Fixed InductorsFixed inductors are passive components used in electronics in a wide variety of applications such as power conversion, radio frequency, and electronic circuits. A fixed inductor is a self-contained device composed of one or several coils of wire. Its purpose is to provide opposition to any change in the current passing through the inductor.The LB3218T680K is a general-purpose, fixed-inductor (chip) which provides good magnetic and RF characteristics. It is designed for high reliability, low EMI, and simple installation. Based on separate core technology, it is suitable for a wide range of applications such as audio, automotive, and telecom.The LB3218T680K has a range of features that make it an ideal choice for a wide range of applications. It has a high inductance value of 680μH and an operating frequency range of 0.1MHz to 5 MHz. It has a high efficiency of ≥90% and a maximum current rating of 250mA. It also has a very low ESR (equivalent series resistance) of 0.28Ω, making it suitable for high-power applications. It offers excellent cost to performance ratio and is available in a variety of packages.The LB3218T680K is designed to work with widebands, high frequence switching applications, and low-frequency line filtering. Its inductance value of 680μH makes it an ideal choice for applications that require good performance without sacrificing size or cost.The LB3218T680K works on the principle of inductance, which states that when a conductive loop (coil) is placed in a magnetic field, it will induce a current in the conductor. This electric current in the loop is proportional to the rate of change of the magnetic field. As the current increases in the th coil, a voltage will be induced in the conductor due to the resistance of the coil. This voltage is known as inductance. When an alternating current is applied to the input, the inductor acts like a filter to regulate the current, allowing only frequencies that pass the desired range to pass. By regulating the current this way, it eliminates the spikes and other distortion caused by a noisy power supply.In addition, the LB3218T680K can also be used for noise filtering. It can be used to reduce the voltage spikes caused by external interference, and it can also be used to reduce the electrical noise generated by other components in a circuit.The LB3218T680K is an ideal choice for a wide range of applications and is suitable for high reliability, low EMI, and simple installation. It has proven to be very reliable and cost-effective for applications such as switching, line filtering, and noise filtering.
