Our rankings are cleverly generated from the algorithmic analysis of thousands of customer reviews about products, brands, merchant’s customer service levels, popularity trends, and more. The rankings reflect our opinion and should be a good starting point for shopping. By purchasing the products we rank, you’ll get the lowest price we found while we may receive a commission at no cost to you, which will help us continue to provide you with value.
[Support circuit test]: Our ESR meter only applies less than 15V of DC or peak-to-peak on a good capacitor, so we can use it as a circuit test.
[MESR-100 V2 auto-ranging capacitor ESR]: It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).
[Impedance Become Small]: We can then measure the true series resistor value.Fast and easy, inspect general capacitor or resistor, a printed ESR table for the fast check.
The impedance become small, and we can then measure the true series resistor value.
Our ESR meter only applies less than 15mV DC or peak to peak on a good capacitor, as a result we can use it as in circuit test.
It is a series resistor inside capacitor, using 100kHz to remove the impedance 1/(2*pi*F*C).

How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
Using this theory, we can measure the capacitor is bad/ damaged or good in condition.
