Fixed Inductors
Fixed inductors, also called chokes, are devices used to control the flow of current in an electrical circuit by creating an opposition to the change of current. They are typically considered low frequency components, meaning they are designed to operate at frequencies lower than 1 MHz. Fixed inductors are widely used in power supplies, audio systems, automotive applications, telecom systems, and RF/microwave systems.The HL021R8BTTR is a Class I, fixed inductor from KEMET Electronics. It is a surface-mount component measuring 8.4 x 8.4 mm with a 3.2 mm max height profile. This model can handle up to 10 A of continuous current and 15 A of pulsed current. It has a maximum DCR rating of 2.3 mΩ and provides a maximum self-resonant frequency of 11 MHz in a 100 kHz field. KEMET claims that this device has reduced high frequency heating and low EMI noise emissions.The working principle of a fixed inductor is very simple. It is simply an inductor wound with a coil of wire and is used to control the current in a circuit. The inductor creates a magnetic field when current is applied to the coil. This magnetic field then opposes the current flowing through it. That is, the current is limited by the opposition of the inductor\'s magnetic field. Consequently, the inductor is able to limit the current in the circuit, while also eliminating harmful high-frequency noise.The HL021R8BTTR fixed inductor is ideal for applications where high current rating and noise reduction are a priority. The device can be used in power supplies, motor drive circuits, engine controllers, switching power converters, electrolysis cell controllers, lighting dimmers, and more. The device has been tested and certified according to UL 60950 and is RoHS compliant.In order to better understand the implementation of a fixed inductor, let\'s explore its basic structure and function. An inductor is composed of a wire coil and a ferrous core material. When current is applied to an inductor, a magnetic field is generated. This magnetic field then creates a resistance to the flow of current. This inductance will limit the current in a circuit to the amount of opposition desired.The HL021R8BTTR is a great choice for applications where the current needs to be restricted and for noise reduction. It has a well-designed core structure, allowing for maximum efficiency and reduced EMI noise. Additionally, the device meets safety standards and is RoHS compliant. This makes it a reliable choice for commercial electronic products.Fixed inductors are essential components in many power supplies, audio, telecom, automotive, and RF/microwave systems. The HL021R8BTTR fixed inductor is a great option for those who need a high current rating and noise reduction. With its Class I design, ferrite core material, and UL and RoHS compliance, it is a well-engineered and reliable choice.The specific data is subject to PDF, and the above content is for reference
