EMI/RFI filters typically come in two varieties: LC networks and RC networks. In this instance, FK2125T407AL-T is an RC network. This filter reduces unwanted signals and allows desired signals to pass through.

Application Field of FK2125T407AL-T

FK2125T407AL-T is most commonly used in automotive powertrains. It is designed to reduce noise interference generated by the electronic controlled units (ECUs) of the engine and transmission systems. This filter also reduces interference generated by capacitor discharge events during water pump rotation control.

The FK2125T407AL-T is also commonly used in powertrain control of trucks and large vehicles. Installations usually include power supply, ECUs/ECMs, sensor connections, and signal input/output connections. The FK2125T407AL-T filter is designed to help reduce the EMI noise generated from those components and can help to ensure high signal integrity.

Working Principle of FK2125T407AL-T

FK2125T407AL-T uses an RC network to reduce interference. This filter works through impedance matching, providing a low resistance path to ground for high frequency signals while presenting a high resistance path for lower frequencies. The RC network is designed to provide a high degree of attenuation for signals in the high frequency range, while allowing low frequency signals to pass through with minimal distortion.

The two components of the RC network are the resistor and capacitor. The resistor works to reduce the amount of current that can pass through the circuit. The capacitor, on the other hand, stores and releases electrical energy, which helps to limit the amount of voltage that can be transmitted through.

The components of the RC filter are connected in series. This means that, when a signal is applied, the RC network will reduce the amplitude and phase of the signal before it is passed through to the connected circuits. This helps to reduce or eliminate interference in the system.

The working principle of the FK2125T407AL-T RC network filter is the same for both types of systems discussed above. However, the components of the filter may differ depending on the application. The components of the filter are designed using a simulation program, such as SPICE, and the components can be customized for specific applications.

Conclusion

FK2125T407AL-T is an RC network filter designed to reduce EMI noise in powertrain systems. This filter works by providing an impedance matching system, which presents a low resistance path to ground for high frequency signals while presenting a high resistance path for signals in the lower frequency range. The RC network filter is designed to reduce or eliminate interference in the system and can be customized for specific applications.
