Fixed Inductors

1944R-17G Application Field and Working Principle

Fixed inductors, also known as non-variable inductors, are electronic components with the purpose of inducing electrical current in devices using magnetic fields. They are commonly used as filters and to store energy, which can then be used in the electronic design of many everyday products and systems that require precise frequency control or in electrical power applications requiring a high degree of efficiency.

The 1944R-17G is a high performance, low-cost fixed inductor from Peregrine Semiconductor corporation. It is designed for a wide range of applications that require a stable magnetic field. Some of the main applications for this inductor include power supply regulation, power factor correction, dynamic braking, mobile communications, and motor control.

The 1944R-17G fixed inductor has a power rating of 17.4A with a nominal inductance of 1.458 μH. It has an operating temperature range from -20 to +95 degrees Celsius and is designed with a molded ferrite core. The inductor has a rated resistive current of 17A and a bias current of 1A. The inductor is also designed to provide a low core loss of 0.035W/xA, which makes it suitable for switching power supplies and other high current applications.

The working principle of a fixed inductor is basically the same as that of any inductor. By creating a magnetic field, the inductor induces an electrical current. When an AC signal is applied to the inductor, it will cause the inductance value to change over time, creating a counter electromotive force or “back EMF”. This back EMF is then used as the opposing source of current, and the resulting current is then used as the output.

The 1944R-17G fixed inductor has a wide operating temperature range and it is designed to work in a variety of harsh environmental conditions. The inductors are designed for a long operating life, and they have been designed for higher efficiency and reliability. It is also designed to provide a high accuracy in current regulation and its low core loss allows it to be used in many applications that require energy efficiency.

In conclusion, the 1944R-17G fixed inductor is a high-performance, low-cost component used in many applications. It is designed for a wide operating temperature range and provides reliable and efficient current regulation. The inductor is also designed to provide low core loss, making it suitable for use in many high current applications. It is an ideal choice for a wide range of electronics applications.
