LAK2G680MELZ25

The LAK2G680MELZ25 from Nichicon is a snap-in terminal aluminum electrolytic capacitor rated for 400 V with 68 µF capacitance and ±20% tolerance. It is part of the LAK series designed for robust high-voltage use, offering long endurance and safety features for equipment exposed to voltage fluctuations.

Key attributes include a 2000 h endurance at 105 °C, a wide operating temperature range of −25 °C to 105 °C, and snap-in radial mounting in a compact φ22 × 25 mm can — suited to general-purpose electronic equipment requiring high-voltage energy storage and ripple handling.

Key Features

• Rated Performance: 68 µF capacitance at 400 V DC with ±20% tolerance, providing energy storage for high-voltage circuits.
• High temperature endurance: Specified for 2000 hours at 105 °C when subjected to DC bias plus rated ripple current, supporting extended operation in elevated-temperature environments.
• Ripple current handling: 400 mA at 120 Hz (low frequency) and 460 mA at 10 kHz (high frequency), enabling effective smoothing under varying ripple conditions.
• Leakage and dissipation: Low leakage current specified at 490 µA and tan δ (DF) of 0.20 max at 20 °C, 120 Hz for predictable loss performance.
• Snap-in radial package: φ22 × 25 mm can with snap-in terminals for secure PCB mounting and mechanical retention in power assemblies.
• Safety and voltage tolerance: Designed with improved safety features for abnormally excessive voltage and a pressure-relief vent that operates without dangerous conditions, per the LAK series specification.
• Wide ambient range: Operating temperature from −25 °C to 105 °C for use across varied environmental conditions.
• RoHS compliant: Conforms to RoHS requirements for restricted substances.

Typical Applications

• General-purpose high-voltage equipment: Used where 400 V energy storage and smoothing are required in general-purpose electronic systems.
• Power supplies and converters: Employed for ripple filtering and bulk energy storage in supplies that must tolerate fluctuating voltages and elevated temperatures.
• Industrial electronic assemblies: Snap-in mounting and the φ22 × 25 mm package provide a compact, mechanically robust capacitor option for industrial power modules.

Unique Advantages

• Long-term high-temperature reliability: 2000-hour endurance at 105 °C ensures stable capacitance and controlled dissipation after extended operation at elevated temperatures.
• High-voltage capability: 400 V rating accommodates demanding power circuits and applications that require extended voltage range within the LAK series.
• Effective ripple performance: Specified ripple currents at both 120 Hz and 10 kHz give designers clear margins for low- and high-frequency ripple handling.
• Safety-focused design: Series-level safety measures, including a pressure-relief vent, reduce risk under abnormal over-voltage conditions.
• Compact, secure mounting: Snap-in radial can enables straightforward PCB installation and mechanical stability in power assemblies.
• Regulatory compliance: RoHS compliance supports use in markets with restricted-substance requirements.
