Product Overview
The RN73H1JTTD1912F100 is a precision chip resistor array from KOA Speer Electronics. It contains four independent 1.91kΩ resistors (1912 = 191 × 10^1 = 1910Ω) with ±1% tolerance in a 16-pin SOP/0804 package. The RN73H series features high stability thin film technology with ±25 ppm/°C temperature coefficient, making it suitable for precision analog circuits, voltage dividers, and signal conditioning applications.
The ‘F’ indicates ±1% tolerance and ‘100’ denotes the packaging code. These resistor networks provide matched tracking between resistors and save significant PCB space compared to discrete resistor implementations.
