Fixed Inductors are widely used in the field of electronics for their ability to provide inductance in electrical circuits. The ER1840-109JR is one of the most popular varieties of these inductors, and is commonly used in applications such as consumer electronics, communications, instrumentation, and automotive.

The ER1840-109JR is a high-grade, lead-frame based, 28°C polarized, snap-in type, ferrite core inductor. Its construction consists of a ferrite core, an enameled copper wire, an epoxy glue, and a metal snap-in plate. This inductor is designed for surface mounting and has a 10 mm diameter by 9.7 mm height with a total height of 10.7 mm. The ER1840-109JR has a rated current of 1.1A and the inductance is measured at 100MHz. It offers a maximum self-resonance frequency of 24MHz and a working temperature range of -40°C to +125°C

The working principle of the ER1840-109JR is similar to that of other fixed inductor types. The core consists of magnetically permeable material that allows a magnetic field to be created by the current passing through the conductive coil windings wound around the core, thereby creating an inductance. As the current increases, the magnetic field also increases, creating a storage of energy due to inductance. This stored energy is then released as the current is decreased, creating an electromotive force. The inductors are usually connected to a capacitor or a resistor, depending on the application, in order to prevent the release of energy from becoming a circulating current.

The ER1840-109JR is a popular choice for those looking for high-grade, reliable fixed inductor models. It provides good performance and can withstand temperature changes, making it perfect for a variety of applications. Its small size and wide temperature range also make it an ideal choice for applications where space is at a premium.

Those looking for quality yet affordable fixed inductors should consider the ER1840-109JR model. With its competitive discount price and reliable performance, this model is a great choice for those looking for an affordable and versatile fixed inductor solution.
