Fixed Inductors

Fixed inductors, often referred to as chokes, are electrical components designed to store energy in the form of electromagnetic fields. They are commonly used for filtering, antenna tuning, impedance matching, and voltage transformation. The ER1840-00JM is a type of fixed inductor designed to meet the demands of professional applications.

Specifically, the ER1840-00JM is a low profile, 10-turn coreless ferrite inductor with protective parylene coating. Its main features include high inductance stability, excellent Q factor, and small footprint. Additionally, the inductor is rated for temperatures ranging from -55C to +120C and frequent thermal shock, ensuring reliable operation even in adverse conditions.

The ER1840-00JM fixed inductor is suitable for a variety of applications where reliable performance is required. These include medical devices, avionic systems, telecommunications, embedded computing, and military communications.

The working principle of the ER1840-00JM fixed inductor is based on the principle of electromagnetic induction. When a current is passed through the inductor, it creates a magnetic field, which in turn creates a voltage difference across the device. This voltage difference is used to maintain a steady flow of current, despite changes in load impedance. Thus, the inductor acts as a filter, preventing an unwanted DC component from transferring across the device. Additionally, the inductor helps to limit the rate of rise of current, reducing the risk of damage to other components.

In conclusion, the ER1840-00JM is a high-performance fixed inductor suitable for a range of professional applications. It offers excellent stability, high Q factor, and a robust design, with wide temperature and thermal shock ratings. Furthermore, the device operates on the principle of electromagnetic induction, forming an effective filter and providing protection against excessive currents.
