Schematic Diagram Surface Mount Inductor Toroid Mount meets UL94VO 1 : 1 +1% Designed for IR and Vapor Phase Reflow The Inductor is a dual winding and can be used as a dual inductor, single inductor, or a transformer. Single inductors can be wired in series for high inductance values or wired in parallel for less inductance but twice the current capacity. As a 1:1 transformer, it can provide a minimum of 500 volts isolation with good frequency response. For series operation Connect 2 & 4 For parallel operation Connect 1 & 4 and 2 & 3 Electrical Specifications at 25o C --------------- Series Ratings ------------------L DCR I L E-T + 20% Max.
