MILS1812R-824K

Fixed Inductors

Fixed inductors are components that are designed to produce a magnetic field when current flows through them. They are used in a wide variety of applications and often serve as the interface between the electrical and mechanical worlds. The MILS1812R-824K is a fixed inductor designed specifically for mounting on a printed circuit board (PCB).

Application

The MILS1812R-824K fixed inductor is designed for use in a wide variety of applications, primarily in the telecommunications and computing industries. This inductor is particularly well-suited for high-radiation environments such as those found in satellite communications systems. Other applications for this inductor include filtering, switching, waveform shaping, and signal conditioning.

Tolerances

The MILS1812R-824K inductor is rated for a maximum current tolerance of 2.3 Amps with an operating temperature range of -40 to 175 degrees Celsius. Its inductance tolerance is +/- 10% at 100 kHz, with an inductance of 900 nH. It also features a resonant frequency range of 11.7 to 12.6 MHz and a temperature coefficient of 1 to 40 ppm/degree Celsius.

Working Principle

The working principle of a fixed inductor, such as the MILS1812R-824K, is relatively simple. When current is applied to the inductor, a magnetic field is produced, which induces an oppositely-directed magnetic flux within an adjacent coil. This flux opposes the original current, causing a voltage in the opposite direction to the current. This voltage is called the back-emf, and it limits the amount of current that is allowed through the inductor.

The magnetic flux is also responsible for inducing a voltage in the opposite direction to the back-emf, which is called the self-inductance voltage. This voltage causes the inductance of the inductor to increase, limiting the current that can flow through it even further. The amount of current that can be allowed through the inductor is determined by the inductance and the applied voltage.

Conclusion

The MILS1812R-824K is a fixed inductor designed for use in a wide variety of applications, particularly in telecommunications and computing systems. Its high-radiation tolerance makes it well-suited for applications in satellite communications systems, while its inductance and voltage ratings make it suitable for filtering, switching, waveform shaping, and signal conditioning. The working principle of the MILS1812R-824K is based on the principles of electromagnetic induction, wherein a magnetic field is produced when current is applied and an oppositely-directed voltage is generated in the coil, limiting the amount of current that can be allowed through the inductor.
