Fixed InductorsFixed inductors, also called chokes or filters, are used in a wide range of applications including power supplies, communication systems, and consumer electronics. They play an important role in stabilizing and filtering electrical circuits by preventing interference and regulating current flow. The 160R-681FS is a type of fixed inductor that is suitable for use in a variety of applications. This article will provide a overview of the 160R-681FS, including its application field and working principle. The 160R-681FS is a non-polarized, molded fixed inductor ideal for decoupling applications. It is made from high-purity, high-frequency materials and has a wide temperature range from -55°C to +135°C. It features an 8.5mOhm DCR and a maximum DC current rating of 1.38A. The inductance value is 6.8uH ± 10%, with a rated tolerance of 5% and a 3kHz-15VSR (self-resonant frequency). The 160R-681FS has a very low parasitic capacitance, making it an ideal choice in high-frequency applications.The primary application of the 160R-681FS is in switching power supplies. Its low-resistance DCR means it can be used as a filtering inductor for decoupling low-voltage inputs such as cell phones, tablets, and other consumer electronics. Its low-profile design is suitable for surface mount applications, while its wide temperature range allows it to be used in high-temperature environments. The 160R-681FS is also suitable for other applications such as DC-DC converters, logic supply systems, and motor inverters.The working principle of the 160R-681FS is based on Faraday’s law of induction, which states that when a current-carrying wire is placed in a magnetic field, it will induce a current in the surrounding circuit. This relationship is expressed mathematically by Faraday’s equation, which states that the magnetic flux is equal to the current times the number of turns in the wire. In the case of a fixed inductor like the 160R-681FS, the current is supplied by the inductor itself, creating a magnetic field around the inductor. When a current-carrying wire is placed in this field, a voltage is induced in the circuit, which in turn can be used to generate power.The 160R-681FS is a versatile fixed inductor with a variety of applications and a robust operating temperature range. Its high-quality, high-frequency materials can withstand the rigors of the most demanding applications, making it an excellent choice for power supplies, communication systems, and consumer electronics. The 160R-681FS is designed to provide smooth filtering performance, great reliability, and high power handling capability, making it an ideal choice for decoupling applications and other high-frequency applications.
