Introduction to LLST-350 Fixed InductorsFixed inductors are electrical components commonly used to store energy in a magnetic field. They are typically used in a variety of electrical circuits, such as filter circuits, power supply circuits, switching regulator circuits, and communications circuits. The LLST-350 is a type of fixed inductor manufactured by TDK Corporation of Japan. It is a highly reliable and cost-effective component designed for use in circuits where inductance is required.Features of LLST-350The LLST-350 is a radial leaded, radial wound, surface mount inductor with an inductance value of 350µH. It is a RoHS compliant component, meaning it is free of hazardous materials such as lead, mercury, and cadmium. Additionally, it is constructed from a dielectric core material, which provides a greater resistance to microwaves. Furthermore, it has a low DCR (DC resistance value) of 0.12Ω, allowing for efficient circuit operation. This is especially true when operating at higher frequencies, such as in switching regulator circuits.LLST-350 Applications and Working PrincipleThe LLST-350 is primarily used in filter circuits and power supply circuits, although it can also be used in communications circuits and various other types of applications. In filter circuits, its inductance value of 350µH helps reduce high frequency noise and helps improve the overall signal quality of the circuit. In power supply circuits, the LLST-350 can be used to store and release energy, helping to regulate the voltage and current of the circuit.The working principle of the LLST-350 is based on Faraday\'s Law of Induction. When a component is placed into a changing magnetic field, voltages will be induced in the component. In the LLST-350, this voltage is used to create and sustain a magnetic field, which in turn stores electrical energy. When a current is applied to the component, the stored energy will be released, creating a current within the circuit. This current can be used to increase or decrease the voltage within the circuit, thus helping to regulate the power supply.ConclusionThe LLST-350 is a reliable and cost-effective fixed inductor securement designed for use in circuits where inductance is necessary. Its 350uH inductance value makes it suitable for a wide variety of applications, such as filter circuits, power supply circuits, and communications circuits. In these circuits, the principle of Faraday’s Law of Induction is used to convert electrical energy into a magnetic field, which is then used to store and release energy, helping to regulate the voltage and current within the circuit.
