Multilayer Ferrite Chip Beads | High Current Power Inductor Manufacturer | Coilmaster Electronics
Manufacturer of SMD multilayer ferrite chip beads, EMI suppression beads, high-frequency noise filter. Multilayer ferrite chip beads are designed to suppress high-frequency noise and improve EMI performance in electronic circuits. Constructed with ferrite ceramic material, they offer high permeability for effective attenuation at high frequencies, while maintaining low loss at low frequencies. Impedance (Z) is typically measured at 100 MHz, where ferrite beads provide their highest effectiveness. The impedance profile is mostly resistive (R component), enabling efficient absorption and dissipation of unwanted noise energy. Ferrite chip beads are also referred to as ferrite blocks or SMD EMI filters and are widely used due to their cost efficiency, compact size, and broad range of electrical characteristics. Coilmaster Electronics is a high-current High Current Power Inductors, Automotive Grade Chokes & Inductors,High Frequency and Planar Transformers, LAN Magnetics (RJ45), Multilayer Chip Beads manufacturer from Taiwan since 1995. Coilmaster offers AEC-Q200 certified, high-efficiency power inductors, chokes, and transformers. Specializing in low-loss, high-current components for Automotive, 5G, and Industrial applications. Contact our experts for instant support. With more than 20 years of experience in magnetic territory, Coilmaster Electronics is specialized in the production of SMD power inductors, common mode choke, high frequency transformers.
