Feed Through Capacitors are components which are typically used in microwave and RF systems for the purpose of providing a low frequency/high C path from one side of an electromagnetic component or transmission line to the other. This type of capacitance is typically used in the RF stages of a radio receiver, or as a low pass filter in a signal path. The SFUMC0500333MX0 is a mica-based, feed thru capacitor designed to provide dual-layer, low frequency, high-C performance for use in RF systems.

The SFUMC0500333MX0 feed thru capacitor consists of two sets of mica-based, low frequency, high C electrodes which are also available with Ni plating for thermal performance. The electrodes are inserted into two identical voids laying atop one another with a spacing of 0.005mm. The capacitor is then sandwiched between two mica sheets for increased thermal and electrical stability. The top sheet is then sputtered or plated for additional insulation, if desired. The overall package is typically less than 0.2″ in size.

The working principle of the SFUMC0500333MX0 is based on the principle of direct current conduction. In this case, direct current is passed through the two sets of mica-based electrodes which produce a differential voltage across them. This voltage creates a current through the capacitor via internal leakage, and produces a certain C value. The amount of C present is determined by the total area of the electrodes and the spacing between them.

Due to its low frequency and high C performance, the SFUMC0500333MX0 is used in a wide variety of applications. In radio receivers, the component acts as a low pass filter for selective frequency discrimination. It is also commonly used in signal mixing circuits, as well as in power regulator circuits. Additionally, feed thru capacitors such as the SFUMC0500333MX0 are used in various other RF applications such as phase shifters, signal generators, signal converters, and pulse detectors.
