Fixed inductors, also known as fixed chokes, are unchangeable components in the form of coils which exhibit a known impedance and inductance within the limits of a given customer or application specification. The ELJ-NJ12NGF2 is a high-performance fixed inductor designed to meet the requirements of a variety of applications. This product is manufactured using advanced winding technology in order to reduce DCR (DC Resistance) and provide superior inductance stability.

The ELJ-NJ12NGF2 is primarily used in the power supply and AC/DC converters of various systems. It is ideal for applications requiring low DCR and able to meet the requirements of high peak current loads. The operating temperature range for this product is from -55°C to 125°C, making it suitable for a variety of environmental requirements.

Working principle wise, the ELJ-NJ12NGF2 is based on Faraday’s law, which states that the rate of change of the electromotive force (EMF) in a closed circuit is proportional to the rate of change of the magnetic flux linked with the circuit. In other words, when a coil is subjected to a changing magnetic field generated by alternating current (AC), it induces an EMF in the coil itself, otherwise known as self-inductance. This self-inductance, measured in Henries (H), is defined by the number of turns of wire of a given material, its diameter, and its length. To put it simply, a fixed inductor is a coil whose inductance is electromagnetically fixed.

In order to account for the influence of the surrounding air in these components, the ELJ-NJ12NGF2 fixed inductor is constructed with two winding layers, one on the inside and the other one on the outside. This design makes the product capable of decreasing the reduction in magnetic flux due to the air as much as possible, in addition to improving noise immunity and reliability. The overall structure provides superior high frequency characteristics and high rated current characteristics.

When it comes to features and specifications, the ELJ-NJ12NGF2 includes extremely low DCR, up to 6.2A rated current, up to 1.4uH inductive parameters, up to 400MHz resonant frequency, and up to 40V rated voltage. These qualities make the ELJ-NJ12NGF2 ideal for various power management systems such as switching power supplies, LED drivers, and various AC/DC applications. It can also be used in various electronic circuits, such as output filters, low-noise amplifiers, and radio frequency output filters.

Overall, the ELJ-NJ12NGF2 is a modern fixed inductor with various features that make it ideal for high power applications. Its advanced winding technology reduces DCR and offers superior stability, while its two-layer windings allow for better noise immunity and higher efficiency. Due to its impressive features and specifications, the product is suitable for a wide variety of power management systems.
