of 510 mA at 120 Hz and 586.5 mA at 10 kHz to support AC ripple and switching noise in power systems.
• Temperature & Endurance: Operates from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under rated ripple and D.C. bias.
• Package & Mounting: Radial can, snap-in package sized φ22 × 25 mm (L: 2.5 × D: 2.2 cm) for secure chassis or PCB-mounted bulk capacitance.
• Leakage Current: Measured leakage current of 490 µA, suitable for power applications where low standby leakage is required.
• Safety & Reliability: Designed with improved safety features for abnormal voltage conditions and a pressure relief vent to reduce risk under fault conditions.
• Regulatory: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the LAQ series documentation.

Typical Applications

• Power supply filtering: Bulk smoothing and decoupling in high-voltage DC power supplies where 400 V rating and measured ripple current are required.
• Equipment subject to voltage fluctuation: Systems operating in variable-line environments that benefit from the LAQ series’ improved safety features for abnormal voltage conditions.
• Industrial control and power conversion: Support for DC link, smoothing, and energy storage in industrial controllers and converters that need compact, high-voltage capacitors.
• General-purpose electronic equipment: Applications requiring robust, snap-in mounted electrolytic capacitance for long-term operation at elevated temperatures.

Unique Advantages

• High-voltage capability: 400 V rating provides margin for high-voltage DC applications and supports extended voltage system designs.
• Measured ripple specs at dual frequencies: Explicit ripple current ratings at 120 Hz and 10 kHz (510 mA and 586.5 mA) give predictable thermal and performance behavior across common power frequencies.
• Compact, secure snap-in package: φ22 × 25 mm radial can with snap-in terminals offers space-efficient mounting and mechanical stability for chassis or PCB installations.
• High-temperature endurance: 2000 hours at 105°C ensures durability for sustained high-temperature operation and extended field life under rated conditions.
• Safety-focused design: Improved safety measures for abnormally excessive voltage and a pressure relief vent reduce risk under fault scenarios.
• RoHS compliance: Series-level compliance with RoHS directives supports environmental and regulatory requirements.
