Fixed InductorsA fixed inductor is an electronic component with a coil of insulated wire that develops an electromagnetic field when current flows through it, and which stores energy when current flow is stopped. ASPI-0309-470M-T4 is one such inductor. This article will explore the application field and working principle of the ASPI-0309-470M-T4 fixed inductor.An inductor\'s application field is typically determined by its electrical properties, such as inductance, resistance, Q-factor, self-resonant frequency, and maximum working frequency. The ASPI-0309-470M-T4 fixed inductor has an inductance of 470mH, a resistance of 24.7Ω, a Q-factor of 50, and a self-resonant frequency of 297MHz. This makes it suitable for use in DC-DC converters, signal processing circuits, switch mode power supplies (SMPS), and high-frequency filters.The working principle of the ASPI-0309-470M-T4 fixed inductor is based on Faraday\'s Law of Induction. This states that when a conductor (such as the coil of the inductor) is subjected to a changing magnetic field, it will generate an electric current. When current passes through the coil of the inductor, a magnetic field is set up around the coil. When the current is stopped, the magnetic field collapses and generates an opposing voltage, which can be used to store energy. This is how the ASPI-0309-470M-T4 fixed inductor works.In addition to the aforementioned electrical properties, the ASPI-0309-470M-T4 fixed inductor also has a high rated current of 400mA and a saturation current of 630mA. This makes it capable of dissipating up to 490mW of power, making it suitable for use in high-power applications such as DC-DC converters and SMPS.The ASPI-0309-470M-T4 fixed inductor is also highly reliable, with a rated voltage of 100V and a dielectric strength of 7kV. This makes it suitable for use in harsh electrical environments, where it is exposed to high voltages and temperatures.In summary, the ASPI-0309-470M-T4 fixed inductor is a highly reliable and versatile component that is suitable for a wide range of applications. It features a high inductance, resistance, Q-factor, self-resonant frequency, and maximum working frequency, making it suitable for use in DC-DC converters, signal processing circuits, switch mode power supplies (SMPS), high-frequency filters and other applications. It also has a high rated current and saturation current, enabling it to dissipate up to 490mW of power. It also has a rated voltage of 100V and dielectric strength of 7kV, making it suitable for use in harsh electrical environments.
