RS73 High Reliability Chip Resistors
The RS73 series offers high reliability chip resistors designed for surface mounting. These metal-glaze thick film resistors provide high precision with excellent temperature coefficient of resistance (T.C.R.) and tight tolerances. They are suitable for both flow and reflow solderings and meet EU RoHS requirements for lead-free terminations. The RS73 series is AEC-Q200 tested, making them ideal for demanding applications.
