Fort Technology's High Power Current Sensing Resistors are designed for applications requiring precise current sensing, voltage division, and pulse handling. These resistors feature a stable alloy material with ultra-low TCR (50ppm/C), enabling high temperature derating up to +170C. They are suitable for high-precision current sensing and circuit protection, offering excellent stability with a low resistance change over time. The pure tin plating ensures compatibility with both lead-free and lead-containing soldering processes. Constructed with high-grade materials and protected by a robust coating, these resistors meet RoHS directive 2011/65/EU, are Halogen-free, and utilize flame-retardant material compliant with UL94 V-0 requirements.
