• MS75085-12BH Fixed Inductors: Application Field and Working Principle



MS75085-12BH fixed inductors, also known as EMI suppression filters, are common electronic components used to suppress electromagnetic interference on a variety of circuits. It functions as a combination of an inductor, capacitor, and sometimes an inductor in order to form an EMI filter network. This type of inductor is available in surface-mount configuration & solder feet, and is designed for filtering high-frequency EMI signals.



• Application Field

MS75085-12BH fixed inductors are used to reduce radio-frequency interference in various consumer electronics such as cell phones, computers, televisions, DVD players, and digital music players. Using these inductors makes electronic circuits more robust and reliable, as it reduces the risk of the circuit experiencing interference from outside sources. Additionally, MS75085-12BH fixed inductors are often used in battery-powered devices to stop electrical signals, including signals from multiple sources, from leaking to and corrupting the battery power. Moreover, these inductors are used in power systems, such as automotive applications and switching power supplies, to limit noise that can lead to component failure.



• Working Principle

The working principle of MS75085-12BH fixed inductors is based on the concept of electromagnetic induction. Electromagnetic induction occurs when an electric current is passed through a conductor like an inductor. This creates an electromagnetic field around the inductor, which induces an electrical current in other conductors nearby. When this current flows, it will cause a voltage in these other conductors which can disrupt the original electrical signal. As such, MS75085-12BH fixed inductors are used to limit these induced electrical signals. When the inductors are placed in series with the circuit, they create a magnetic field which opposes any induced voltage that is causing interference, thus reducing or completely eliminating the disruption. Furthermore, these inductors are also used to reduce or prevent power supply noise, which can be caused by insufficient power supply decoupling, capacitors that are too small to handle the current, and improper grounding.



• Conclusion

MS75085-12BH fixed inductors are a versatile and essential part of many electronic circuits. They are used to reduce EMI signals, prevent voltage disruptiion, and limit power supply noise. As such, these inductors are essential components for the proper function of various electronics.
