Fixed inductors are basic passive electrical components to convert electric power from one form to another. They are inherently energy storing devices which act as a filter in electronic circuits and can affect the current flow in a circuit. Fixed inductors are commonly used in applications for AC power, RF power, and signal isolation.The 0819R-38F is a fixed inductor from the 0819 series and is designed for use in high-frequency, high-power applications in the power supply circuits of home appliances, industrial equipment, and computers.It is a non-polarized inductor with an 18.5 microhenry inductance in a shielded construction with a ferrite core. Its effective temperature range is between -10 degrees Celsius and +55 degrees Celsius. The 0819R-38F has very low internal resistance and is designed to minimize magnetic interference.In normal operation, the 0819R-38F functions as an electrical transformer that produces a magnetic field in the core, causing a current to flow in the primary winding and inducing a voltage in the secondary winding. At higher frequencies, the core field can saturate, resulting in a decrease in inductance. It is important to note that the impedance and inductance of the 0819R-38F will vary with the frequency of the signal.The 0819R-38F is typically used in applications as a choke coil, suppressing the common-mode noise in the signal by interfering with the signal transmission and absorbing unwanted vibrations. It can also be used to store magnetic energy, by releasing it in response external signals. In addition, it can function as an EMI filter.The 0819R-38F also has multiple safety features, such as short-circuit protection, temperature overload protection, and voltage overload protection, making it suitable for a variety of applications.As a fixed inductor, the 0819R-38F is designed to work reliably in a wide range of uses, from high-frequency RF power supply circuits to EMI filtering and signal isolation. Its design allows it to efficiently dissipate power, while its high-temperature construction ensures reliable operation in extreme temperatures. Its safety features make it ideal for use in high-power applications in industrial and home appliance circuits.
