Fixed inductors are passive components that store energy in the magnetic field created by electric current. They are used in a variety of electronic devices and are especially useful in applications where other passive components may not be suitable, such as filters and resonators. The RL110-391K is a type of fixed inductor that is widely used in applications such as radio frequency (RF) and cellular communication systems. In this article, we will discuss the application field and working principle of the RL110-391K.

The RL110-391K is a type of air core inductor with a total inductance range of 11 to 391 nH. This makes it an ideal choice for applications where precise control of parameter values is required. For example, it can be used in a variety of RF and cellular communication systems, such as mobile phones, GPS navigation systems, and satellite communication systems. Additionally, it is also used in some automotive applications, such as airbags and power windows.

The RL110-391K is a multi-turn inductor with a ceramic core. The core provides the inductor with stability, while also reducing eddy currents. The inductor also features an enclosed metal shield that helps protect the inductor from EMI and RFI interference. Additionally, the shield also helps reduce losses due to magnetic field radiation.

The working principle of the RL110-391K is based on Faraday’s law of induction. When electric current is passed through an inductor, a magnetic field is created. When this magnetic field changes, it induces an opposing electric current. This opposing electric current is what generates the inductor\'s total inductance. In the case of the RL110-391K, the source current generates an opposing voltage which is what creates the total inductance.

The RL110-391K is designed to operate optimally at frequencies between 100 kHz and 2 MHz. At higher frequencies, the inductor\'s efficiency begins to drop, and at frequencies above 2 MHz, the inductor may not be suitable for use. Additionally, the RL110-391K has an effective series resistance of 0.6 Ω to 2.2 Ω, meaning that it does not cause excessive power loss when operating at the specified frequencies. Furthermore, its tolerance range is between -5% and +30%. This means that the inductor behaves according to the values stated by the manufacturer.

In conclusion, the RL110-391K is a type of fixed inductor that is used in a variety of RF and cellular communication systems. It features a ceramic core and an enclosed metal shield that helps reduce losses due to magnetic field radiation. Its working principle is based on Faraday’s law of induction, and it operates optimally at frequencies between 100 kHz and 2 MHz with an effective series resistance of 0.6 Ω to 2.2 Ω, and a tolerance range of -5% to +30%.
