Fixed inductors are specialized electrical components, primarily used in radio frequency (RF) circuitry. One of the most commonly installed fixed inductors is the 1812R-472K, a power chip inductor designed for use in various RF driver applications. Its 1812 size allows it to fit easily in most layouts.

The 1812R-472K is rated at 0.5 Arms, and features an inductance value of 4.7mH. This makes it suitable for situations in which efficiency is important, such as in high-power switching and linear-power converter applications. The component’s design ensures a low core loss, providing a better overall performance when used in high-power systems.

The 1812R-472K is constructed with a high-grade ferrite material, ensuring a long-term durability and stability. Its copper wire winding helps to reduce losses, and improve signal transfer and current flow. The inductor’s case is made from a ceramic that helps to further enhance the inductor’s power handling capability.

In addition, the 1812R-472K is designed to provide excellent EMI (electromagnetic interference) suppression. Its high frequency feature helps to block out external noise, preventing any potential issues that could affect overall system performance. With a typical insertion loss of 0.4dB, the inductor offers effective isolation from the system’s surrounding environment.

When installed, the 1812R-472K inductor will operate within a frequency range of 0.16-5.0GHz. Its maximum DC resistance is rated at 1.2 ohms, and its maximum DC current is 2.2A. Additionally, the inductor has a separation factor of 18dB and an operating temperature range from -55 to +125°C.

The working principle of the 1812R-472K inductor is quite simple. When connected to a power source, a current is generated in the inductor. This current then creates a magnetic field, and it is this field that induces an electromotive force in the inductor. This electromotive force is then used to support the voltage generated by the power source. The inductor’s winding helps to ensure a smooth flow of energy, and it is this energy that is eventually converted to the desired voltage.

The 1812R-472K is a popular choice for RF power applications, due to its simple design and features. Its compact size makes it ideal for use in tight spaces, and its high-grade materials ensure a long-term service life. With its excellent EMI suppression, high power handling capabilities, and impressive inductance values, the 1812R-472K can be an important addition in any high-power RF system where efficiency and reliability are priorities.
