Working Principle

The 930C4W1K-F is a di-electric capacitor consisting of two metallic electrodes separated by a thin layer of dielectric material, typically paper and plastic polymeric film. In its simplest form, a capacitive device is simply two metal plates separated by a layer of an insulator that can hold an electrostatic charge when a voltage is applied across the electrodes. When connected in a circuit, the capacitor will hold an electrostatic charge proportional to the amount of charge that is flowing through it.

When AC voltage is applied to the 930C4W1K-F, the AC voltage is stored in the capacitor’s dielectric layer and is then discharged when the voltage across the device is reduced or reaches zero. This cycle repeats in a continuous fashion until the AC power is removed from the capacitor or until the capacitors self-discharge. The capacitance of the 930C4W1K-F can be altered by changing the thickness of the dielectric layer, thus allowing the engineers to tailor the device’s performance to meet their specific design requirements.

The 930C4W1K-F is designed to provide an extremely low level of self-inductance, effectively eliminating the safety concerns associated with other capacitors in the same class. Its high temperature stability allows the device to function in extreme temperature environments without sacrificing the performance of the device.
