<h2>Fixed Inductors</h2><p>Fixed inductors are components that rely on inductance, a property of an electric current that induces an electric field. Inductors are used in a variety of applications, such as for radio frequency transmission, power supply filters and filtering out interference in sensitive circuits. 103-273FS is an example type of fixed inductor.</p><h3>103-273FS Application Field</h3><p>103-273FS is a fixed inductor designed for energy-saving applications. It is mainly used in electronic appliances such as LED bulbs, mobile phones and computers. 103-273FS is a ceramic core inductor that is ideal for high-frequency, low-loss applications.</p><p>It offers high current handling capability and high inductance stability, making it suitable for a wide range of applications. It can be used in converters for portable devices, embedded systems, flyback converters, and mobile device power supplies. It is also suitable for core inductances and resonant circuits.</p><h3>103-273FS Working Principle</h3><p>Fixed inductors, such as 103-273FS, rely on magnetic inductance to convert current into a magnetic field and then store the energy as a magnetic field. The current is generated by an induced voltage and is proportional to the rate of change of the magnetic field.</p><p>When the current passes through the coil, a magnetic field is generated. This magnetic field is proportional to the current. The changing magnetic field induces an EMF in the coil, creating an additional current. This additional current is known as the "back EMF", which reduces the current flowing through the inductor.</p><p>The back EMF increases with frequency, causing energy to move between the magnetic field and the inductor. This process is called resonance. By tuning the inductors\' inductance and reactance, the resonance between inductors and capacitors can be maximized.</p><p>103-273FS also provides an accurate attenuation ratio and is suitable for high frequency, low loss applications thus saving energy. It has low thermal resistance and is designed for a wide range of temperatures, making it suitable for a variety of applications, especially those requiring high-frequency and low-loss performance.</p><p>In short, 103-273FS is a fixed inductor designed for energy-saving applications that rely on inductance. It is suitable for high frequency, low-loss applications and provides an accurately attenuated ratio.</p>
