/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-meter-shield-functional-testIntro This installment on my Super Capacitor Experimentation Project covers functional testing of the supercapacitor meter shield. The last blog covered assembly of the PCB. This blog shows the shield is able to charge and discharge with constant cu.en-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-meter-shield-functional-testThu, 07 Sep 2023 13:42:42 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a9afa4fd-930e-4f49-b545-004c43b0b8f6dang740<p>I like that you support an ESR test.&nbsp; The general assumption is that ceramic capacitors have a small ESR.&nbsp; Unfortunately, ESR is rarely ever reported in their datasheets.&nbsp; Every once in a while you will encounter regulators that impose an ESR range on their output capacitors.&nbsp; When you consider using a multilayer ceramic for this application you are kind of operating blind as far as ESR is concerned.... so yeah I like that your project measures ESR.</p><img src="https://community.element14.com/aggbug?PostID=26806&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/experimenting-with-supercapacitors/b/blog/posts/supercap-meter-shield-functional-testTue, 05 Sep 2023 18:48:12 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:a9afa4fd-930e-4f49-b545-004c43b0b8f6DAB0<p>Very good update Douglas.</p><img src="https://community.element14.com/aggbug?PostID=26806&AppID=419&AppType=Weblog&ContentType=0" width="1" height="1">
