Feed Through Capacitors are an important part of electronic circuitry. They are used to route signals, dampen noise, and provide shielding for different components of a circuit. B85121A2504A630 is a type of such capacitor, which are specially designed to provide better performance and protection against noise, transient voltages, and unwanted electromagnetic interference (EMI). This article will discuss the application field and working principle of B85121A2504A630.

B85121A2504A630 is mainly used in power supply circuits and switch-mode power supplies. In power supply circuits, it prevents interference from reaching sensitive components within the circuit by blocking the conducted and radiated EMI noise. In switch-mode power supplies, it stabilises the output voltage by providing smoothing and filtering of high frequency noise, as well as maintaining a constant input voltage. It also helps to reduce the power loss by limiting the ringing of the transformer.

The working principle of B85121A2504A630 is based on the idea that impedance is inversely related to frequency. This means that at lower frequencies, the impedance is higher, while at higher frequencies, the impedance is lower. Thus, this capacitor is designed to have a high impedance at lower frequencies while providing a low impedance at higher frequencies. This allows it to attenuate or block signals in the higher frequencies while preserving signals at lower frequencies. As a result, it is very effective in preventing undesired noise from disrupting or damage sensitive components in the circuit.

In conclusion, B85121A2504A630 is a feed through capacitor used in power supply circuits and switch-mode power supplies. Its working principle is based on the concept of impedance, whereby it has a higher impedance at lower frequencies and a lower impedance at higher frequencies, thereby attenuating or blocking signals from high frequency signals while preserving lower frequency signals. This makes it very effective in providing protection against interfering noise, transient voltages, and EMI.
