Fixed Inductors - NRS8040T100MJGJ

Fixed Inductors are electronic components whose purpose is to store electrical energy temporarily in the form of a magnetic field. They are widely used in filters and chokes, power supplies, and consumer electronics. The NRS8040T100MJGJ is an example of a fixed inductor and is designed for use in high-performance automotive, aerospace, and military applications.

Application Field

The NRS8040T100MJGJ is a miniature, radial-leaded wire-wound fixed inductor designed for use in high-performance automotive, aerospace, and military applications. The component is capable of operating in temperatures up to 150°C, and features an isolation voltage of 250V. Due to its high inductance, 3.2µH per inch of air gap, and low DC resistance, the component is ideal for use in high-frequency power supplies, saturation and soft-switching applications, resonant circuits, and SMPS filtering.

Working Principle

The basic operating principle of a fixed inductor is based on Faraday\'s Law of Induction, which states that a time-varying magnetic field induces an electric field in a nearby conductor. This electric field in turn produces a "back EMF," or voltage, that opposes the original voltage source. This opposition effectively "chokes off" some of the current, and is referred to as inductance.

In an ideal fixed inductor, the amount of inductance remains constant regardless of the source frequency. In practice, the inductance will change depending on the source frequency, and may even completely saturate at high frequencies. As such, fixed inductors are optimized for use at certain frequencies, and must be chosen carefully to ensure the inductance is appropriate for the given application.

Conclusion

The NRS8040T100MJGJ is a miniature, high-performance fixed inductor capable of operating up to 150°C and featuring an isolation voltage of 250V. Due to its high inductance, 3.2µH per inch of air gap, and low DC resistance, the component is suitable for use in high-frequency power supplies, saturation and soft-switching applications, resonant circuits, and SMPS filtering.
