125LC5112K5PM8

Film capacitors, also known as polyester capacitors, are widely used in electronic circuits due to their superior properties and wide range of applications. The 125LC5112K5PM8 is a type of film capacitor designed for use in high-power and high-voltage applications. It is a self-healing, polarized capacitance element that is capable of handling currents up to 5A and has a breakdown voltage of up to 8800V AC and 1750V DC. It is designed to operate in a wide range of temperatures, from -40C to +85C.

The 125LC5112K5PM8 is constructed using polypropylene film, metalized aluminum electrodes, and a polyethylene (PE) cover. The metalized aluminum electrodes are used for electrical connection and also to increase the inductance of the capacitor. The PE cover provides both electrical and mechanical protection. The capacitor is also designed to be self-healing, which means that it can repair itself after breakage or puncture due to mechanical or electrical stress.

The primary application field of the 125LC5112K5PM8 is in power supply filters. This type of capacitor is especially useful in applications where a large amount of energy is expected to be transferred from one circuit to another, such as from a power supply to its load. It is also used in phase-shift networks, coupling circuits, and voltage boosters. Additionally, it is suitable for a number of other high-power electronic applications.

The working principle of the 125LC5112K5PM8 is based on the properties of the film materials it is constructed from. The combination of polypropylene film and metalized aluminum electrodes allows for the capacitor to capacitate a high amount of energy in a small package. The metalized aluminum electrodes act as the two power lines of the capacitor and provide an inductive pathway for the energy to pass through. The capacitor is then able to store the energy until it is needed by the circuit.

The 125LC5112K5PM8 is a great choice for applications requiring high power and high voltage. Its self-healing properties make it reliable and durable, while its high performance capabilities allow it to be used in a wide range of applications. Its high capacitance and low profile make it a great choice for power supply filters, phase-shift networks, coupling circuits, and voltage boosters.
