Fixed Inductors Inductors are components that cause a phase shift in current when electrical energy passes through them, and are used in various industries. Fixed inductors, such as the RL1011-151-R, are used when a constant inductance must be maintained over time. The RL1011-151-R is a high-frequency, high-current, ferrite-core, power Inductor used for a variety of applications.Application FieldsThe RL1011-151-R is a common choice in power supply design, as its low DCR and high current handling capability make it well-suited to be a current supplier. The RL1011-151-R’s low profile form also makes it possible to use in various designs, like buck or boost topology switching power supplies. Its excellent resistance to saturation ensures its performance in any topology in which the current varies significantly during the switching. The electrical characteristics of the RL1011-151-R also make it an ideal component for DC-DC converters and for other applications involving high-frequency switching power supplies.Apart from its widespread use in power supplies, the RL1011-151-R finds its application in industrial projects where it is used in voltage regulator modules. It also finds its application in some consumer markets, such as televisions, mobile phones, laptops, and so on. Also, due to its small form-factor, it is possible to integrate the inductor into current and voltage sensors for automotive applications. Working PrincipleThe RL1011-151-R is designed to offer superior performance while still being affordable. It consists of a ferrite core wound with many turns of copper wire. When the current passes through the coil, a magnetic field is generated around the inductor. This field captures the energy of the current and stores it in the form of magnetic energy. This stored energy can then be released when the current ceases, causing a phase shift in current. The RL1011-151-R is designed such that it is insensitive to AC and DC fields and has low energy losses over its broad operating temperature range of -40°C to +125°C. It also offers low DCR and can carry a high current, and these features make it suitable for use in high-frequency power supplies. It is also available in various sizes and shapes, making it even more versatile.In summary, the RL1011-151-R is a high-frequency, high-current, ferrite-core, power Inductor used for a variety of applications, including power supplies, voltage regulator modules, current and voltage sensors, and consumer electronics. Its superior performance and low energy losses make it a great choice in many designs, and its versatility makes it suitable for a wide range of applications.
