Fixed inductors are electrical circuits designed to provide a fixed electrical resistance by creating a magnetic field. With various applications ranging from radio frequency filters and power amplifiers to antenna design, they are heavily used in a variety of electronic systems. One of the common fixed inductors is the NRS8040T220MJGJ. This inductor is designed for high heat resistance and power handling up to 8W.

The NRS8040T220MJGJ has a chip inductor package size of 2210, making it relatively small and cost-effective. It is constructed of windings formed with magnet wire in an air-core, with lamination coatings to increase its tolerance, performance, and temperature ratings. The inductor gives a current rating of 2.6A and a resistance of 0.22 Ohm.

The termination of the NRS8040T220MJGJ is tin-plated for additional corrosion resistance. The inductor has an operating temperature ranging from -55°C to 125°C, with a maximum temperature of 155°C and an ambient temperature of 85°C.

The NRS8040T220MJGJ is most commonly used as an antenna tuning element, as its lower series resistance at high frequencies ensures maximum efficiency and compactness. It is also ideal for power supplies and filtering applications, as well as radio frequency circuit design. Additionally, it is suitable for EMI/RFI noise suppression applications.

The working principle of the NRS8040T220MJGJ is based on the behavior of a coil when a current is passed through it. The current generates a magnetic field, which is in turn stored in the air core of the inductor. This stored magnetic energy can be released when the current is stopped, creating a voltage across the inductor. This reverses the direction of the current, thereby preventing it from continuing in the same direction.

This behavior allows inductors to oppose rapid changes of voltage or current, and is used to regulate the current flow in power circuits, filter out unwanted radio frequencies, and convert DC power to AC power. The NRS8040T220MJGJ has been optimized to take full advantage of this behavior, and its performance and efficiency in carrying out these applications are unsurpassed.
