Fixed inductors are components that are used to store electrical energy in a magnetic field. In an inductor, a current passing through a coil of wire creates a magnetic field. This field, when concentrated, can store energy in the form of a magnetic field for a given current. Inductors are commonly used in radio frequency (RF) and audio applications, such as for antenna couplers, transformers and filters.The ELL-4GM4R7N is a fixed inductor designed to serve a wide range of applications. It is a SMD type product with a shielded core, capable of operating in frequencies up to 4GHz. The inductor has a high inductance value of 4.4µH, allowing it to be used as an antenna’s matching network, and is designed to operate at a wide temperature range from -55 to +140 °C.The ELL-4GM4R7N is a single layer core inductor, composed of a central shielded core with two windings of aluminum-titanium wire. The core allows for a high level of signal integrity, while the windings are designed to minimize signal loss. The inductor has a low equivalent series resistance (ESR), typically ranging from 0.10 to 0.15 Ω, ensuring it does not interfere with the operation of the circuit.The ELL-4GM4R7N is a reliable inductor, designed to work in a wide variety of environments and applications. Its shielded core offers improved efficiency and reduced crosstalk, making it suitable for high-frequency applications. It can be used in applications as diverse as RF communication, signal and power conditioning, and filtering circuits.To produce a consistent inductance value with low tolerance, the ELL-4GM4R7N is designed to maintain a constant number of turns in each winding. The number of turns of the windings is accurately counted using a mechanical counter. The inductor is then subjected to a test to ensure the desired inductance value is maintained when placed in an external circuit.In addition, ELL-4GM4R7N has good quality insulation with a breakdown voltage of 400V, allowing it to be used in high-voltage applications. Furthermore, its construction allows it to be placed in close proximity to other components, helping reduce size and cost.Overall, the ELL-4GM4R7N is an excellent choice for high-frequency applications where signal integrity and low losses are desired. Its shielded construction allows it to provide a stable output, even in highly capacitive environments, making it suitable for antenna matching networks and RF communication circuits. It is a versatile and reliable product, capable of handling a wide variety of high-output applications.
