Film Capacitors

Film capacitors, also known as film dielectric capacitors, are small, cost-effective, low loss, general purpose capacitors that can be optimized for special applications by changing the dielectric material. They are widely used as coupling, decoupling, and bypass capacitors in communications, power electronics, and other related circuits.The 124MKP275KD is a high performance film capacitor that offers superior capacitor reliability, quality and performance over other capacitors. It uses an innovative method of construction with an ultra-thin dielectric that has extremely high breakdown voltage, along with a geometric design that lowers overall inductance and better handling of high frequency emission. The capacitor also features a very low ESR for excellent heat dissipation, making it the ideal choice for both power electronics and high frequency communications.

Application Field

The 124MKP275KD film capacitor has a wide range of applications, ranging from high-tech medical equipment to consumer electronics. Its ability to operate reliably in harsh environmental conditions due to its dielectric material make it especially popular in industrial applications as well, such as high-voltage motors, power conversion systems, and power conditioners. Additionally, it can be used for motor drives, switch mode power supply circuits, and for general purpose power electronics.

Working Principle

The working principle of the 124MKP275KD film capacitor is based on the principle of the capacitance-voltage relationship, which states that the capacitance of a capacitor is proportional to the inverse of the voltage applied to it. When a capacitor is charged and then discharged, the capacitance of its dielectric material is changed, resulting in a change in the capacitor’s charge and its reactive power.As the voltage increases, the dielectric material’s permittivity increases and the capacitance decreases. Conversely, as the voltage decreases, the dielectric material’s permittivity decreases and the capacitance increases. This means that the effective capacitance of the capacitor can be changed by changing the applied voltage.The 124MKP275KD film capacitor also has a higher breakdown voltage than traditional capacitors, meaning that the device can operate more reliably against higher voltages and frequencies. Additionally, due to its low temperature coefficient and low ESR, it provides more efficient operation and longer life.Because of its high breakdown voltage and low internal losses, the 124MKP275KD is an ideal solution for a variety of situations, from consumer electronics to high power transmission cables. The capacitor’s very low internal resistance also makes it a great choice for power electronics applications and for high frequency communications.
