Escribe Battery Curves, TFR / TCR Curves and Mod Thermals Downloads Curves are in baby!! That’s right. Our awesome downloads section just got even more awesome. We’ve created three brand new sections which are going to be fantastically useful. You’ll now find dedicated areas for TCR/ TFR Curves, Mod Thermals and Battery Discharge Curve CSVs. […]
What is TCR or Temperature Coefficient of Resistance?
Every wire material has a specific resistivity. As a wire heats up, its resistance will increase in a predictable way based on its TCR.
TCR for a material is usually measured by the wire manufacturer using MIL-STD-202 Method 304, which uses a series of test temperatures. The first series is 25°, 0°, -15°, and -55°C; the second series are 25°, 50°,75°, 100°, 125°, 200°, 275°, and 350°C. The lowest test temperature in the first series, and the highest test temperature in the second series, are used as two points to create a linear TCR value.
