Fixed Inductors: 4379-472ks Application Field and Working PrincipleFixed inductors are an integral part of many electrical and electronic circuits, and the 4379-472KS is no exception. To understand the wide range of applications and workings of the 4379-472KS, it helps to understand more broadly what fixed inductors are, what they do, and how they differ from other types of inductors.Fixed inductors are types of electrical components that store energy in the form of an electric current in a coiled wire or other conductor. Fixed inductors have a core made of ferromagnetic materials, such as iron or steel. This core creates an “inductive field” around the coil. When electric current is passed through the coil, the inductive field causes the coil to have a higher voltage than the applied current. This is known as “inductor reactance.” This effect is used to produce voltage regulation, filtering, impedance matching, and damping.The 4379-472KS is a specific type of fixed inductor, designed to reduce electrical noise. It is made of a molded, non-magnetic core, which is designed to proficiently absorb external magnetic fields. The 4379-472KS has a high inductance value of 0.0015 mH and a low DC resistance of 0.2 ohm, which make it very efficient and reliable at suppressing noise.The primary application of the 4379-472KS is to reduce the level of electrical interference (EMI), which can interfere with the functioning of other devices that rely on radio communications. The 4379-472KS is a widely used choice in automotive, industrial, marine, telecom, and other applications which depend on reliable radio communication. Additionally, the 4379-472KS is often used in handheld devices to suppress the “cell phone hum” caused by wireless interfering with the internal circuitry of the device.The 4379-472KS is also used in any application requiring high current and low voltage isolation, such as servers, firewalls, and other networking hardware. Its high inductance, low DC resistance, and high temperature rating make it an excellent choice for shielding circuits from noisy external electric signals.The working principle of the 4379-472KS is quite simple, and is based on the principles of inductance. As previously mentioned, it employs an inductive field which causes the coil to have a higher voltage than the applied current. This causes the inductor to resist changes in spectral frequency, resulting in a more stable electrical system. This helps to ensure that the desired frequencies are kept in balance, and that other frequencies are isolated or received at reduced amplitude, which is essential for efficient functioning of high-end electrical systems.In conclusion, the 4379-472KS is an excellent choice for suppressing electrical interference and eliminating "cell phone hum" in many applications. Its combination of high inductance and low DC resistance makes it especially suited for eliminating noise and maintaining a stable electrical system. Its application field spans automotive, industrial, marine, telecom and many other areas, and its ease of use and simple working principle make it an accessible and reliable choice for many applications.
