LHL10TB471K Inductors, Coils, Chokes

Fixed inductors are electronic components specifically designed to provide a constant signal with minimal fluctuation. The LHL10TB471K is a fixed inductor that is used for power electronics applications, and part of the Thorlabs OEM lineup. This inductor was specifically designed for advanced power electronics applications, enabling it to handle large inputs of current and power.

The LHL10TB471K is part of the Thorlabs OEM inductor series. It consists of a 10μH inductor with a 1A current and 600mOhm DC resistance. The product consists of a full-metal body that is capable of dissipating heat efficiently and withstanding vibrations. Additionally, it has a wide operating temperature range, from -40 to +85°C.

The major application fields of the LHL10TB471K are power and data transmission lines. They can be used as filters, in DC-DC converters, and as inductors in power supplies. It can also be used as a replacement for Ni-Zn ferrite and inductor arrangements. Because of the low DC resistance, it is also suitable for use as a surge limiter, to suppress overvoltages.

The working principle of LHL10TB471K is based on Faraday\'s Law. When current flows through a coil, it produces a magnetic field around the coil. This magnetic field then induces a voltage in the coil that is proportional to the rate of change of the current. This voltage, also known as the back-emf, is opposed to the applied voltage, resulting in a decrease of power dissipated in the inductor.

In addition to Faraday’s Law, the LHL10TB471K also makes use of self-resonance. This is a phenomenon where an inductor loses its inductance after the frequency of the applied signal is higher than the inductors self-resonant frequency. The LHL10TB471K is able to counteract this by using an advanced magnetic core that can effectively convert household electric signals to a higher frequency, thus avoiding any losses in power.

The LHL10TB471K is an excellent choice for power and data transmission applications. Its low DC resistance, wide operating temperature range, and ability to dissipate heat efficiently make it a valuable component for these types of applications. In addition, the self-resonance technology ensures that power is not lost even when dealing with high frequencies, further increasing the value of the component.
