Product Overview
The RN73H series are high-reliability metal film flat chip resistors designed for demanding applications. They offer high precision with tight resistance tolerances (0.05%) and excellent temperature coefficient of resistance (T.C.R. 510-6/K). These resistors feature low current noise, a wide operating temperature range up to 155, and improved moisture resistance due to a special protective coating. They are suitable for control circuits in various industrial equipment and are compatible with both flow and reflow soldering processes. These products meet EU-RoHS requirements and are AEC-Q200 qualified.
