Fixed InductorsFixed inductors, also known as choke coils, are devices that use inductance to regulate an electrical current. They are used in a wide variety of applications such as signal conditioning, radio frequency (RF) and microwave transmission, and power supply control. The DRA125-3R3-R is a specific type of fixed inductor that has a rated inductance of 125mH and a self-resonance frequency of 3.3GHz.The DRA125-3R3-R is designed and manufactured for use in a variety of applications, including DC/DC converters, electronic ballasts, RF power amplifiers, wireless communication systems, and laptops. This inductor is also suitable for metered applications, as it offers a high-frequency response and stable inductance.The working principle of a fixed inductor is based on electromagnetic induction. When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire. This force is called Faraday\'s Law of Electromagnetic induction, and it states that a changing magnetic flux induces a voltage in a circuit. By placing a winding of wire around a ferromagnetic core, the magnetic flux created by the current is increased, creating a larger induced voltage. This effect is used in DRA125-3R3-R to generate the desired inductance.The construction of the DRA125-3R3-R includes a wirewound element and a ceramic core. The ceramic core is composed of a ferrite material, such as Mn/Zn ferrite. The wirewound element consists of a copper a layered winding that is insulated with polyimide film. The combination of these two elements creates an inductance that is stable over the intended frequency range and produces low power loss.The advantages of the DRA125-3R3-R include increased efficiency, improved signal integrity, and higher power capacity. The higher efficiency is due to the improved core material that reduces the power loss from the inductor. This increases the operating efficiency over the entire application range. The increased signal integrity is due to the reducing cross-adsorption between multiple inductors. This allows for improved system performance and reduces noise levels. The higher power capacity is due to the increased current capacity that is possible with the improved core materials. This allows for higher power to be used in applications where large currents are required.The DRA125-3R3-R is an ideal choice for a wide range of applications in consumer electronics, automotive, and industrial sectors. It is designed to provide a high level of power control and signal integrity, as well as a long operating life. Its compact size and high-quality components make it an ideal choice for those who need a reliable, space-saving power management solution.
