Aluminum electrolytic capacitors are passive components that are commonly used in many electronic devices to store energy. They are widely used in applications such as power supply circuit stabilization, frequency modulation, and energy storage. The LNT2V682MSEHBB is a type of aluminum electrolytic capacitor with a specific set of application fields and working principles.

Application Field

The LNT2V682MSEHBB datasheet states that the device is an aluminum electrolytic capacitor with a rated capacitance of 6.8uF and rated voltage of 16V. It is characterized by its leak-proof non-polarized construction, low impedance, and good long-term reliability.

This type of aluminum electrolytic capacitor is appropriate for use in general general electronic circuits, such as switching power supplies, computers, and white goods. It is also useful for storing energy in circuits with high transient loads, such as camera shutters, reed relays, and microcontroller-driven switching systems.

Furthermore, the LNT2V682MSEHBB capacitors have a broad temperature range of -40 to +105°C. This makes them suitable for use in more extreme environments, such as in automotive applications or outdoor equipment.

Working Principle

An aluminum electrolytic capacitor works by using two aluminum foil electrodes, separated by paper impregnated with an organic liquid electrolyte. This creates a sandwich-like arrangement that is sealed in a metal container with sealing and safety valves. The two aluminum electrodes between the cooling fins prevent the electrolyte from leaking out after being over charged.

When a voltage is applied to the capacitor, the positive charge is attracted to the negative aluminum electrode, forcing the ionic charges of the electrolyte to rearrange and to create an electrical double layer at the aluminum foil electrodes. This double layer creates the capacitance effect and stores charge until it is discharged again.

The LNT2V682MSEHBB has a capacitor winder to maintain the temperature-independent capacitance. This device features an electrolyte of glycol and a flexible graphite gasket, creating a low ESR, an important component of stability in high-frequency circuits. Furthermore, the low impedance of the capacitor and its leak-proof construction ensures a longer lifetime and excellent vibration resistance, making it suitable for long-term reliable applications.

To summarize, the LNT2V682MSEHBB aluminum electrolytic capacitor is a device designed for applications requiring improved temperature stability, low impedance, and extended operational lifetime. Its wide temperature range and leak-proof construction make it suitable for automotive and outdoor equipment. Furthermore, the low ESR of this capacitor, combined with its flexible graphite gasket, makes it a reliable choice for long-term use in high-frequency circuits.
