Feed Through Capacitors, such as the B85321A2405A401, are used in a variety of applications. In its simplest form, a feed through capacitor is a two-terminal device that is used to bridge two different circuits.

The main purpose of a feed through capacitor is to provide an AC signal path to ensure that the AC signals are isolated from one section of the circuit while allowing the passage of DC signals as well. This is achieved through the use of a capacitive element, which acts as a low-pass filter. This filter allows the AC signals to pass through the capacitor, while blocking the DC signal from the other section of the circuit.

The B85321A2405A401 is a feed through capacitor that has a wide range of applications. It can be used in automotive, telecommunications, audio, and industrial applications. The device has a design temperature range of –40 to +85°C and is designed for a rated operating voltage of 125VAC and a current of 2A.

The B85321A2405A401 is a two-terminal device, with a housing that is made of dielectric material such as polyacetal. This housing contains a sealed capacitor element that works in tandem with a dielectric material that functions as a dielectric base. This base is a metalized film, which serves as the insulation that separates the two terminal points.

The capacitance of this device is specified according to its effective capacitance value. The effective capacitance is determined by the area of the dielectric material, the thickness of the dielectric, and the distance between the two terminal points. The B85321A2405A401 has a capacitance of 0.047μF and a capacitance tolerance of ± 10%.

The working principle of feedthrough capacitors is based on electrostatics or capacitance. As the voltage is applied across the two terminals, the electrostatic charge between the two metal surfaces is increased. As this charge increases, it causes the capacitance of the device to increase and the voltage between the terminals to decrease. This increase in capacitance is what allows the AC signals to pass through the device while blocking out the DC signals.

The B85321A2405A401 is an excellent choice for applications where a reliable and efficient way to create an AC signal path is needed. The combination of its operational versatility and its low capacitance tolerance makes this feed through capacitor an ideal choice for applications ranging from automotive electronics to telecommunications and even industrial purposes.
