Selecting the right capacitor for smart meter applications is important. Not all X2 capacitors are created equally, here's something that makes the F862 different.
Selecting the right capacitor is a matter of understanding the materials used to construct them. This post provides an overview of different capacitor materials (and not just dielectrics!)
Calculating the combined impedance of a decoupling network can be tricky. KEMET provides a tool called K-SIM that provides engineers a simple way to determine capacitor decoupling impedance.
When looking for detail information about parameters like ESR and Impedance, you might be surprised manufacturers don't include EVERYTHING in the datasheets. Sometimes parameters are specified at frequencies or temperatures that do not match your application. Other times, like in the case of ceramic capacitors, specs like ESR might be missing entirely. This post shows how to find that information for KEMET capacitors.
Choosing the correct current-sensing technique for your smart meter design is critical. Although several current-sensing techniques are available, the current transformer is ideal when accuracy, energy efficiency, reliability, and ease of use are as important as an economical price.
