Fixed inductors, also known as chokes, coils, or reactors, are types of electronic components that store energy in the form of an electrical current when charged through a conductor. SP1812R-153H is a fixed inductor manufactured by Coilcraft, Inc. that is designed for a variety of applications such as power supplies, medical diagnostics, and telecommunications. The device is also suitable for use in harsh environment applications caused by extreme temperatures or vibration. The SP1812R-153H is constructed with a UL 94V-0 rated jacket and features a +105°C temperature rating, making it suitable for high-temperature applications.

The SP1812R-153H fixed inductor consists of a ferrite core and a molded plastic core that is wrapped with an electroplated tin multi-stranded copper wire. The core provides stability and uniform magnetic characteristics, while the copper wire provides low electrical resistance and improved electrical properties. The combination of the two materials creates a durable and reliable fixed inductor that is capable of handling up to 1.5A rms and 15A peak currents, making it suitable for a wide range of applications.

The SP1812R-153H fixed inductor has a wide range of applications. It is commonly used in switching power supplies, as well as high-frequency switching applications such as telecommunications products, medical equipment, and automotive electronics. The device is also suitable for providing voltage regulation in various types of regulated power supplies, replacing electrolytic capacitors for signal filtering and coupling, and providing high-frequency noise suppression as necessary. The SP1812R-153H can even be used in high-voltage applications as it has a high-temperature insulation rating of +105°C.

The SP1812R-153H fixed inductor works on the principle of magnetism. When current flow is applied to the inductor, it stores energy in the form of a magnetic field. When the current flows through the inductor, the magnetic field created induces a voltage in the device, allowing energy to be stored and voltage to be regulated. This device can also be used for pulse applications, whereby the amount of energy stored is determined by the width and amplitude of the pulse.

The SP1812R-153H fixed inductor provides a reliable and efficient solution to many applications requiring energy storage and voltage regulation. The device has a wide range of operating temperatures and voltage ratings, making it suitable for a variety of applications. The device is also fairly easy to install and use, making it a popular choice for many engineers.
