Fixed inductors are important components of most electrical circuits. The HM66-70820LFTR13 is a fixed inductor built with a copper wire of 15 μm and an air core. It has a rated inductance of 0.018 µH and a rated current of 0.068 A, and it has an operating temperature range from –40°C to +126°C.

In an electronic circuit, the HM66-70820LFTR13 can serve as a filter, allowing only certain frequencies to pass through the circuit. As an inductor, the HM66-70820LFTR13 can store energy in the form of a magnetic field when part of a circuit is charged. When energy is applied, the stored energy is released, increasing the electrical current of the circuit. The HM66-70820LFTR13’s air core helps prevent distortion of the inductor’s magnetic field which can occur when a ferromagnetic core is used.

This fixed inductor is commonly used in applications such as power supplies, DC/DC converters, switching mode power supplies, and induction heating. In a power supply, they are used to condition the power by reducing electromagnetic interference. They also protect and filter out signals generated by the power supply itself. In a DC/DC converter, the inductor helps regulate the current and also serve as a filter. In a switching mode power supply, the inductor is used to store energy for use in high-frequency switching, allowing for higher efficiency.

In induction heating, the inductor acts like a current transformer, allowing for high power inputs to be converted into lower temperature outputs, making it suitable for heating certain materials. In this application, the inductor is used to regulate the amount of current applied, and it also acts like a filter to pulses generated by the induction process.

The HM66-70820LFTR13 has a dual-layer construction. The first layer is an electroplated epoxy resin, which is used to give the inductor a high insulation resistance and to prevent the corrosion of the copper wire. The second layer is a ferrite core, which helps increase the inductance of the device, resulting in a higher current rating.

The operation of the HM66-70820LFTR13 is simple and it does not require any adjusting or calibration. It is important that users observe the inductor’s maximum ratings when using it, as exceeding them could cause serious damage. The HM66-70820LFTR13 is also not suitable for applications that require high reliability or where the inductor must remain consistent over a long period of time.

The HM66-70820LFTR13 is a versatile fixed inductor, suitable for a wide range of applications. With its copper wire and air core construction, it can provide high inductance and reliable operation in a variety of situations, from power supplies to induction heating. To ensure optimal performance, users should observe the inductor’s maximum ratings and not use it in high reliability applications.
