Fixed Inductors

A fixed inductor, often referred to simply as an inductor, is an electrical component consisting of a coil of wire wound around a core to store energy in a magnetic field. Fixed inductors are used in many types of electronics, including power supplies, signal processors, amplifiers, and data transmissions.

The T1812-270J fixed inductor is designed for power supply and power supply-related applications. It can handle frequencies ranging from 20kHz to 3Mhz in a variety of operating temperatures. The internal construction of a T1812-270J inductor consists of a toroidal core made of ferrite material, a wound wire of copper, and a protective coating of varnish.

The T1812-270J can be used in both regulated and switching power supply designs. In a regulated power supply, it can be used to filter unwanted noise and reduce ripple from the output. In a switching power supply, it functions as an inductor in a switch mode application. The inductor is designed to reduce the voltage spike when the power switch is turned on and off.

The working principle of the T1812-270J fixed inductor is based on the law of induction, which states that a coil of wire carrying a current produces a magnetic field. The magnetic field stores energy, which is released when the current is stopped. The T1812-270J inductor acts as a filtration device, allowing only the desired frequencies to pass through while blocking out unwanted noise.

Fixed inductors like the T1812-270J are an essential component for any electronic design. They provide filtering and regulation for power supplies, signal processing, and data transmissions. With its wide operating frequency range and ability to handle temperatures ranging from -40 to 85°C, the T1812-270J is a reliable and versatile choice for any power supply design.
