Fixed InductorsFixed inductors are electrical components that are used to induce an electric current in a circuit, and are usually employed when a specific amount of inductance is needed. Fixed inductors are typically used as filters, in oscillators, and in various other types of sensitive electronic circuits. ER1537-26KM is one type of fixed inductors with vast uses.ER1537-26KM is a mini molded power inductor, designed for low-loss and high-frequency applications such as DC-DC converter, switching regulator, inverter, PFC, etc. It comes in a small axial package with an enclosed core, allowing for higher power densities. The small axial package also offers significant space savings. The inductance category of the ER1537-26KM ranges from 0.2uH to 22uH, and its maximum DC current is 15.4A.ER1537-26KM is specifically designed for operation in high frequency power circuits up to 250MHz, and is able to operate at temperatures up to 125°C. The inductor is built using a special ferrite material, ensuring stability of the coil’s characteristics over temperature and frequency, and minimizing noise.The ER1537-26KM also have excellent heat resistance, moisture resistance, and environmental stress resistance.The working principle behind ER1537-26KM is based on the core magnetic field of the coil, which is generated when a current flows through the coil. This magnetic field is generated between the turns of the coil, inducing an electromotive force in the opposite direction of the current. This electromotive force is known as inductance, and can be used to reduce or filter signals or act as a source of voltage in oscillator circuits.There are various applications that use ER1537-26KM inductors, including DC-DC converters, switching regulators, inverters, PFC, and noise filters. DC-DC converters use the inductor to store energy during step-up and step-down processes. Switching regulators and inverters use the inductors to improve the voltage or current control. This results in more efficient power systems. PFC circuits also use the inductors in order to reduce power supply noise and improve voltage stability.Similarly, in noise filter applications, the inductors are used to reduce inadvertent noise entering the system. When integrated on to PCBs, the inductors can significantly reduce unwanted emissions from interfering with other components in the circuit. The inductors help reduce electrical noise from the high frequency applications by offering high impedances at targeted frequencies.ER1537-26KM are used for various high frequency power applications, and the vast advantages of these inductors allow for more efficient operation and systems. The wide working operation temperature, high power and current densities, and high frequency response makes the ER1537-26KM one of the most versatile power inductors today.
