Fixed Inductors, while not as widely-used as their counterparts such as capacitors or resistors, are an important part in a wide range of electronics. They are used in power supplies, signal conditioning, radio transmitters, and more. One such type of fixed inductor is the HM66-301R2LFTR13. This part is designed for use in power supplies and power line filter applications where high stability, high current ratings, and low temperature coefficients are required.The HM66-301R2LFTR13 is a fixed inductor with a lead-free tin over nickel finish. It has a rated inductance of 10 μH ± 10%, rated current of 13A, Self-resonant frequency of greater than 400 MHz, saturation current of 20A, and temperature coefficient of 20 ppm/°C. Additionally, it has a maximum operating temperature of +105°C. The HM66-301R2LFTR13 is suitable for use in high power switching applications, signal conditioning, and power factor correction.The primary working principle behind a fixed inductor is Faraday’s Law of Induction. This law states that when a current flows through a conductor, a magnetic field is generated around the conductor. This magnetic field is constantly changing with the changing currents in the conductor. When this magnetic field interacts with another conductor, a voltage is induced in the other conductor. This induced voltage is dependent upon the amount of the change in the magnetic field. This voltage is also inversely proportional to the inductance of the conductor, meaning that as the inductance increases, the induced voltage decreases.In fixed inductors, this phenomenon is used to maintain a steady resistance which helps reduce noise and interference. Most fixed inductors are designed to limit the amount of current that can pass through them. Since the resistance is constant, the amount of voltage across the inductor is also constant. This helps reduce interference as the inductor is able to provide a steady resistance even under varying current. The HM66-301R2LFTR13 is able to provide a steady resistance across a wide range of temperatures due to its low temperature coefficient. This makes the part suitable for use in high power switching applications as it is able to maintain a steady resistance in high temperature environments. Additionally, the HM66-301R2LFTR13 has a high current rating, making it suitable for use in power line filter applications. Its high self-resonant frequency also makes it suitable for use in signal conditioning applications. In conclusion, the HM66-301R2LFTR13 is a fixed inductor with a lead-free tin over nickel finish. It has a rated inductance of 10 μH± 10%, rated current of 13A, Self-resonant frequency of greater than 400 MHz, saturation current of 20A, and temperature coefficient of 20 ppm/°C. It is suitable for use in high power switching applications, signal conditioning, and power line filter. Its low temperature coefficient, high current rating, and high self-resonant frequency make it suitable for a wide range of applications.
