The 947C311K102CBM is designed for use in industrial applications such as electric power systems, industrial automation, and motor drive systems. It is also suitable for high-current applications, such as in switching power supplies and motor control systems. The 947C311K102CBM is designed to work in harsh environments, with temperatures ranging from -55°C to +125°C. It is also suitable for high-temperature lead-free soldering processes, up to 260°C.

The 947C311K102CBM is designed to be used in switching power supplies, with a wide range of capacitance and voltage ratings. It is also commonly used in rectifier circuits, as well as EMI and ESD protection circuits. The 947C311K102CBM can also be used in motor control and power electronics applications, due to its low equivalent series resistance (ESR) and low noise characteristics.

Working Principle

A film capacitor works by storing electric charge between two conductive plates. The plates are separated by an insulating material, such as plastic or ceramic film. When a voltage is applied across the capacitor, it stores electric charge in an electrostatic field between the two plates. The amount of charge stored is proportional to the applied voltage, and the capacitance is determined by the size and type of the insulating material between the plates.

The 947C311K102CBM uses a polyethylene terephthalate (PET) film as its dielectric material. This type of film has excellent dielectric properties and is capable of withstanding high temperatures and voltage ratings. The capacitor is also designed to have low equivalent series resistance (ESR), meaning that it can handle large currents without any issue.

The 947C311K102CBM is also designed to have a low inductance, meaning that it can respond more quickly to changes in voltage. This makes it ideal for high-speed switching applications, such as those found in motor drives and power electronics. The 947C311K102CBM also has a wide temperature range and high-temperature lead-free soldering capabilities, making it ideal for use in harsh environments.
