We are evaluating MIC21LV32 from microchip in one of our applications. For the current sensing we have used 3 mΩ sense resistor (1206, 1 %, 1 W), as these sense resistors have higher ESL+ parasitic inductance in PCB. During testing with R1=R3=100 Ω,…

Usually it is said that small SMD capacitors (e.g. 0603) have lower ESL than larger ones (e.g. 1206). This older question addresses the same problem and the answers confirm what I was thinking, namely that the ESL is determined by the current loop…

I have a divider circuit similar to a x10 scope probe. I need a bandwidth of least 100MHz, preferably greater. I am using through-hole MICA capacitors (1%). The capacitors have a low enough ESL that they should be adequate. While laying out the…
