Fixed inductors are electronic components whose inductivity value remained constant even when the current or voltage in the circuit changes. This type of inductor is composed by winding of wire onto a form, when current pass through the inductor coil, an oppositive resistive force is generated, this is called back electromotive force. The fixed inductor is very versatile and can be used in different types of electronic applications where signal filtering and sensing are required.

The 1812R-183J series of fixed inductors is a popular choice for electronic projects particularly in the fields of aerospace and defence. These devices feature a high manufacturing quality and are able to deliver reliable performance in a wide range of dangerous and hostile environments. They have been designed to easily fit amongst and blend into existing equipment and do not require extensive maintenance.

The 1812R-183J\'s inductance value is relatively low, ranging from 1.8uH to 180uH, with a current range of from 0.6-6.0A. The package size of the inductor are also small, ranging from 1.2x1.8mm to 18.0x18.0mm. This small size is advantageous for applications where space is limited.

The typical working principle of 1812R-183J fixed inductors is operating based on magnetic field. When the current reaches the inductor, copper coil will generate a magnetic field and an electric field. When current encounters a resistance, heat will be generated; when the current encounters an inductor at first, the magnetic field generated by the inductor will oppose the current, thereby slowing the current down.

The 1812R-183J is ideal for circuits which require impedance level control and accurate inductance for signal control such as in analog-to-digital converters, power supply-based sensing systems, rfic protection circuits, load switch protection circuits and more. It can also be used in analogue filter circuits such as low-pass filters and tracking filters for efficient signal control.

The 1812R-183J fixed inductors can supply a stable resistance value, good linearity and high saturation. They offer excellent surge current capabilities and are able to withstand high ripple currents of up to 4A. Furthermore, they have a quick heat dissipation rate and temperature stability, providing a much better performance in applications with high temperature environments. The inserted component is made up of high temperature alloy and therefore can operate at temperatures up to 1550°C.

In conclusion, the 1812R-183J fixed inductors are an ideal choice for demanding applications such as aerospace and defence, as they offer excellent performance in a variety of environments and can help to reduce the overall circuit size. Furthermore, their efficient magnetic field, accurate inductance, superior surge current capabilities and quick heat dissipation rate are additional features which make them suitable for an array of applications.
