Fixed Inductors

SWS-0.68-377 Application Field and Working Principle

Inductors, often referred to as coils or chokes, are passive circuit components that store energy in the form of magnetic fields. They are essential in many electronic applications, including filters, impedance matching, signal conditioning, and voltage regulation. They can come in either fixed or variable forms and the fixed form inductor gives a very stable performance over operating temperature. The SWS-0.68-377 Fixed Inductor is a chip type inductor made of ferrite materials with a maximum size of 5mm x 5mm x 1mm. The SWS-0.68-377 fixed inductor has three main application fields, namely, cellular phones, PDAs, and laptop computers. It has good RF shielding characteristics and low DC resistance, making it the preferred component when the space in the printed circuit board (PCB) needs to be conserved. It also has high inductance and can accurately and effectively filter out unwanted RF signals. In cellular phones, the SWS-0.68-377 fixed inductor is usually used to filter out spurious EMI signals, while its RF shielding characteristics prevent AC leakage. In PDAs and laptop computers, the inductor can be used to reduce switching noise in power supplies, thus ensuring that the signal remains clean and stable.The working principle of the SWS-0.68-377 is closely related to the principles of magnetism and electromagnetic induction. When electrical current is passed through a conductor, a magnetic field is created around it. This is known as the inductor effect. In a fixed inductor, this effect is used to create an inductance or resistance against the current flow, also known as impedance. In the SWS-0.68-377, the magnetic field created by the electrical current induces an opposing current in the neighbouring conductors. This opposing current also creates a magnetic field, thus reducing the overall flow of current. The amount of resistance depends on the number of windings and the types of materials used.The SWS-0.68-377 has a power rating of 500mW and is capable of working up to a temperature of +125°C. It is available in both surface-mount and through-hole varieties, and can be used in a variety of applications due to its small size and low resistance.Overall, the SWS-0.68-377 Fixed Inductor is a great choice for applications that need portable power sources or RF shielding solutions. Its compact size makes it a great choice for a range of applications, and its low resistance and high inductance make it suitable for a variety of devices.
