Our fixed value inductors have a very wide range of inductance values - from 2.2µH to 10H.A fixed inductor or fixed coil will always have the same inductance. Inductive reactance increases with frequency, unlike capacitive reactance which reduces. Types of fixed inductors include air-core, iron-core, and ferrite core, with single-layer or multiple-layer coils. Fixed inductors tend to be more compact and more convenient than variable inductors, making them an excellent choice for applications in which steady inductance is desired. Fixed inductor advantages include small size, light weight, stable structure, and convenient use and installation.Inductors have shielding cases to prevent any generated magnetic field from affecting the operation of nearby circuits and components. After the inductors are wound, the coils and magnetic cores are packaged with plastic or epoxy resin.What are fixed value inductors used for?Inductors are used in many different applications, primarily analogue circuits and signal processing. Very large inductors can be paired with filter capacitors to remove ripple from power supplies, while very small inductors can prevent radio frequency interference. In switched-mode power supplies, inductors may be used as energy storage devices for DC current, keeping current flowing when the switch is “off” and allowing the output voltage to exceed the input voltage.An inductor connected to a capacitor creates a tuned circuit that serves as a resonator for oscillating current. These are often used in radio transmitters and receivers, as well as in electronic oscillators. A transformer consists of two inductors with mutual inductance. Transformers are an important part of any power grid.
