Feed Through Capacitors

Feed through capacitors refer to special type of electrical components designed to transmit electrical current from one side of a printed circuit board (PCB) to the other side. In this context, the term ‘feed-through’ typically relates to the direct path of current from one component of the board to of another component within the same PCB. They are often used in a wide range of applications, from mobile phones to digital cameras, and as such, are becoming increasingly popular.

One such feed-through capacitor is the 4403-039LF. This capacitor is noted for its small dimensions, low profile design, and its high current handling capabilities, making it ideal for applications where space is at a premium. In addition, the capacitor is also flexible and robust, thanks to its SMT (Surface Mount Technology) construction, making it suitable for use in harsh environmental conditions.

To understand the working principle of the 4403-039LF, it is first necessary to understand its external construction. The capacitor consists of a cylindrical capacitor housing, surrounded by a dielectric material that helps keep the capacitance constant. Furthermore, the capacitor also has a pair of metalized conductors at each end which connect to the PCB’s conductors. These connect to the other components of the board and allow for the effective and efficient transmission of electrical current.

In terms of application fields, the 4403-039LF capacitor is ideally suited for high-frequency signal applications, such as for radio broadcast and telecommunication systems. This is due to the high speed of the electrical current that the capacitor can handle, which makes it ideal for these types of high-bandwidth applications. Additionally, the capacitor is also often used in the manufacturing of many types of medical equipment, as it is capable of withstanding high temperature and humidity conditions, making it well-suited for use in various medical environments.

Overall, the 4403-039LF is a versatile and reliable feed-through capacitor that can be used in a wide range of applications. Thanks to its small size, high current carrying capabilities, and its robust construction, this capacitor can be used in a variety of industrial, commercial, and medical applications. Furthermore, the capacitor’s external construction helps keep the capacitance constant over time, ensuring that it remains reliable and stable during operation.
