[SOLVED] how to identify temperature coefficient of polypropylene capacitor??

[sgugan]

these are the information written on the polypropylene capacitor
_______________________
DEC/MER .033/J 250V E7
_______________________
.033 is 33nf
J for ±5%
250 is max voltage
what does "E7" stands for?, is it the identification of temperature coefficient?

another capacitor with
______________________
".022MF K 250V C1"
______________________
K is for ±10% tolerance
what does "C1" stands for?

How to identify the temperature coefficient?

are the all polypropylene capacitors have same temperature coefficient(-250ppm/°C)?

For manufacturer specific component marking review datasheets or part catalogs.

are the all polypropylene capacitors have same temperature coefficient(-250ppm/°C)?

Yes, see the datasheet curve for MKP/MFP
