2024-05-11 New Capacitor With 19 Times Power Density Could Help EV Batteries Last Longer

It looks like this supercapacitor could quickly charge and discharge, thus reducing the cycles on the EV battery. https://www.livescience.com/technology/electronics/ev-batteries-could-last-much-longer-thanks-to-new-capacitor-with-19-times-power-density-that-scientists-created-by-mistake

2024-03-24 Signal Distortion From High-K Ceramic Capacitors

A good article about signal distortion in a Butterworth low pass opamp filter using C0G and X7R MLCCs.  https://www.edn.com/signal-distortion-from-high-k-ceramic-capacitors/

2023-12-05 1500 pF Capacitors “Age Down” In Value – Out Of Tolerance?

James Chessman gave me permission to use his comment. “””I have encountered a phenomenon called “age-down” in ceramic capacitors tested on ICT (In-Circuit Test) machines. I was working for a circuit-board manufacturer, developing new test sets. I was seeing these caps consistently read high in new tests. And, pulling them out of the circuit they
