Fixed Inductors

An inductor, also called a coil, choke, or reactor, is an electrical component consisting of a wire or other conductor wound into spiral or other shapes and often used in electronic circuits to store energy in a magnetic field or to provide electrical impedance matching. Fixed inductors are inductors with a fixed inductance or that are used at a fixed frequency. Fixed inductors are commonly used in RF signal processing, DC-DC converters, and power factor correction applications.One example of a fixed inductor is the SPD74R-273M. This is an SMD plastic package of an shielded power inductor designed to be used in DC-DC switching power converter stages where large current is expected. This specific inductor is exceptionally suited for use in high-speed circuit applications, and features a temperature resistant substrate material and an inductance value range of 1-10 mH, making it ideal for use in noisy and harsh operating environments.The working principle of the SPD74R-273M is based on the concept of magnetic fields. When an alternating current is passed through the the wire coils, a magnetic field is created. This magnetic field then produces an opposition to the flow of current, known as inductance. In addition to the inductance, the SPD74R-273M is suitable for high frequency operation, due to the use of ferrite core material, which reduces the core losses.The SPD74R-273M is designed for use in many different applications, including switching power supplies, regulated power supplies and other power related circuits. It is used in applications in the automotive, industrial, and consumer electronic industries. It is especially suited for power factor correction and voltage converter applications, due to its wide current range and high temperature operation.In addition to its use in power related applications, the SPD74R-273M can also be used in various consumer electronics. This includes video game systems, cell phones, PDAs, and other portable electronic devices. Due to its small size and low power dissipation, the SPD74R-273M can also be used in many other applications where space and power are of a premium. The SPD74R-273M is a great fixed inductor that has a wide range of applications. Its small size and low power dissipation make it ideal for many applications, including power related and consumer electronics. Its magnetic field allows it to provide excellent inductance for higher frequency applications. With its wide current range and broad operating temperature range, the SPD74R-273M is an excellent choice for many applications.
