Welwyn / TT Electronics LRMAP4026 AEC-Q200 Low Resistance Power Resistors
Welwyn / TT Electronics LRMAP4026 AEC-Q200 Low Resistance Power Resistors are metal alloy resistors featuring four-terminal, Kelvin gullwing terminations in a compact 4026 package size. The gullwing design provides spacing from the PCB minimizing the board temperature rise and enhancing the reliability of the assembly. With 1% tolerance and 50ppm/°C, the LRMAP4026 shunt resistors combine good precision with the high surge capacity of metal alloy technology. These resistors are available in seven values ranging from 0.2mΩ to 3mΩ and operate within a wide -65°C to +170°C temperature range. High surge tolerances assure reliable performance under inrush and momentary short circuit conditions. The Welwyn / TT Electronics LRMAP4026 AEC-Q200 Power Resistors are ideal for industrial and automotive applications but are specifically designed for power supplies, motor drives, and battery monitoring.
