Product Description
Product Overview
The RN73H series are high-reliability metal film flat chip resistors designed for demanding applications. They offer high precision resistance tolerance (0.05%) and temperature coefficient (510-6/K), low current noise, and an extended operating temperature range up to 155. Featuring a special protective coating for improved moisture resistance, these resistors are suitable for control circuits in various industrial equipment and are compatible with both flow and reflow soldering. They meet EU-RoHS requirements and are AEC-Q200 qualified.
