Fixed inductors are basic components in many electronics circuits, playing a key role in controlling their impedance. The RCH875NP-470K is a small, surface-mountable, high-efficiency fixed inductor, and is suitable for use in a range of circuits operating in the 0 – 7GHz frequency range. In this article, we will provide detailed information on its application field and working principle.

The RCH875NP-470K is an exceptionally powerful and durable fixed inductor, and it can survive operating temperatures ranging from -30˚C to +120˚C. Its high power capability – assured in a compact surface-mountable package – means that it is the perfect choice for use in a range of circuits. These include, but are not limited to, mobile transceivers, cable TV amplifiers, resonators, switching power supplies, switching regulators, TV signal tuners, pulse transformers, and sound systems.

The RCH875NP-470K is especially suited for applications with limited space, owing to its small size (5.5mm x 5.5mm x 2.8mm) and ultra-thin (0.6mm) design. Moreover, the conductive structure enables stable Self-Resonant Frequency (SRF), Q-factor, and current capability. Last but not least, its high Epoxy-Molding Compound (EMC) grade makes it ideal for use in high-level radar and communication systems.

The RCH875NP-470K is constructed from a printed circuit board (PCB) with two types of metal layers. The first is copper-plated copper metal, which forms an inductive coil. The second is a ferrite substrate, which is a type of magnetic material made of special ferrite powder. Since ferrite is a non-conductive material, it is used to prevent electromagnetic interference.

The inductor is composed of an air-core inductor (the copper-plated copper metal layer) and a magnetic core (the ferrite substrate). The air-core inductor stores energy in the form of a magnetic flux, while the magnetic core concentrates this flux in a controlled manner. This combination of air-core and magnetic core enables the inductor to efficiently store and release an alternating magnetic field.

The RCH875NP-470K effectively attenuates high frequency signals. Its magnetic and air-core components interact and filter high frequency components in an alternating signal, creating an alternating magnetic field thanks to the storage and release of energy from the air-core inductor and the magnetic core. This ultimately reduces the high frequency component of the signal.

The RCH875NP-470K is a highly powerful and durable fixed inductor, capable of attenuating high frequency signals in a range of applications. Its compact size and non-conductive design make it the ideal choice for limited space applications, while its high-grade Epoxy-Molding Compound provides long-term functional stability and electronic reliability.
