Fixed Inductors encompass a wide range of inductor types. They are usually composed of coils of wire wrapped around an iron core, some kinds may not have a core at all. Depending on the type of inductor, they can possess some unique characteristics based on their design and construction. The 1140-103K-RC is one such inductor, and this article will detail its application field and working principle.The 1140-103K-RC is a type of surface mount inductor that is used predominantly in antenna matching circuits or for filter matching. It is an off-the-shelf product that is fabricated specifically for a variety of RF (Radio Frequency) applications. It is small in size and designed for easy placement on a printed circuit board (PCB) without the need for any additional soldering steps. The inductor is capable of handling signals up to 5 watts, making it suitable for use in circuits that require a high frequency response.The primary purpose of the 1140-103K-RC is the reduction or elimination of unwanted signals. It performs this feat through the production of an inductance, or opposition to change in current, when a signal of any frequency is applied. The inductor captures the signal and passes it through a circuit arrangement composed of a resistor and a capacitor. This arrangement is known as an L-C or inductor-capacitor circuit. This type of circuit allows the inductor to serve as a filter by eliminating frequencies that are outside the range of desired signals.When a signal is applied to an 1140-103K-RC inductor, the resistor and capacitor act as a resistive load, making it difficult for the current to flow. This forces most of the signal, including undesirable frequencies, to be reflected back towards the source. The frequencies that are allowed to pass through the circuit arrangement are those that are within the range of the desired signal, such as WiFi or Bluetooth.In addition to filtering unwanted signals, the 1140-103K-RC inductor is also able to serve as an antenna matching device. This is accomplished by creating a resonance circuit, which is composed of an inductor and a capacitor working together. This circuit allows the inductor to absorb energy transmitted by the antenna and redirect it into the desired signal at a higher frequency. In this manner, it is capable of amplifying the signal and improving the power output.The 1140-103K-RC inductor is an efficient and cost-effective solution for antenna and filter matching applications. It is compact and simple to install, making it suitable for a wide variety of projects. Its ability to filter frequencies and amplify signals ensures that it can be implemented in any setting requiring a reliable component for low-power, high-frequency applications.
