Feed Through Capacitors

Feed through capacitors, also known as bypass capacitors, are electrical components used to couple high frequencies while blocking DC and lower frequency signals. They possess an ohmic resistance into which signal current flows and a capacitance that stratifies the frequency spectrum of the voltage signals. This allows for the bypassing of high frequency or unwanted signals to ground while allowing DC and lower frequency signals to pass through the capacitor to its intended destination. In this way, feed through capacitors are used to filter signals in both analog and digital circuits. The 54-874-016 feed through capacitor is a high frequency, temperature-stable, low profile, low ripple, and efficient capacitor specifically designed for the high frequency (>1 GHz) industry. It is available in two sizes – a 5 pins and a 3 pin version – with a capacitance of 0.22uF ± 10%. A feedthrough capacitor is divided into two parts – a two lead capacitor with a central hole – which facilitates the passage of the signal – and a metal tab embedded on the circumference of the capacitor shaft. This tab provides electrical connection for isolating the joint between the two parts. The 54-874-016 feed through capacitor consists of a metalized Ceramic Dielectric with a built-in capacitor, which is usually operated at a high frequency. The capacitor also includes a temperature stable dielectric, a plating layer and a metal housing with tab that facilitate sharp signal control. This feedthrough capacitor provides excellent temperature stability and low ESR, making it suitable for multiple applications.The working principle of the 54-874-016 feedthrough capacitor is relatively simple. It consists of two metallic conductors (the capacitor’s plates) and a non-conducting material (dielectric) between them. When a voltage is applied across the capacitor, electric field lines are created in the dielectric material. This creates a capacitance which, in turn, stores electrical energy in the form of an electric field.The primary application for the 54-874-016 feedthrough capacitor is in the transmission of high-frequency signals. Due to its improved temperature stability, the capacitor is optimal for high-speed digital applications. Its metal tab is excellent for providing quick and reliable connections in automated production systems and equipment. The 54-874-016 capacitor is perfect for use in communication-, medical-, and automotive applications as well as other high-frequency applications.In conclusion, the 54-874-016 feedthrough capacitor is an efficient electrical component perfect for filtering signals in both analog and digital circuits. It consists of a metalized ceramic dielectric and a plating layer. Its metal tab provides electrical connection for isolating the joint between the two parts. The primary application for the feedthrough capacitor is in the transmission of high-frequency signals - making it perfect for communication-, medical-, and automotive applications.
