Fixed inductors are essential components for electronic products. They are mainly used to filter power supply signals, block radio signals, and store energy. In particular, the SC75-120 is a type of fixed inductor with a wide range of applications in various electronic projects. In this article, we will discuss the application field and working principle of SC75-120.

The SC75-120 is a high current, low-resistance fixed inductor specially designed for use in consumer products such as mobile phones, tablets, and computers. It can also be used in automotive and military applications. This inductor is designed to reduce radiated noise, minimize voltage fluctuations, and reduce power consumption. It also helps prevent short circuits and absorbs high-frequency currents.

Its application field includes DC/DC converters, voltage regulators, filters, clocks, and power supplies. Since it is designed for light load operation, it is ideal for applications requiring high efficiency and low power consumption. It is also used in switch-mode power supplies, motor drives, and other applications that require low-resistance and high current.

The working principle is based on the effect of a fixed inductor in an AC circuit. When an alternating electric current passes through the inductor, it produces a time-varying magnetic flux, which in turn induces a voltage across the inductor. This voltage, known as the EMF, is proportional to the rate of change of the flux and is measured in volts per second or amperes per second. The SC75-120 uses this property to filter out unwanted noise and reduce power consumption.

The SC75-120 has a wide range of features that make it ideal for use in commercial and consumer electronic applications. It has a series resistance rating of less than 0.1 ohms and a high current rating of 120 mA with peak currents of up to 250 mA. It also has a high frequency range from 1 kHz to 10 MHz. Moreover, its self-resonance frequency is at 10 MHz, which makes it suitable for noise cancellation applications.

In conclusion, the SC75-120 is a high current, low-resistance fixed inductor that is widely used in many electronic applications. It is designed to reduce noise, minimize voltage fluctuations, and reduce power consumption. It is ideal for DC/DC converters, voltage regulators, filters, clocks, and power supplies. Finally, it uses the effect of a fixed inductor in an AC circuit to filter unwanted noise and reduce power consumption.
