It has a rated current of 5A DC and a rated power of 2W at 70℃ with a tolerance of 10%. These features make the 4922R-33J an ideal component for audio and computer applications.

Application fields

The 4922R-33J is mainly used in audio and computer applications such as in analog power amplifiers, audio filters, radio receivers and transmitters. It is also used in high-frequency switching power supplies as an output inductor. It can even be used in audio crossover networks in order to reduce unwanted frequencies. Moreover, it can be used in low-noise and low-EMI circuits.

Working Principle

The 4922R-33J is based on the principle of inductance. When an electric current flows through the inductor, it generates a magnetic field. This magnetic field produces the inductance, which opposes a change in the current. Therefore, it acts as a filter to allow only certain frequencies and blocks out the rest. The strength of the inductance is determined by the size and shape of the inductor, as well as the number of turns of wire in the coil.

The 4922R-33J is designed with a special type of winding called “bifilar winding”. This type of winding allows the inductor to maintain a good temperature stability and resistance to EMI. Moreover, the winding also reduces the effect of core losses, which leads to a better current efficiency.

In conclusion, the 4922R-33J is a high-efficiency, high-stability fixed inductor ideal for audio and computer applications. It is based on the principles of inductance with a special bifilar winding that improves temperature stability and reduces EMI effects. This makes it an ideal choice for a variety of audio and electronic applications.
