Film Capacitors

Film capacitors are used as voltage-dividing capacitors, internal signal coupling capacitors, power supply-line bypass capacitors, interference suppressing capacitors, and more. They are generally polarised and have a high insulation resistance, a low dissipation factor and high stability. The MKT1813610016M is one such film capacitor and here we will provide an overview of its application fields and working principle.

Application Fields of MKT1813610016M

The MKT1813610016M is a bi-polar film capacitor designed for use in low-voltage power electronics. It is suitable for smoothing out voltage spikes and increasing the capacity of circuits, and is ideal for communication devices, data storage devices, and small appliances. The product is capable of withstanding voltages of up to 500V AC and is designed for use in medical and audio equipment.

The product has a maximum capacitance of 120nF and a minimum breakdown voltage of 2.5kV. It is rated for a surge current of up to 1.3mA and a dielectric dissipation factor of less than 0.004. The product has a maximum working temperature of 105 degrees Celsius and is compatible with lead-free soldering processes.

The product also has some protection features, such as self-healing and MOV (Metal Oxide Varister) protection to help reduce damage and wear. It is also UL and CE certified for safety and reliability.

Working Principle of MKT1813610016M

The MKT1813610016M is a film capacitor, which means it consists of two metal plates separated by a dielectric film (typically thin plastic or paper). When a voltage is applied to the capacitor, a static electric field is formed between the two metal plates, which in turn creates an electrical charge. This electrical charge creates a reacting electrical field between the two plates, also known as electrostatic force.

The electrical field formed by the two plates and the electrostatic force results in the formation of an electrical current, known as a capacitive current. This current is sustained until the voltage applied is removed. The capacitance (measure of how much charge a capacitor can store) is dependent on the area of the capacitor plates, the thickness of the dielectric, and the material of the dielectric.

The MKT1813610016M has self-healing and MOV protection features, which are designed to reduce the impact of short-circuit current or transient spikes. The MOV protection feature works by redirecting current away from the capacitor and to the MOV, which dissipates the current and helps prevent the capacitor from becoming irreparably damaged.

Conclusion

The MKT1813610016M is a film capacitor designed for use in low-voltage power electronics applications. Its features make it ideal for many applications, including audio and medical equipment, communication devices, and data storage devices. Its working principle is based on electrostatic forces and capacitive current, with self-healing and MOV protection features helping to protect the capacitor from damage.
