<p>Fixed inductors play a vital role in electronics and electrical engineering. An example of a fixed inductor is the ELL-4LM180M. The ELL-4LM180M stands for the Electrolytic Line and Lead miniaturized Power Bead Inductor.</p><p>This specific inductor is commonly used for its low DC resistance which is beneficial in high power supply applications. Due to its low DC resistance, the ELL-4LM180M is often used for DC-DC converters, high switching power supplies, and DC-AC inverters.</p><p>Its construction consists of a ceramic core, 26 AWG enamel wire wrapped around it and a plastic bobbin. The ceramic core is responsible for providing consistent electrical properties across the entire inductor and the plastic bobbin helps keep the windings together and prevents them from turning into a tangled mess.</p><p>The size of the ELL-4LM180M is also quite small making it an ideal choice for applications where space is limited. Despite its small size, its operating frequency range is quite wide. It has a wide frequency range of 3Hz to 1MHz.</p><p>The working principle of a fixed inductor and the ELL-4LM180M specifically is quite simple. It uses the principle of inductance and magnetic flux to store electrical energy. When a current is applied to the inductor, a magnetic field is created. This magnetic field then creates an opposing voltage which in turn creates an energy which opposes the change in current.</p><p>The more current that is applied to the inductor, the larger the magnetic field and the greater the opposing voltage. This is why the ELL-4LM180M is beneficial for its low DC resistance. It can produce more current with less electrical resistance, making it an ideal choice for high power applications.</p><p>In addition to its high power and low DC resistance, the ELL-4LM180M also offers the benefit of high temperature performance. This makes it suitable for use in very high temperatures which occur in many power electronics applications such as switching power supplies and motors.</p><p>In conclusion, the ELL-4LM180M is a fixed inductor which is commonly used in a variety of high power applications due to its low DC resistance and wide frequency range. It offers a high temperature performance and is ideal for applications where space is limited. It uses the principle of inductance and magnetic flux to store electrical energy and provide a high current output with less electrical resistance.</p>
