capacitor derating


I am trying to study the effect of temperature on a set of capacitor (the parameter being voltage). In other words , I am looking at how the voltage rating of a capacitor is aeffected with variations in temperature. For eg - consider the derating curve of a capacitor shown in the image. As can be seen, as the temperature increases the voltage rating dips. enter image description here


I assumed that all capacitor datasheets must have sucha document. I am now refering the datasheet - http://www.avx.com/docs/Catalogs/cx7r.pdf They have not specified any info whatsoever. Can anyone guide me on how to fuind this info please ?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
