Film capacitors are one of the most commonly used electrical components in a variety of industry and consumer electronics such as televisions, computers, and sound systems. The B81130C1105M is a particular type of film capacitor that has two primary characteristics that set it apart from other types of capacitors. These characteristics are its application field and working principle.

Application Field

The B81130C1105M is a polyester film capacitor specifically designed for applications in high voltage and high pulse current power supplies, inverters, and general purpose DC/DC converters. It is an ideal choice for high-speed switching applications, due to its high dielectric strength, low ESR (equivalent series resistance), and high ripple current capability. The B81130C1105M can also be used in thyristor-controlled power supplies, power line conditioning circuits, and lighting systems.

This capacitor is rated for an operating temperature range of - 40°C to + 110°C. It has a rated voltage of 500VAC and a capacitance of 0.1μF, making it suitable for use in high frequency and ripple current applications. The B81130C1105M is capable of withstanding pulses of up to 1000V, meaning it can be used even in particularly demanding environments.

Working Principle

The B81130C1105M is a polyester film capacitor that works by storing energy in the form of an electrical field. This energy is then released as a capacitor discharges. This capacitor is made up of two metallic plates that are separated by an insulating dielectric material. As a voltage is applied to the capacitor, electrons accumulate on one plate, creating an electrostatic field between the two plates. The stored energy is then released as the capacitor discharges or reverses its polarity.

This capacitor has a low ESR, resulting in low power loss and high ripple current capability. It is also able to withstand high pulse currents, making it suitable for use in high speed switching applications. The B81130C1105M also has a high dielectric strength, making it able to withstand high voltage pulses.

Capacitors are a critical component in a wide range of electrical and electronic systems. The B81130C1105M is a particularly impressive example of this critical component, because of its ability to withstand high voltage and high pulse currents. This makes it an ideal choice for high speed switches and power line conditioning circuits.
