High-power sense resistors feature high temperature stability
For current sensing applications requiring high efficiency, low resistance values are required. Typically, high power sense resistors are very large and have TCR in the 200 to 400 ppm range. Stackpole’s HCSM2818 is rated at 5 watts and now provides a 2 milliohm resistance value with a TCR of 100 ppm. This ensures the HCSM2818 is stable at […]
Tester evaluates internal battery electrochemical and electrical properties
The BA8100 is designed to test batteries using a complex AC measurement technique known as electrochemical impedance spectroscopy (EIS). Through this technique, the BA8100 derives the internal impedance of a battery across a wide frequency sweep. The acquired data is used to display a graphical representation of electrochemical processes occurring within the battery. The BA8100 […]
