Film capacitors, also known as plastic film capacitors, metalized film capacitors, film dielectric capacitors, and polyester capacitors are electrical components constructed with a thin sheet of plastic film as the dielectric, and deposited metal electrodes on each side that functions as the electrodes of the capacitor. While they have considerably high capacitance per volume - they can be just a few millimeters thick while maintaining a relatively high capacitance meter, they are also widely used in many industrial applications.

About 104PSB302K2J

The 104PSB302K2J is a silver plated PET polyester film capacitor with a 0.68µF, 1000Vdc capacity. It is designed specifically to help reduce electrical noise from electronic or automotive gear. Due to its special design, this component offers both durability and stability in various operating conditions, making it suitable for demanding automotive, industrial and telecom applications.

Application fields

The 104PSB302K2J offers a range of potential applications in different industries. This includes automotive, industrial, telecom and consumer electronics. One of the primary uses for the component is in automotive and marine applications, where it is used as a noise suppression tool. In such scenarios, it is typically connected between the electronic parts of the equipment and the body of the vehicle in order to reduce interference.

Similarly, the part can also be used in audio components. Its silver plating helps to reduce the resistance, and the capacitor also helps to prevent interference. It can also be used in industrial equipment motor control, where it provides the necessary smoothing of the DC current for successful operation. In addition, consumer electronics like televisions and computers often utilize the 104PSB302K2J for controlling the voltage that is supplied to the equipment. The component helps to regulate the device and protect it against power surges, preventing potential damage.

Working Principle

When placed in alternating current (AC), the 104PSB302K2J functions as a low-pass filter. This is due to the thin plastic film acting as the dielectric of the capacitor and aiding in the transmission of electric charge. When a certain level of voltage is supplied to the capacitor, such as that of a lightning strike, then this voltage will be witnessed across the device\'s electrodes.

The capacitor will then start to store energy and prevent further surges in voltage. This helps to protect the other components connected to the device from prolonged exposure to such high levels of voltage. This is also known as its protection functionality.

In addition, capacitors also have another use known as decoupling. This helps to reduce electrical and magnetic interference within the circuit by effectively “smoothing” out the waves, allowing direct current (DC) to pass through while resulting in less stress on other components, as well as higher levels of accuracy and better overall performance. This is advantageous in some applications where precision is essential.

Conclusion

The 104PSB302K2J is a specialised silver plated 0.68µF PET polyester film capacitor, suitable for a variety of industries. It has a wide variety of uses, from automotive and marine applications to consumer electronics and audio components. Its specialised design and construction provide it with a range of advantages in terms of protection against power surges, as well as providing smooth and noise-free current flow.
