Fixed inductors are electronic components that store energy in the form of a magnetic field when electricity is applied. The 105R-821K is a specific type of fixed inductor from Murata that is used in a variety of electronic application fields. This article will discuss the 105R-821K application field and working principle.

The 105R-821K is a low profile, compact inductor from Murata. It is especially designed for low-frequency applications in power supplies, inverters, DC-DC converters, and resonant converters. The 105R-821K is available in two sizes, 821KLP05 and 821KLF05. The 821KLP05 is a larger component with a height of 10.8 mm and a diameter of 4.5 mm. The 821KLF05 is a smaller component with a height of 8.2 mm and a diameter of 3.2 mm.

The 105R-821K series has excellent frequency characteristics with low resistance and high Q factors. The inductance range is between 0.100 to 1.2 uH. The rated current is between 0.2A to 1.6A. The maximum DC resistance is 0.47mΩ to 2.5mΩ. The maximum rated current is 1.6 Archermans with the operating temperature ranging from −40°C to +105°C. These characteristics make the 105R-821K series optimal for circuits that require high performance such as Blu-ray players, HDTV receivers and automotive applications.

The basic working principle of the 105R-821K is the same as any other type of fixed inductor. When a current is applied to the inductor, a magnetic field is generated around the component and energy is stored in this magnetic field. This stored energy is released when the current is reduced or removed. Thus, the inductor resists a change in the current, allowing for high precision electrical signals to be passed through it.

In addition to its excellent frequency characteristics, the 105R-821K series also offers excellent reliability. It uses the latest process technologies, and its electrodes are highly resistant to corrosion. This ensures that the 105R-821K has a long life and is reliable under all conditions.

Overall, the 105R-821K series from Murata is a type of fixed inductor that is optimized for low-frequency applications. It offers excellent frequency characteristics with low resistance and high Q factors and is highly reliable thanks to its corrosion-resistant electrodes. As such, the 105R-821K is an ideal choice for Bluetooth and automotive electronics.
