which capacitor type should be used for Low Temperature efficeincy

[malik_123]

I am to make an equipment which could work as low as -25 C.

which type of capacitor should i use.

I am using Max232 and electrolyte capacitor.

can electoryltic capacitor be used for low temperature as i read in wiki

": for most types, capacitance falls off rapidly below room temperature while dissipation factor can be ten times higher at −25 °C than at 25 °C. Most limitations can be traced to the electrolyte."

wht could be a good choice.

what about tantalum ?

please need an immediate response

mailk,

There are several classes in EIA standard.
Buy somethik like X7R, most common at industrial applications.

EIA Class 2 dielectric - Wikipedia, the free encyclopedia

Sorry, you meant electrolitic capacitors.

Try that :
