Introduction to Fixed InductorsFixed inductors, also known as ceramic high frequency inductors, are passive electronic components mostly made up of ceramic and ferrite materials. These components are ideal for high-frequency applications such as power supplies, radio receivers, and oscillators as they are able to handle high power levels and frequencies in an appropriate manner. The core material of fixed inductors is usually a ferrite material and an insulated copper wire is coiled around it.Fixed inductors offer several advantages and benefits. They are quite small and lightweight in comparison to air-core inductors and also come at a much lower cost. In addition, they have a high inductance to size ratio which makes them suitable for use in small and confined spaces. Finally, these components are quite stable even after undergoing a significant amount of heat.LK10052R2K-T Application Field and Working PrincipleThe LK10052R2K-T is an example of a fixed inductor.
