Fixed inductors play an important role in electronic circuits. They are used to store energy in magnetic fields and control the flow of current. In this article, we will take a look at the application field and working principle of the 0925R-821J, a fixed inductor manufactured by Ebrah Electronics.

Application Fields

The 0925R-821J is a precision fixed inductor with a maximum inductance of 90 µH and tolerances up to ±5%. This makes it suitable for applications such as radio frequencies (RF), local area networks (LAN), and wireless sensor networks (WSNs). Its wide frequency range (20KHz~1MHz) and low insertion loss enable it to be used in high-bandwidth and signal-sensitive circuits. The 0925R-821J also has high temperature and humidity tolerance, making it suitable for applications that require reliable and stable performance in harsh environments. It is commonly used in power supplies, audio amplifiers, medical equipment, and telecommunication devices.

Working Principle

Fixed inductors are electronic components that store energy in a magnetic field. They consist of a coil of wire surrounded by a core material. When current passes through the coil, it creates an electromagnetic field that is then stored in the core. This stored energy can later be released as an opposing current when the current is removed.

The 0925R-821J has a core material made of a permalloy that gives it greater storage capacity and higher stability compared to other inductors. The permalloy core helps to reduce electrical noise and dissipate heat quickly, thus ensuring reliable performance in high-power circuits. Its self-shielding design also helps to reduce the adverse effects of external interference.

The 0925R-821J uses a split core construction that allows it to be easily mounted and provides access to the inductance adjustment screw. Depending on the needed inductance, the user can adjust the amount of turns in the coil. This allows precise tuning and ensures that the inductor works in the expected frequency range and that it meets the required specifications.

In conclusion, the 0925R-821J is a precision fixed inductor that is suitable for applications such as radio frequencies (RF), local area networks (LAN), and wireless sensor networks (WSNs). It has a wide frequency range (20KHz~1MHz) and can withstand harsh environmental conditions due to its permalloy core. It also has a split core construction that allows it to be easily mounted and provides access to the inductance adjustment screw. This inductor is an ideal choice for circuits that require reliable and precise performance.
