Fixed Inductors are types of electrical components known as coils, which are used as factory-preferred parts in electrical circuits and provide good electrical characteristics for increased performance. The S1812-332F is one of the most commonly used Fixed Inductors due to its wide range of operation and ability to perform in difficult operating conditions.

The S1812-332F is a surface-mount component that contains two pins and is designed to fit into small devices. When configured and used in either low-profile package or a medium-profile package, this part provides a relatively high efficiency, as well as a low typical profile of inductance. Additionally, the S1812-332F provides excellent temperature cycling performance that enables it to perform in a wide range of temperatures.

The primary application of the S1812-332F Fixed Inductors is in radio frequency filters due to its low reactive power loss and excellent stability. The use of radio frequency filters reduces the number of spurious signals within the bandwidth of a radio frequency device and improves the efficiency of the overall system. The S1812-332F can also be found in cellular base station filters, satellite navigation modules, and wireless communication systems, contributing to improved system performance and providing increased system bandwidth.

The S1812-332F Fixed Inductors operate in the range of 1.8 to 20 MHz according to their resolution. The inductor’s working principle is based on Faraday’s law of induction, where the magnitude of the induced current is proportional to the rate of change of the magnetic flux. Additionally, the device’s tolerance means the inductance value (given in nanohenries) will remain within the specified range when exposed to standard external variables, including temperature.

The S1812-332F features a highly efficient waveform topology for use in radio frequency applications. This allows for reduced power loss and improved temperature stability, allowing the inductor to maintain its performance specifications regardless of temperature variations. In addition, the S1812-332F features a wide operating temperature range that enables it to be used in extreme environments and to withstand harsh operating conditions.

The S1812-332F Fixed Inductor is a versatile and widely used component in radio frequency filters and various other applications due to its exceptional operational characteristics. Its low power loss, wide operating range, and excellent temperature stability make it a preferred component in radio frequency systems with challenging operating conditions. This component helps to reduce spurious signals and improve overall system efficiency, making it a reliable and valuable part of modern electronics.
