Introduction
Fixed inductors, also known as chokes, are electronic components that are used to store electric energy in the form of a magnetic field. The DC1390-154K is a type of fixed inductor that is suitable for a wide range of applications. It is capable of providing a constant current and voltage for a variety of electronic devices. This article will discuss the applications and working principle of the DC1390-154K.Applications
The DC1390-154K is commonly used in power supplies, as it is able to regulate the output voltage to keep a constant voltage with minimal ripple. It is also used as a voltage regulator in various automotive applications, such as audio systems, airbags, and navigation systems. It can also be used in high voltage switching applications, such as motor control and power factor correction.The DC1390-154K is also suitable for use in radio frequency applications, as it is able to provide a frequency-dependent impedance to improve the performance of the device. It is also used in circuit protection applications, as it provides a current-limiting effect. Additionally, the DC1390-154K is suitable for pulse width modulation applications, as it can react quickly to rapid changes in the load.Working Principle
The DC1390-154K is an inductor, meaning that it is made of a coil of wire around a core. The coil is connected to two terminals and an AC (alternating current) or DC (direct current) voltage is applied to the terminals. When current passes through the coil, it produces a magnetic field that stores energy.When the current is constant, the inductor behaves as a resistance and only a small amount of current can flow. However, when there is a sudden change in the current, the inductor acts as a filter to reduce the ripple effect. It does this by forcing the current to build up slowly, limiting the peak current and voltage.The DC1390-154K is an “air core” type inductor, meaning that the core is made of nothing more than air. This allows for a higher inductance in a smaller size and a higher frequency response. The DC1390-154K is wound with a low resistance wire, allowing it to dissipate heat more efficiently.Conclusion
The DC1390-154K is a fixed inductor that is suitable for a wide range of applications, such as power supplies, voltage regulation, high voltage switching, radio frequency applications, circuit protection, and pulse width modulation. It consists of a coil of wire around an air core, allowing it to provide a frequency-dependent impedance and reduce the ripple effect when there is a sudden change in the current.
