Introduction to Film Capacitors

A Film Capacitor, also known as a plastic film capacitor or dielectric film capacitor, is a type of capacitor that uses a plastic film as the dielectric material. This type of capacitor has a wide range of applications in various electrical and electronic devices, making it a popular choice among engineers and designers.

The Benefits of Film Capacitors

The benefits of using film capacitors are numerous, including: High insulation resistance, resulting in very low leakage current; Low ESR, meaning that they can handle high frequency noise; Low tolerance – typically better than 1% for standard film capacitors; Low Drifting – Film capacitors have good temperature coefficient stability; Excellent reliability – Film capacitors can usually operate for very long periods of time with minimal degradation; High voltage capability – Many film capacitors are available in high voltage ratings; Ease of use – Film capacitors are usually ready to use out of the box; Low self-heating –Capacitors use a plastic film as the dielectric material and a metal foil as the electrodes, resulting in a low self-heating behaviour; Low dissipation factor – Film capacitors have a high resistance to the flow of alternating current. This reduces the level of power losses in the capacitor.

CB037E0473JBA Application Field and Working Principle

The CB037E0473JBA is a film capacitor with a 473 voltage and 0.033UF capacitance. This type of capacitor is suitable for most general electronics applications, including power supplies and filtering.The working principle of the CB037E0473JBA film capacitor is based on the dielectric principles of electric fields charged particles. When a current passes through the capacitor, the electrically charged particles produce a stored electric field, or charge. The stored charge produces a voltage across the two terminals of the capacitor. This voltage is largely determined by the capacitance and the resistance of the dielectric material. The resistance of the dielectric material determines the rate of discharge into the external circuit and is measured using the dissipation factor.The CB037E0473JBA capacitor is constructed using a film of plastic insulator sandwiched between two metal foil electrodes. This film is composed of two layers of oppositely charged particles which create the capacitance. The capacitance and voltage rating is primarily determined by the thickness of the plastic film. The foil electrodes are also connected to terminals which are used to connect the capacitor in an external circuit.

Conclusion

The CB037E0473JBA is a film capacitor that is suitable for many general electronic applications. This type of capacitor is appreciated for its low ESR, low self-heating, and wide voltage rating. The working principle of the capacitor is based on the dielectric principles of electric fields charged particles, which store the charge and produce a voltage across the two terminals of the capacitor. The capacitance is primarily determined by the thickness of the plastic film and the resistance of the dielectric material determines the rate of discharge into the external circuit.
