744C043000XP

744C043000XP Description

The 744C043000XP from CTS Resistor Products is a specialized 2-resistor array designed for high-density PCB applications requiring zero-ohm jumpers. Housed in a compact 1210 (3225 Metric) concave package, it features a 0.0-ohm resistance with a jumper tolerance, making it ideal for short-circuiting or bridging traces. The device operates within a ±200ppm/°C temperature coefficient and delivers 125mW power per element, ensuring reliable performance in demanding environments. Its surface-mount design (0.126" x 0.100") and 0.028" (0.70mm) low profile enable efficient space utilization. Although marked as obsolete, it remains ROHS3 compliant and REACH unaffected, adhering to environmental standards.
