Product Overview
The SG73 series Anti Surge Flat Chip Resistors are designed for applications requiring superior surge and pulse voltage withstanding capabilities compared to standard chip resistors. These thick film resistors are suitable for both reflow and wave soldering, feature lead-free terminations meeting EU-RoHS requirements, and are AEC-Q200 qualified. They are ideal for use in engine control units and circuits designed to handle inductive lighting surges.
