The ASC series anti-sulfur chip resistors are specially designed to resist sulphide growth and withstand sulphur-bearing fumes. They are suitable for industrial, automotive, and roadside applications, tested to ASTM-B809 standards. These resistors feature ROHS-compliant matt tin finish terminations, are AEC-Q200 qualified, and are available in multiple sizes including 0402, 0603, 0805, 1206, 1210, 2010, and 2512. They handle power ratings up to 1W at 70°C, with resistance ranges from 1 ohm to 10 megaohms. Rugged and reliable, they offer TCR below 200 ppm/°C for most sizes, with low resistance tolerance of 1% and operating temperature from -55°C to +155°C. Their construction includes resistive elements on alumina substrates with wrap-around solderable terminations, plated with nickel and matt tin. Markings are size-appropriate and resistant to cleaning solvents, ensuring durability in harsh environments. These resistors meet strict industry standards, delivering stable performance in demanding conditions.
