Derating Curves
Note: Thin film capacitors are not suitable for reflow soldering, as thermal shrinkage may cause performance issues.
Derating: If operating temperature exceeds the rated range (-40~70), derate rated voltage and permissible current as follows:
- +70 to +85: 1% per
- +85 to +105: 1.25% per
Estimated Lifetime
100,000 hours when |C/C|10% @UN and hs 70.
Storage Requirements
- Store in an environment with temperature 35 and humidity 70%RH.
- Avoid exposure to high temperatures and humidity.
- Product shelf life is 12 months from the date on the packaging or product body.
- Atmospheric conditions containing chlorides, sulfides, and sulfates can degrade the solderability of the leads.
