Introducing Knowles' High-Q Ceramic Core Inductors

Ceramic core inductors are critical components in RF and microwave circuits, valued for their stable inductance and consistent performance across wide frequency ranges. These inductors are essential in applications demanding low loss and high efficiency at high frequencies, such as signal filtering, impedance matching, and energy storage.

Knowles offers high-Q ceramic core inductors designed to meet the needs of both standard and high-reliability applications. Their high Q factor reduces signal loss, improving RF efficiency, clarity, and reducing distortion. With superior self-resonant frequencies (SRF) extending into the gigahertz range, these inductors minimize energy loss and maximize power transfer efficiency in demanding high-frequency environments.

Reliability is a key attribute, as Knowles’ inductors are built to withstand harsh operational conditions, making them ideal for mission-critical uses. Industries benefiting from these inductors include medical imaging—where they improve MRI clarity and reduce interference; defense and aerospace—supporting radar, secure communications, and advanced signal processing; and industrial and avionics sectors, where efficient power delivery and signal filtering ensure stable operation.

By expanding its RF component portfolio, Knowles empowers engineers to design with confidence, providing high-performance inductors that meet rigorous demands for efficiency, reliability, and precision. These inductors are integral to optimizing circuit performance in applications where excellence is non-negotiable.
