Fixed inductors are essential components within virtually every electrical and electronic circuit. They are used in a wide range of applications such as oscillation, filtering, and tuning circuits. The 1945R-17G is a fixed inductor that has seen increasing popularity in recent years for its dependability, reliability and favorable price.The 1945R-17G is a ferrite core inductor with an inductance value of 4.30 mH. It has an operating temperature range of -40°C to +85°C making it suitable for harsh industrial environments and applications in which high temperatures may be encountered. The 1945R-17G is designed with high temperature soldering capabilities which makes it a suitable candidate for automated assembly lines.The 1945R-17G is an excellent choice for AC/DC switching power supply circuits. It is often used in buck converters and other power supplies in order to help reduce ripple at the output stage. This helps to improve the efficiency of the power supply and also reduces electrical noise and interference. Additionally, the 1945R-17G can be used in combination with other inductors to create low pass filter circuits with desired cut off frequency values.The 1945R-17G also excels in high voltage applications due to its breakdown voltage rating of 19.7kV. This allows it to be used in circuits in which high voltage spikes may be encountered. It also has good dielectric strength with a insulation resistance rating greater than 10 MΩ per UL60745-1 and greater than 50 MΩ per EN60745-1.The working principle of the 1945R-17G is based on Faraday’s Law of Electromagnetic Induction. When a loop of wire is exposed to a changing magnetic field, an EMF is created in the wire which is we refer to as inductance. Essentially, a changing magnetic field will induce a voltage in the inductor’s windings which will cause current to flow through the components in the circuit. This then allows for the electrons to move through the inductors coil and create a magnetic field that opposing the original change in the magnetic field. This then helps to regulate and control the flow of current and voltage throughout the circuit.
