Introduction

Film capacitors, commonly known as metallized film capacitors, are a type of capacitor that uses metalized film as the primary material for its capacitance. Compared to traditional electrolytic or non-polar electrolytic capacitors, film capacitors offer much higher capacitance, longer life expectancy, and greater stability under harsh environmental conditions such as extreme temperature, shock and vibration. The CB262E0225JBC is a metallized film capacitor specifically designed for automotive applications.

Application Field

The CB262E0225JBC film capacitor is well-suited for a wide range of automotive applications, such as ignition systems, fuel injection systems, and anti-lock braking systems. Other applications include power supplies, line filtering in audio systems, and overvoltage protection.

Design and Construction

The CB262E0225JBC film capacitor is composed of a metalized polyethylene terephthalate (PET) film as the dielectric material. The film is rolled onto a strong, non-magnetic aluminum frame. It is then impregnated with silicone-based oil to help its durability and to help reduce noise and capacitance loss. The capacitor is then encased in a thermoplastic UL94V-0 epoxy shell for protection against dust, moisture, and other environmental elements.

Working Principle

Film capacitors, including the CB262E0225JBC, are based on the principle of capacitance. This is the ability of an electrical circuit to store energy or charge due to the presence of two electrical charges on either side of a dielectric material. The CB262E0225JBC is made from a metalized film material, which is an excellent dielectric material with significantly higher capacitance than other types of capacitors.When a voltage is applied to the film capacitor, it causes an electric charge to accumulate on both side of the dielectric film, which creates an electric field between the two plates. This electric field allows for the electric charge to be stored, and for the capacitor to store an electric charge. The charge is then able to be released back through the electric field as a current when the voltage is removed.

Conclusion

The CB262E0225JBC metallized film capacitor is an ideal choice for applications requiring a high capacitance value, excellent performance in harsh environmental conditions, and long life expectancy. With a wide range of automotive applications, the CB262E0225JBC can be used in a variety of applications, from automotive fuel injection systems to audio line filtering. By using the principle of capacitance, the CB262E0225JBC film capacitor can store and release electric charges, providing the desired output.
