Fixed inductors, sometimes referred to as choke coils, are electric components commonly used in the field of power electronics and radio frequency engineering. They are typically used for filtering or coupling purposes. The HM66-705R0LFTR13 is a fixed inductor manufactured by TDK, and is well-suited to use in power supplies and mobile and consumer applications. In this article, the application field and working principle of the HM66-705R0LFTR13 will be discussed.

1. Application Field

The HM66-705R0LFTR13 is a High Current Inductor designed for use in circuit boards. This fixed inductor is available in tape-and-reel packaging for automation process purposes. Due to their high current density, high inductance, low resistance, and high operating temperature, they are well-suited for use in power supplies, consumer electronics, LED lighting, and motor drives.

It is designed to operate in harsh environments – such as high/low temperature and vibration – and is capable of providing stable performance over a wide range of frequencies. Its Kevlar core provides superior vibration resistance and its shielded construction helps reduce emitted radiation. This makes the HM66-705R0LFTR13 a great choice for use in applications requiring minimal EMI emissions.

2. Working Principle

The HM66-705R0LFTR13 is a fixed inductor that uses a cylindrical-shaped ferrite core to store magnetic energy. This is then released to achieve the desired effect. The current that passes through the inductor, however, is characterised by a retarded phase. This means that the amount of time it takes for the current to reach its maximum peak value is greater than the time for the voltage to reach its maximum peak value. This phenomenon is known as phase lag – the lag between the current wave and the applied voltage.

When used with capacitors, the combination of an inductor and capacitor forms a resonant circuit – also known as an LC circuit. In this type of circuit, the inductor and capacitor interact with each other to produce a resonant frequency. This frequency is determined by the values of inductance (L) and capacitance (C) used in the circuit. By adjusting these two values, the frequency of the circuit can be tuned to produce desired results.

The HM66-705R0LFTR13 is capable of providing stable inductance over a wide range of frequencies. With its shielded construction, this fixed inductor is also capable of reducing emitted radiation, making it well-suited for use in applications that require minimal EMI emissions.
