Fixed Inductors

An inductor, also called a coil, choke or reactor, is an electrical component consisting of a length of wire and/or a core of magnetic material that stores energy by producing a magnetic field when an electrical current passes through it. While inductors generally operate under DC current, they are also used in conjunction with AC currents and, while most fixed inductors store energy, variable inductors are also common for use as controlled voltage sources. One example of a fixed inductor is an 80301C, a part manufactured by TDK.

Built on an organic substrate, 80301C uses a low-resistance copper conductor for its coil. The conductor uses a unique vacuum-sintered process which makes it ultra-low resistance and it is made in nine different sizes to accommodate a number of LED and lamp applications, ranging from 0.15 to 1.10 mm«s thick. The outer shell, made of black rosin-based resin, acts as a moisture barrier, while its air gap technology ensures a low DC resistance. The internal coils are also treated with silcoxide to further protect them against moisture.

An 80301C fixed inductor is ideal for use in lighting applications as a weatherproof LED dimmer, LED drivers, and fluorescent lighting ballasts. Its low resistance allows for high power conduction and it has excellent thermal and moisture resistance, allowing it to be used in outdoor applications. In addition, it offers noise reduction due to its low internal resistance, making it an ideal choice for noise-sensitive applications. Its high-temperature operation, low current fluctuation, and superior inductance stability make it a top choice for fixed inductors.

When it comes to the 80301C’s working principle, it works as a basic inductor, with a coupling of the magnetic fields around the coil and magnetic material producing an electrical resistance. This resistance is termed inductance, and is measured by the device\'s self-inductance. When alternating current passes through the coil, the resulting electromagnetic field produces a changing current in the coil, which in turn produces a voltage across the inductance, forming an electrical alternating current. In this way, the coil is able to generate an alternating voltage, which is then used in the circuit.

In summary, the TDK 80301C fixed inductor is an ideal choice for LED drivers, fluorescent lighting ballasts, and other high-current applications. Its low internal resistance makes it ideal for noise reduction and its unique construction ensures improved heat dissipation and weatherproofing. In addition, it has a superior inductance stability, high temperature operation, and low current fluctuation, making it a top choice for fixed inductors.
