Fixed InductorsFixed inductors are electrical components which consist of an inductor and a core that is itself made of an electrode, a dielectric layer, and an additional metallic coating, often referred to as a winding. They are used to store energy in a magnetic field and are often used in high-frequency circuits, as they allow for much higher current densities than many other types of inductors.The 1945R-16F is a fixed inductor which is widely used in audio-frequency and radio-frequency (RF) circuits. It is designed for use in the 15MHz to 200MHz frequency range, making it ideal for those applications that call for very high frequency operation. The 1945R-16F is a type of high-frequency inductor which is used in several design applications, such as low pass filter circuits, broadband matching, and impedance matching.The 1945R-16F consists of a ceramic core surrounded by a winding made of metallic wire. This winding is connected to two external terminals, which are usually referred to as the anode and the cathode. When a voltage is applied to the 1945R-16F, the current in the winding creates a magnetic field, which induces a voltage in the windings of the 1945R-16F. This effect is known as self inductance.The 1945R-16F is a relatively low power inductor, and its application field is mainly limited to low power electronics. However, the self inductance effect produced by the 1945R-16F can be used in several applications, such as power supplies, voltage regulators, and motor controllers. In power supplies, the inductor is used to maintain a constant output voltage. In voltage regulators and motor controllers, the 1945R-16F is used to create a stabilized output, reducing the voltage drop across the inductor.The 1945R-16F also has some advantages over other types of inductors. For instance, the 1945R-16F is a relatively low cost inductor, and it has a relatively high self inductance, which makes it ideal for high-frequency circuits. Furthermore, the 1945R-16F is also relatively small in size, making it easier to fit in space-constrained applications.In conclusion, the 1945R-16F fixed inductor is a widely used component in high-frequency electronic circuits, as it exhibits excellent self inductance properties and is relatively small in size and low in price. Its application field extends to low power electronics, power supplies, voltage regulators, and motor controllers.
