Product Overview
The ASC_WA04/06 series offers general-purpose chip resistor arrays designed for surface mounting. These resistors are constructed with a high-grade ceramic body and feature internal metal electrodes connected by a resistive paste, precisely trimmed by laser. They are available in convex and concave types, with various configurations like 4p2R, 8p4R, and 16p8R. Key advantages include small size, light weight, reduced equipment size, lower assembly costs, and enhanced component reliability. These products are RoHS compliant and lead-free. Applications span consumer electronics, EDP, and telecommunications.
