SC4020FH-470

Fixed inductors, also known as chokes, coils or reactors, are passive electrical components used in electrical circuits to provide inductance, that is, to limit the flow of direct current or to provide electrical energy storage.The SC4020FH-470 is a fixed inductor created and manufactured by Sumida Electric Co., Ltd. and is typically used in electronic devices such as switching power supplies and switch-mode power supplies, mobile phones, mobile memory modules, digital cameras, robotic devices, automotive systems, voice recognition, and communications systems.The SC4020FH-470 offers four primary features: inductance, high current capability, low magnetic flux leakage, and small size. Its inductance value offers high-speed response for power electronics applications, such as switching power supplies and switch-mode power supplies. The inductance value ranges from 0.220 µH to 0.680 µH, which ensures stable operation over a wide frequency range.The SC4020FH-470 also has a high current capability, allowing it to handle high current levels in a small package size. This makes it ideal for use in high-power applications, such as servos and motor control applications. The high current capability ensures less power is dissipated and a longer life expectancy.In addition, the SC4020FH-470 has a low magnetic flux leakage. This prevents external interference, which can cause malfunctions or data errors, and allows for effective signal control with extremely stable frequency characteristics. Furthermore, its small size contributes to high miniaturization, saving time and effort when assembling and wiring circuits.The SC4020FH-470 fixed inductor operates using Faraday\'s law of induction. According to this law, when an electric current produces a magnetic field, an electromagnetic force is produced. The force generated by the current in the inductor provides impedance to the current. This slows the current, opposing any changes of the current in the circuit. The amount of impedance is determined by the inductance, which is a function of the number of turns in the coil. As the number of turns increases, the inductance also increases and the inductor’s impedance increases, slowing the current down even more.To sum up, the SC4020FH-470 offers a variety of features, such as high inductance, high current capability, low magnetic flux leakage, and small size, which enable it to be used in a variety of applications. Its ability to provide highly stable frequency characteristics using Faraday\'s law of induction makes it the ideal choice for power electronic applications.
