Fixed InductorsFixed inductors, also known as inductors, choke coils, or storage coils, are electronic components used to create inductance in an electrical circuit. Fixed inductors are typically composed of an inductor coil wrapped around a core material. The inductor may be wound out of a single conductor or may be composed of a number of strands of wire. The core material used for fixed inductors can vary, including powdered iron, ferrite, ceramic, and air.ELJ-RE4N7JFA is a fixed inductor manufactured by Murata Electronics. This particular product is a shielded radial leaded fixed inductor, designed for use with power supply, DC-DC converter, charger, and automotive audio applications. The product supports operating frequency of up to 400kHz and an operating temperature range of -40°C to +105°C. It has a saturation current rating of 5.23A and an inductance value of 0.8µH. The product also has a radial lead spacing of 4.0mm.ELJ-RE4N7JFA works by providing electrical resistance, or inductance, in the form of a magnetic field. This field opposes the current passing through it, creating an inductive reactance. Inductance is the property of a conductor that resists the abrupt change in current flow and is measured in henry (H). When connected in series with a circuit, the devices inductance will limit the rate of change of current in the circuit. As a result, energy stored in the magnetic field dissipates slowly, preventing sudden surges of current that could be damaging.Fixed inductors like the ELJ-RE4N7JFA can be used in a variety of applications, were precise control of current is desired. Examples include power supplies, DC-DC converters, audio amplifiers, radio frequency (RF) circuits, and switching power supplies. This particular inductor is also useful in automotive audio applications such as car head units, radios, and amplifiers, where it helps to control the current flowing into the system\'s speakers. Due to its small size and excellent performance, the ELJ-RE4N7JFA has become a popular choice for many applications. This inductor features excellent noise suppression and low magnetic flux leakage when connected in series with a circuit, making it ideal for noise reduction. Additionally, it requires very little board space, allowing for simpler circuit designs and reduced space requirements. The product also has an inductance tolerance of ±20%, providing accurate and precise control of the current in an application. Overall, the ELJ-RE4N7JFA is an excellent choice for a wide range of fixed inductor applications, offering superior performance and reliable operation. With its small size, low leakage, and excellent noise suppression, this product has proven to be a reliable and cost-effective solution for many applications.
