Feed Through Capacitors

A feed through capacitor, such as model B85121A2475A630, is a type of high-frequency electrical component mainly used in high-frequency circuits, such as for signal filtering and decoupling of signal lines. It is usually used to block out-of-band signals and reduce electromagnetic interference.Feed through capacitors are widely used in all sorts of electronic systems associated with the transmission of signals, such as in wireless communication, data processing, and analog circuitry. They are also extensively used the military and aerospace industry for applications such as high-performance radar systems.The working principle of a feed through capacitor is quite simple. The capacitor consists of two metal plates that are separated by an insulating layer of material, usually some kind of ceramic. When a signal is applied to the capacitor, the current flows through the ceramic material and builds up a charge on the plates. This charge acts as a filter for the signal, attenuating any unwanted frequencies outside the desired pass band. The capacitance of the capacitor determines the effectiveness of the filter as it controls the range of frequencies that are blocked and passed. It is important to choose the right feed through capacitor for the intended application, as some are designed for higher frequency ranges than others. The model B85121A2475A630 feed through capacitor in particular is designed for frequencies up to 10GHz. It has a capacitance of 2.475pF and a maximum voltage rating of 1000VRMS. Its package creates an ESD safe connection to signal conductors and its solderless terminals ensure that the connection cannot be overloaded. In addition to its ESD protection, the B85121A2475A630 also provides improved radio frequency signal filtering. It has a high dissipative current rating of 4A(rms) which increases the tolerance of the capacitor, ensuring low losses even in high current applications.Overall, the model B85121A2475A630 feed through capacitor is an excellent choice for high frequency filtering applications due to its high frequency range, high dissipative current rating, and ESD safe connection.
