Film capacitors are polarized capacitors, generally constructed using one or more films of non-conductive plastic-based dielectric material, such as polyester, polypropylene, polystyrene, or polycarbonate. The most common type of film capacitor is the polyester capacitor, sometimes called a Mylar capacitor, though it is usually made out of polyethylene terephthalate (PET). While capacitors made with multiple dielectric layers may yield higher capacitance values compared to other types, their relatively large physical size and high price limit their usage.

185393J100RCB-F is a film capacitor also known as “F-Mylar” or “Polyester Film Capacitor”. Polyester film capacitors are constructed with an outer plastic sleeve and a disc of dielectric material which acts as the dielectric layer to form two stiff electrodes. The outer sleeve is a polyester film that is covered with aluminum or copper coating which acts as the electrode. The two electrodes are easily separated due to the dielectric layer that separates them. The dielectric layer is made from a thin layer of plastic which makes it very lightweight and easy to handle. In addition, the polyester film capacitor is polarization-free making it the ideal choice for applications with polarity sensitive factors.

185393J100RCB-F’s application field mainly covers audio applications, where it is used as a high frequency filter. Its high frequency characteristics make it ideal for use in the crossover stage of audio systems, as well as for use in high frequency power amplifiers. The polyester film construction gives it superior audio frequency performance compared to other types. It also has superior insulation resistance and low temperature coefficient, making it suitable for use in any harsh temperature environment.

The working principle of the 185393J100RCB-F is based on the concept of capacitance. When a voltage is applied across the electrodes, electric field is created which attracts the electrons from one of the electrodes and repels them from the other. This causes a charge separation which generates a field that opposes the current flow, producing the phenomenon known as capacitance. The dielectric material between the two electrodes determines the size of the capacitance. The higher the dielectric constant of the material, the higher the capacitance.

The 185393J100RCB-F has a frequency range of a maximum of 10,000 Hertz (Hz) and a temperature range of -55 degrees Celsius to +85 degrees Celsius. The capacitance value varies from 10pF to 1000pF, while the working voltage is 100VDC. With its wide operating range and high frequency performance, the 185393J100RCB-F gives superior audio performance and is a high-value choice for audio application fields.

In conclusion, the 185393J100RCB-F is a polyester film capacitor which is ideal for use in audio applications requiring high frequency performance. Its low temperature coefficient and insulation resistance make it suitable for any harsh environment. The range of capacitance values and operating voltage make it a reliable choice, while its high frequency performance makes it a great choice for high-end audio applications.
