6 FAQs about [Which capacitors can withstand low temperatures]
What is a low temperature capacitor?
When operating at the low-temperature limit, the capacitance of aluminum electrolytic capacitors with a low temperature rating of -550C declines by less than 20%. The resistive component of an equivalent series circuit of a capacitor is referred to as the equivalent series resistance (ESR).
Are aluminum electrolytic capacitors stable at low temperatures?
For aluminum electrolytic capacitors, this functional parameter is usually stable at low temperatures. In addition, the initial leakage current of an aluminum electrolytic capacitor is dependent on storage duration and conditions. The impedance of an aluminum electrolytic capacitor is dependent on frequency and temperature.
What is the capacitance loss of a low voltage capacitor?
When operating at -400C, low-voltage aluminum electrolytic capacitors with a low temperature rating of -550C exhibit a capacitance loss of between -10% and -20%. Capacitance loss for high-voltage capacitors can be up to 40%.
What type of capacitor should I buy?
C0G ceramics are the best for this applications. Very Low temperature drift and commonly available to 5% and less commonly to 2%. No need to buy expensive Polyester, Polypropylene, or PET capacitors. Those are for intense high-power pulse applications. The above comments should help. WHit3rd...Given the age, C1 & C2 could be mica.
What determines a high-temperature limit of an electrolytic capacitor?
Largely the formation voltage sets the high-temperature limit. Higher formation voltages permit higher operating temperatures but reduce the capacitance. The low-temperature limit of an electrolytic capacitor is set largely by the cold resistivity of the electrolyte.
Do electrolytic capacitors have a minimum temperature rating?
To be honest I have never seen an electrolytic capacitor with a minimum temperature rating. They and most capacitors DO have a maximum temperature rating. Most are rated to 85 C but for SMPS and other power devices you may need to buy 105 C rated versions. An 85 C capacitor exposed to 100 C will have a short life.
