4379-221KS

Inductors are devices which can provide impedance without the need for a physical motion, instead using the principles of electromagnetic induction. Such inductors are used in a wide range of applications, including communications, medical equipment, telecommunications, automotive electronics, and industrial automation. The 4379-221KS application field and working principle are two of the more commonly used types in this field.

The 4379-221KS is a radial-leaded inductor made by Pulse Electronics. Its main application fields are active filters on switching regulators, DC/DC converters, and in power line topologies such as cascode. The inductor is made using ceramic powder and ferrite rods, and typically operates at a voltage of 300V. It has a current rating of 0.18A, and an inductance value of 220mH.

The working principle of the 4379-221KS inductors is based on the concept of transformer action. When a current passes through the primary coil, an alternating magnetic flux is created which generates a voltage in the secondary coil. This principle is used to create a frequency-dependent impedance in the circuit, since the inductor acts as an impedance element whose magnitude is frequency-dependent. This frequency-dependent impedance means that higher frequency signals are blocked while lower frequencies can be passed through.

The 4379-221KS induction can also be used in conjunction with capacitors to create frequency-selective filters. The inductor and capacitor together form a resonant circuit which has both capacitive and inductive elements in it. This means that low frequency signals will be rejected while higher frequencies will be amplified. This makes the 4379-221KS ideal for use in active filter circuits.

The 4379-221KS is a versatile inductor which can be used in many different applications. It can be used to filter signals, reduce noise, and provide impedance in switch-mode power supplies. This makes the 4379-221KS an essential component for many different projects. With its robust construction and low profile design, the 4379-221KS is a popular choice for a variety of applications.
