RS73 High-Precision Flat Chip Resistors

KOA Speer RS73 High-Precision Flat Chip Resistors are high-precision devices with resistance change of ±0.2% and ±0.5%. KOA Speer RS73 metal glaze thick film resistors also feature a low temperature coefficient of resistance (TCR) of ±25ppm/°C and ±50ppm/°C and a resistance range of 10Ω to 10MΩ. RS73 resistors are AEC-Q200 qualified and come in 0603, 0805, and 1206 case sizes. The series is ideal for use in automotive, measuring equipment, and industrial measurement applications.
