Surface Mount Inductors Toroid Mount meets UL94VO Designed for IR & Vapor Phase Reflow Processes For use as a dual inductor, single inductor, or transformer. Connect in series for high inductance values or wired in parallel for less inductance, but twice the current capacity. As a 1:1 transformer, they can provide a minimum of 500 volts isolation with good frequency response. These parts are manufactured using Sendust material. Lower cost versions of these products are available using powdered iron, however, there is an increase in core loss.
