These are the primary positive and negative poles that carry the high current needed to drive heavy-duty motors.
This paper presents the complete electrical and thermal characterization of the , a bulk metal foil precision resistor rated for medium-voltage (MV) applications. Using an R-diagram (resistance versus operating parameters), we analyze its stability under variable temperature, load, and frequency. The device exhibits a nominal resistance of 210 Ω at 25°C, with a temperature coefficient of resistance (TCR) of ±5 ppm/°C over -40°C to +125°C. The R-diagram reveals three distinct operational zones: ohmic stability, thermal derating, and voltage-induced nonlinearity. Our results confirm that the PBM27A-210-MV-R maintains <0.1% drift after 2000 hours of continuous operation at 70% rated power, making it suitable for precision industrial and automotive systems. pbm27a-210-mv--r diagram
