Fixed inductors are passive electronic components which can store electric energy by magnetizing bridges in electric current. They are one kinds of inductors used in switching power circuits, radio frequency circuits, filter circuits and oscillator circuits. Among many types of fixed inductors, 0402-9N0K is a popular one for its outstanding performance.

The 0402-9N0K fixed inductor has maximum DC resistance of 0.4 Ohm and maximum Q-rating of 105. It is produced in the 0402 package form you can recognize it by its size which is 0.04 inches long and 0.02 inches wide. It can handle power from 2.5 to 8.5 Watts and is made of ceramic material.

The application area 0402-9N0K fixed inductor is quite wide. It is designed for switching power circuits and so it can be used in portable and laptop computers, mobile phones, IR remote controllers, digital cameras and other consumer electronics.

These inductors are widely used in pulse and filter applications. They offer excellent inductance stability over wide temperature range and higher Q-factor makes them an ideal choice for high frequency applications. They also have much higher reliability than low-cost wire-wound inductors. That makes them perfect for use in automotive, space and medical related applications.

The working principle of 0402-9N0K fixed inductor is based on Faraday\'s Law of Induction. When AC or DC signal is applied, electric current generate magnetic flux which induces a voltage across the inductor. The voltage is proportional to the rate of change in electric flux. This voltage can then be used to generate or store energy.

Fixed inductors produced in 0402 package provide efficient and reliable performance for many applications. 0402-9N0K can handle higher working temperatures and has higher current rating compared to other similar products. Its wide application range and stable performance make it one of the popular choices in the electronic industry.
