Fixed Inductors

A fixed inductor is an electrical component that has one or more coils that convert electrical energy into magnetic energy. It has a core in which the coil is wound around and a fixed inductance value.

1140-3R3M-RC Application Field and Working Principle

The 1140-3R3M-RC is a steel-cased fixed inductor used for radio applications within communication engineering. It is rated up to 1 MHz maximum with 3.3 μH of inductance and a rated current of 200 mA. The 1140-3R3M-RC has a minimum impedance of 450 Ohms and a DC resistance of 27 Ohms. It is of an open-frame construction with a ferrite core and a steel-encased form factor.

The working principle of the 1140-3R3M-RC is that when an AC current is applied to its coil winding, a magnetic field is generated around it. This creates a circular magnetic field that induces a voltage in the core that opposes the applied voltage. This is known as electromagnetic induction and is the principle behind the operations of all inductors.

The 1140-3R3M-RC is constructed with a ferrite core that acts as a resonator. This resonator stores the energy generated by the magnetic field and enables it to be released in a continuous manner. This helps improve the efficiency of the inductor by reducing the power dissipation from the inductor.

The advantage of the 1140-3R3M-RC is that it works with very low wattage power supply sources and can handle a maximum power dissipation up to 250mW. This makes it suitable for low-power communication engineering applications that do not require high-power levels. Its steel core also makes it resistant to distortion and interference. In addition, its open-frame construction and thin profile make it easy to install and provides space-saving.

The 1140-3R3M-RC fixed inductor is ideal for use in communications engineering applications such as radio frequency circuit designs. Its high inductance and low DC resistance make it well-suited for applications that require precise inductance values and impedance control. Its steel core provides stability and ensures consistent performance over a wide temperature range.

In summary, the 1140-3R3M-RC fixed inductor is an ideal choice for use in radio applications, where precision and high efficiency are desired. Its steel core ensures excellent stability, low power dissipation and distortion, and a thin profile provides for space-saving benefits.
