Feed Through Capacitors, or FTCs, are electrical components used in many applications ranging from RF filtering to EMI suppression. The 54-786-013 from Standex Electronics is a specialized feed through capacitor designed to provide excellent RF immunity in the same package. It incorporates a unique construction technique that uses glass-filled sintered polyethylene core and stainless steel shell to form a dependable, hermetically sealed unit that can withstand temperatures of up to 150°C. The device also features an integrated internal discharge network to ensure safe transient operation.

This particular device is capable of providing excellent RF filtering with a rated frequency of 1 MHz and a bandwidth of 100 to 1750 MHz. It also offers a wide operating temperature range of -45 to 150°C and an operating voltage of up to 250 volts. In addition, it features a low capacitance value of 0.007 to 0.01 nanofarads and a maximum pulse current rating of 50A.

The 54-786-013 Feed Through Capacitor works on the principle of capacitive voltage division. When the capacitor is connected to an AC power source, the alternating current flows through the capacitor. This creates a voltage division across the capacitive plates, with the voltage across the capacitor plate being lower than the source voltage. This voltage differential is known as reverser voltage and is suitable for use in a variety of applications

For example, the 54-786-013 device can be used as a high-frequency filter. In this application, the capacitor acts as a shunt to block high-frequency signals while passing low-frequency signals. This allows one to achieve efficient filtering and prevent the insertion of unwanted noise into the system. The device can also be used to attenuate RF signals, thus preventing electrical interference from causing damage to sensitive components or hinder operation.

The characteristics of the 54-786-013 Feed Through Capacitor also make it suitable for use in impedance matching applications. By connecting two or more capacitors in series, a low-impedance network is created which can match the impedance of the system. This can be used to reduce power losses in RF transmission lines or to increase the efficiency of the system.

The 54-786-013 Feed Through Capacitor is ideal for applications requiring low-cost RF filtering solutions with superior performance. Its combination of high-frequency filtering, EMI/RFI shielding, low power dissipation, and wide operating temperature range make it an excellent choice for many applications. Its robust construction ensures reliable operation even in the toughest environments.
