Fixed Inductors: MIL1812R-684J

Fixed Inductors, such as the MIL1812R-684J, are extensively used in radio and television receivers, audio amplifiers, computers, communication equipment, and countless other applications. They are invaluable components that perform the valuable function of storing electrical energy. Let\'s explore the background, application field, and working principle of this device.

Background

Fixed Inductors have been around since the late 19th century when the invention of electricity redefined human civilization. The device was first used in the telephone for the purpose of signal processing and AC/DC coupling. From there, the concept of energy-storing components quickly filtered into other applications. As the years progressed, the use of fixed inductors grew exponentially and today they’re found in virtually every piece of electronic equipment.

Application Field

The MIL1812R-684J Inductor is a Fixed Inductor specifically designed for high-frequency applications. This device offers high stability and reliable performance. It is often used in antenna systems, base stations, CATV equipment, frequency synthesizers, and other radio systems. Additionally, this inductor is suitable for use in image and signal processing.

Function & Working Principle

The basic working principle of a Fixed Inductor is simple. Whenever an alternating current (AC) runs through it, a magnetic field is created. The energy from the current is stored temporarily in this field and that\'s how the inductor is able to store electrical energy. The MIL1812R-684J is designed to allow for a maximum current of up to 18A and can handle a frequency of up to 600 MHz. It operates at an impedance range of 33 to 44 ohms and has an inductance value of 0.68uH.

Conclusion

Fixed inductors are invaluable components that store electrical energy for use in radio and television receivers, audio amplifiers, computers, communication systems, and countless other applications. The MIL1812R-684J is a high-performance device that offers reliability and performance that is in line with the latest industry standards. Its robust design ensures that it can handle voltages up to 18A at a maximum frequency of 600MHz.
