I have some fairly short leads on a piezo that appear from resonance measurements to have an inductance of 20uH or so. Is this typical? I mean the leads are in length about 20cm or 8 inches in total and multicore of 1mm diameter. They travel through a breadboard too. It may be that the LCR meter I'm using isn't so accurate.
On LCRs, I had 20 individual parts sent with individually measured capacitances. For example the datasheet says Part 1: Capacitance 683nF. Part 2: Capacitance 692nF. However I measure the values with my fairly cheap LCR meter much lower typically 50-100nF lower. THe LCR meter is a Tenma 72-8155 model that cost around £30 or $50. I presume the answer is get a better LCR meter?
