Capacitance is a component parameter that can be crucial for circuit design, whether it is in a low frequency or high-frequency application. Protection devices and capacitors have an expected and desired capacitance that may be important for signal integrity or general circuit operation. Based on the frequency, temperature, and DC bias applied to the DUT, the capacitance may be much different than expected. ESDEMC’s LCR capacitance measurements allow for capacitance measurements to be taken at a specific DC bias level and temperature. The capacitance can be measured at frequencies lower than the VNA measurement method can achieve. The typical measurement frequencies are taken at 1 MHz – 10 MHz.
