935C4W2K-F

Film Capacitors

Film capacitors are a type of capacitor that uses thin plastic films to store electrical charges. They are most commonly used in electronic circuit applications where high dielectric strength, low leakage and low dissipation factor are required.

The 935C4W2K-F is a film capacitor designed for use in a wide variety of applications, from medical equipment and power supplies to automotive, telecom and military applications. It is designed to meet both EMI/RFI suppression and power smoothing/filtering requirements. It is rated at 4W, 2KV and is offered in two common case sizes: 21.8mm and 31.8mm.

Application Field and Working Principle

The 935C4W2K-F is primarily used in EMI/RFI suppression and power smoothing/filtering applications. It can be used in high-current applications, or in low-current applications that demand very low EMI/RFI signature. It is also suitable for use in applications requiring a higher peak power rating.

The 935C4W2K-F is designed to operate on alternating currents with symmetrical peak voltages up to the rated value. It works by using its layer of plastic film to store an electrical charge. This plastic film is treated with a temperature- controlled wax to build a strong dielectric barrier. This wax also lubricates the layers of plastic film and helps to increase insulation resistance.

The 935C4W2K-F provides very high capacitance stability and reverse leakage protection. The high stability allows the capacitor to withstand high in-rush currents without experiencing excessive losses of capacitance over time. It also provides good thermal cycling characteristics, thereby providing long-term reliability and performance.
