Fixed inductors are small devices used in many electronic circuits to store energy in the form of a magnetic field. A common example is a transformer, where the magnetic flux generated by the primary coil induces a voltage in the secondary coil. The fixed inductor is a passive electronic component, designed to maintain a fixed inductance, meaning it resists changes in current when a voltage is applied.

The specific device under discussion, the LQH43CN101K03L, is an SMD molded inductor particularly well suited to high frequency applications. It has an inductance of 10µH ± 10%, which equates to a very low resistance to changes in current when a voltage is applied. It is also a high-current inductor, with a rated current of up to 1.6A.

The LQH43CN101K03L features an encapsulated coil structure and uses high-intensity ferrite rods as its core material to improve magnetic flux density. With its molded case, it provides excellent insulation, protection against shock, vibration and EMI (Electromagnetic Interference). This makes it the perfect choice for a variety of high-frequency applications.

The LQH43CN101K03L is typically used in circuits where a wide range of frequencies need to be handled, such as in switched mode power supplies, audio amplifier applications, and DC/DC converters. It is also increasingly being used in digital circuits like CMOS logic chips, due to its lower temperature range and low frequency sensitivity.

In operation, the LQH43CN101K03L holds energy in the form of a magnetic field when a circuit is energized. When a voltage is applied, the inductor resists changes in current, allowing the voltage to rise slowly and the current gradually. This provides voltage regulation, since the actual voltage supplied is limited by the inductor\'s value.

The LQH43CN101K03L is part of a growing trend of high-frequency fixed inductors. With its excellent insulation performance, high inductance, and low profile, it is becoming increasingly popular in swift, high-power applications. As more designers strive for power-efficient designs, the LQH43CN101K03L is helping to meet those demands.
