Precision flat chip resistors KOA RK73H2ATTD1600F with thick film technology and EU RoHS compliance
EU RoHS Flat Chip Resistors
This product catalog contains specifications for rectangular chip resistors. Please confirm specifications before ordering and use. For applications involving automotive, medical, or aerospace equipment, or any situation where failure could lead to personal injury or significant loss, please contact us prior to use. Specifications are subject to change without prior notice.
Product Description
The RK73H series are precision grade thick film flat chip resistors. They are characterized by their small size, light weight, and excellent heat and weather resistance due to the use of metal glaze thick film. The triple-layer electrode structure ensures high stability and reliability. These resistors are compatible with automatic mounters for taping and bulk packaging, and are suitable for both flow and reflow soldering. The lead-free termination meets EU-RoHS requirements, with exemptions for lead glass in the electrode, resistor element, and glass. AEC-Q200 qualified data is available for most types (excluding 1F).
