Fixed Inductors
Sometimes referred to as coil, inductor or choke, fixed inductors are passive electronic components which store energy in a magnetic field. They are widely used in consumer and industrial applications, such as filter circuits, power supplies, audio and other electronic circuitry. Fixed inductors come in various shapes and sizes, depending on the application requirements. One such example is the SDR0403-121KL, a high-power inductor commonly used in power transistors. Below, we discuss the application field and working principle of the SDR0403-121KL.
Application Field
The SDR0403-121KL is a wide temperature range inductor, ideal for applications that require high power in high temperature environments. It features a low DC resistance of 0.0047ohms and maximum current capacity of 6.7 Amps. The SDR0403-121KL is also suitable for high frequency circuits, with an inductance range of 0.11~0.13 mH. It is highly durable and reliable, being able to withstand up to 125°C temperature rating. Due to its excellent power efficiency and relatively low cost, the SDR0403-121KL is well-suited to various applications, such as automotive electronics, medical electronics, power electronics, LED lighting and more.
Working Principle
Once connected, electricity passes through the SDR0403-121KL, increasing the inductor\'s magnetic field. The inductor then stores the magnetic field energy. This energy is later depleted as the current decreases. An inductor has a direct relationship between the current and the energy stored. The more current that flows through the inductor, the more energy is stored in the inductor. Since current needs to flow through the inductor in order to generate a magnetic field, the inductor can regulate the amount of current that is passed through it.
The amount of current regulation depends on the frequency of the applied signal. Since a high-frequency signal passes through the inductor more quickly than a low-frequency signal, a high-frequency signal causes less current regulation than a low-frequency signal. The SDR0403-121KL is highly efficient at regulating the amount of current passing through it, making it suitable for high-current applications operating in high temperature environments.
The SDR0403-121KL fixed inductor is a reliable component that is widely used in many power-related applications. It has low DC resistance and a long-term temperature rating of up to 125°C. With a maximum current capacity of 6.7 Amps, the SDR0403-121KL is ideal for applications that require both high power and reliability. Additionally, its ability to regulate current levels makes it perfect for high-frequency applications as well.
