A high ESR reading may reveal damaged cells or a bad internal connection. All tests are instant and require no other equipment. Checking and matching new cells is another application; the table of typical readings for good cells will help get you started, until you create your own database....
I was talking about pole and zero locations in which ~50mOhms does shift by an incredibly small amount, and is within the acceptable range, but ceramic capacitors are almost always better especially for newer devices. I assumed we were talking about non ceramics...

There is a table "typical ESR value of electrolytic capacitor" at the back, it is for guiding only, these are typical value for standard grade electrolytic capacitor at room temperature. Calibration: Short the test pin 1, 2, 3 together and push "POWER / TEST" button, then the screen prom...
The outlook of this meter is fantastic, perfect finishing, clean, and clear display four digits. You will get the ESR parameter table on the body of this excellent meter. There are zero buttons for manual zeroing the meter on the left power button and right-side mode range. You will get...
Temperature performance: See table 1. Climatic category: 55/125/21. Life test: 2000 hours. Reliability: 2% per 1000h at 85C with 0.1Ω /V series impedance 60% confidence level. As a result of the different construction and requirements for tantalum SMT capacitors, the...
The EIA & CECC standards for low ESR Solid Tantalum Capacitors allow an ESR movement to 1.25 times catalogue limit post mounting. For typical weight and composition see page 274. NOTE: AVX reserves the right to supply higher voltage ratings or tighter tolerance part in the same case size, ...
To select output capacitors for a DC/DC switching regulator application, the basic parameters you must pay attention to include capacitance, equivalent series resistance (ESR), rated voltage, and size. Table 1 compares the four types of capacitors. Multi-layer Ceramic Capacitor Aluminum Electrolytic ...
