Fixed inductors are electrical components in which the inductance value is fixed by the physical shape, size and type of core material. In this category, the LLSTR-140 application field and working principle are particularly noteworthy. The LLSTR-140 is a fourth generation, high-performance integrated mixed-signal device for hard disk applications that combine low power analog and digital signal processing capabilities with support for high-speed DDR3L, Capacitive Multi-Touch, and other types of integrated interfaces. The device employs an energy-efficient innovative architecture that reduces power consumption and cost. LLSTR-140 is designed for applications requiring low power analog and digital signal processing capabilities, such as hard disk applications.

The LLSTR-140 includes two power capacitors, two 4-bit data paths, a 4-bit control circuit, and a 2-Wire Serial Interface. The power capacitors are connected to the power pins and allow for independent control of the power current for each device. The two 4-bit data paths are used for data transfer between the device and an external memory. The 4-bit control circuit is used for controlling the data flow and the direction of the data transfer. The 2-Wire Serial Interface is used for communication between the device and an external controller. The LLSTR-140 has a maximum operating voltage of 5V, and a supply current of up to 10mA.

The LLSTR-140 works with the DC-Biased Circuit method. This method uses a voltage reference and a current source to determine the inductance of the inductor. The voltage reference and the current source are connected to the input of the LLSTR-140. The current through the inductor is compared to the voltage reference and the current source. From this, the net inductance is determined and used to calculate the inductance value. The circuit is then configured to achieve the desired inductance value.

The LLSTR-140 can also be used in a Resonance Circuit for applications requiring precise resonance tuning. The Resonance Circuit uses an inductance value to match that of the device to ensure high-precision tuning performance. The circuit is configured to maintain a constant resonance frequency by adjusting the inductance value as the device changes with conditions. In this way, high-precision tuning performance is maintained.

The LLSTR-140 is suitable for hard disk applications and other low-power analog and digital signal processing applications, due to its ultra-low power consumption and its low inductance values. The device\'s use of the DC-Biased Circuit method and the Resonance Circuit make it an extremely versatile and efficient inductor for high-precision applications. In addition, its low-cost makes it an affordable component for use in a wide variety of applications.
