Fixed Inductors

Inductors have been used for centuries. They are the building blocks of electrical networks that enable a variety of functions and applications. Fixed inductors are used to manage ACs, DCs, and other signals. Fixed inductors include the 4554R-391K, a model that is specifically designed for high-frequency, low-noise applications. In this article, we will discuss the application field and working principle of the 4554R-391K.

Application Field

The 4554R-391K is a rugged and reliable low-noise fixed inductor that is ideal for high-frequency applications such as filters, power supplies, RF signal filtering, and data transmission. The 4554R-391K is designed to operate in temperatures ranging from -40°C to 85°C and features a wide operating frequency range of 0.1 to 20 MHz. It is also designed with low leakage inductance and low DC resistance for reduced noise and signal distortion.

Working Principle

The 4554R-391K operates on the principle of inductance, whereby a coil of wire creates a varying magnetic field when electricity is applied, inducing an opposing electrical field in another coil of wire. This opposing field acts as a type of resistance, which can be used to regulate power flow. The 4554R-391K is designed with a high inductance value of 1.77 mH, which allows it to effectively pass low-frequency signals without interference.The 4554R-391K is also designed with a low DC resistance of just 0.08 ohms which reduces signal loss and distortion. The coil is small and compact, making it ideal for small and densely packed design applications. The 4554R-391K also features a shielded construction with copper-clad aluminum windings to reduce electrical interference and ensure stable operations.

Conclusion

The 4554R-391K is an ideal fixed inductor for high-frequency applications such as filters, power supplies, RF signal filtering, and data transmission. Its wide operating frequency range of 0.1 to 20 MHz, along with high inductance of 1.77 mH, low DC resistance of 0.08 ohms, and shielded construction make it a reliable and robust solution for reducing noise and signal distortion in applications where high accuracy and precision are essential.
