Fixed Inductors are electrical components that store energy in the form of a magnetic field. They are used in a wide range of applications such as providing a source of inductive reactance, tuning oscillators, generating radio frequency current, filtering signals, and providing an impedance matching network for signal conditioning and power amplifiers. This article will discuss the application field and working principles of 0805-24NJ fixed inductors.

The 0805-24NJ is a relatively small, low-cost, surface mount inductor. It is usually used for miniature circuits, such as in capacitors or resistors, as they require minimal board space. This inductor is uniquely suited for high frequency applications up to 1GHz due to its compact size and low parasitic capacitance. Due to its small size, it can be used in portable electronic devices such as mobile phones and laptops.

The 0805-24NJ has a high inductance of up to 1.5nH and low dc resistance of 0.85 Ohm. It also has a high self-resonant frequency of 3GHz. The size is extremely small, measuring only 8.1mm in length and 4.6mm in width. This makes it suitable for dense circuit boards with limited available space.

The working principle of this inductor is quite simple. When current passes through the coil, it generates a magnetic field that stores the energy. This energy is released when the current flow is reversed. This principle is known as Faraday’s Law, and it is observed in all inductive devices. The 0805-24NJ inductor is designed to maintain an inductance level under a given amount of current. The specific inductance level will depend on the number of winding turns, the core material, and the total inductor area.

In terms of application, 0805-24NJ fixed inductors are most commonly used in radio frequency (RF) circuits, switching power supply applications, and signal filtering applications. In RF circuits, fixed inductors are used for impedance matching and wave shaping circuits. In switching power supply circuits, they are used for radio frequency interference (EMI) suppression, and in signal filtering applications, they are used to reduce noise in power amplifiers and digital signal processing circuits.

In conclusion, 0805-24NJ fixed inductors are small, low-cost and high-frequency electrical components that are widely used in a range of applications. By understanding their working principle, we can better utilize their features for various applications.
