Film capacitors are widely used in electronic circuits due to their small size, good stability, and high performance. The 32FD3701 is a film capacitor that is designed for high-power applications. It is available in two types – motor and ultra-wide band, and can support a wide range of temperatures. This article will discuss the application field and working principle of 32FD3701.

Application field of 32FD3701

The 32FD3701 is designed for use in low frequency electrical conversion and filtering applications. It is commonly used in motor and ultra-wide band circuits, as well as various RF applications. It is also used in automotive electronics, medical devices, and communications.
The 32FD3701 can be used in both AC and DC applications, and can operate in temperatures ranging from -40°C to +105°C. It has an insulation class of F (105°C rated) and a capacitance range of 0.1pF to 0.1uF.

Working principle of 32FD3701

The 32FD3701 is a film capacitor with an inter-layer electrostatic insulation structure. It uses two dielectric layers to create a high-capacity electric field across the core. The core consists of a polyester film and an electrolytic coating on both sides. At the edges of the core, two electrodes are connected to the capacitor body, which can be connected to an external circuit. When an electric current is applied, the electric field between the two layers creates a charge separation, which in turn creates a capacitance effect.
When a voltage is applied to the electrodes, the fields align and electric current flows through the core. The capacitor then charges and discharges, creating a pulsed electric current. This current can be used to power an electrical device, or used for signal filtering in an audio circuit. The capacitance of the 32FD3701 is relatively constant, even over a wide range of temperatures, frequencies, and voltages.
