Feed Through Capacitors, or FTCs, are components designed to pass radio frequency (RF) signals between two points on a Printed Circuit Board (PCB).

SFKKC5000680MC0, from CDE/Cakewalk, is one such device. Feed Through Capacitors are usually used to connect various stages of a radio system, since they offer a low-impedance connection that facilitates the flow of the signal, while simultaneously reducing interference.

The exact application field of the SFKKC5000680MC0 depends on the type of PCB design. Generally, this device functions as the main connector between a transistor stage or amplifier stage and the antenna array on a PCB. In addition to RF signals, it can also be used to connect general digital or analog signals, as well as coax cables.

The main working principle of the SFKKC5000680MC0 centers on two principles: capacitive coupling and coupling fields. It utilizes a capacitor as the main component of the device. This capacitor sends alternating current (AC) signals through two inner electrodes and one external electrode. A dielectric material separates the inner electrodes, ensuring that the electric current is completely regulated.

It is important to note that the inner electrodes of the capacitor are designed specifically for low-impedance signals. This is one of the reasons why this device is so effective in connecting radio stages and avoiding interference from other signals. The outer electrode, on the other hand, is designed to transfer high-impedance signals.

The other major working principle at work in the SFKKC5000680MC0 is coupling fields. This particular device makes use of two different overlapping electromagnetic fields, both generated by the inner and outer electrodes of the capacitor. By connecting these two fields, the SFKKC5000680MC0 uses capacitive coupling to create a connection that is less susceptible to interference.

In essence, the SFKKC5000680MC0 works to effectively minimize RF signals between two points on a PCB. The combination of capacitive coupling and overlapping electromagnetic fields allows it to achieve this task while avoiding interference from other signals. In this way, this particular Feed Through Capacitor device can be indispensable for circuit board designers who need to transmit RF signals with minimal signal degradation.
