Product Description
Product Overview
The ASC_WT04X_V14 is a series of chip resistors with a convex termination type, available in the 1206 size. These resistors are designed for high reliability and reduced equipment size, offering lower assembly costs. They are RoHS compliant and lead-free, making them suitable for consumer electrical equipment and EDP/computer applications. The construction involves a ceramic body with a resistive paste layer trimmed by laser, protected by a coating, and finished with tin-plated end terminations for ease of soldering.
