Riverside, California – October 20, 2021 – Effective April 16, 2022, Bourns will change the inductor terminal plating method for the Model SRR3818A Series Shielded Power Inductors. The current plating method, physical vapor deposition (PVD), will be changed to barrel plating. In the PVD plating method, the Fe/Ni/Cu coating is processed in one procedure. The thickness of the metal layer is unidentifiable during QA inspection. In the barrel plating method, the Ag/Ni/Sn coating is processed separately.
