Since capacitance is inversely proportional to frequency, given a fixed measurement time, the schemes naturally provide the highest bit resolution for the lowest capacitance values in a given range.

Therefore, for a 22-µF, 20%, X7R MLCC, the initial capacitance could be as low as 15 µF in the worst-case scenario [22 µF × 80% (low end of the tolerance) × 85% (assuming it retains 85% of ...

Figure 1: Showing parasitic capacitance from sides of metal and from top and bottom of metal. It should be noted that case 1 capacitance is always higher then case 2. Now let’s discuss some important ...

Murata begins mass production of the world's first 0805-inch size MLCC to offer a capacitance of 10µF with a 50Vdc rating for automotive applications.

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

My JYE Tech capacitance meter works almost as well as the one I remember from the shop. My no-name AVR-Transistor testor is almost as good of a capacitance meter as the JYE Tech!

Negative capacitance arises in ferroelectric materials, whose spontaneous electric polarization can be reoriented with the application of an external electric field. To create negative capacitance, an ...

Many techs shut systems down, discharge the capacitors, remove the leads, and test with capacitance testers on their multimeters. There are situations when this makes sense, such as when the system is ...
