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