Fixed inductors are components that store electrical energy in the form of magnetic fields. The 1782R-37F is an example of a fixed inductor. It is designed to meet MIL-PRF 21064 condition, Class 1, Type FF, reide rank C performance. It has an ultra-low profile of 0.37" (9.4 mm), and a very wide operating temperature range from -55°C to +125°C. This model also features a high inductance to volume ratio and a tight tolerance of ±5%.

The 1782R-37F fixed inductor is mostly used for RF, microwave and mobile communications applications. Its ability to pass high frequencies allows it to be used in antenna matching, tunable RF filter circuits, signal transmitting and receiving circuits, as well as voltage regulators.

The working principle of a fixed inductor involves the magnetization of a metal core by a current passing through a coil. When a coil carrying an electric current is placed within a metal core, a strong magnetic field is generated that induces a voltage back to the coil. The magnetizing force, current, and coils create the inductance, which is a measure of the amount of energy stored in the inductor.

This stored energy is then returned to the circuit when the current reverses its direction. This phenomenon is called “inductive reactance”. It is an opposition to the flow of current which is proportional to the inductance of the inductor. The higher the inductance of the inductor, the more current is required to produce the same voltage.

In addition, the self-resonant frequency is also a critical parameter. This is the frequency at which the inductor’s impedance is equal to its resistance, resulting in complete cancellation of the inductive reactance and maximum voltage across it. The 1782R-37F has a self-resonant frequency of 4.5GHz, making it suitable for most applications.

Overall, the 1782R-37F is a high quality fixed inductor with a wide range of features and benefits. Its small size, high inductance, and wide operating temperature range make it an ideal solution for a variety of RF, microwave and mobile communication applications. Its tight tolerance and self-resonant frequency ensure reliable operation and excellent performance. It is no wonder why the 1782R-37F is such a popular and widely used component.
