Product Description
Product Overview
The RK73H series are high-reliability thick film flat chip resistors (precision grade) designed for various applications. They offer small size, light weight, excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures high stability and reliability. These resistors are suitable for automatic mounters and compatible with both flow and reflow soldering. They feature lead-free terminations and comply with EU-RoHS requirements. Some models are AEC-Q200 qualified.
