Moisture resistance of aluminum electrolytic capacitors
If planning for long-term use in a high-temperature, high-humidity environment, then please consider the use of a resin coat (note) or other moisture prevention measures.
As moisture resistance for our aluminum electrolytic capacitors, we guarantee compliance with the content outlined in Japanese Industrial Standards (JIS).
(Conditions will vary for conductive polymer aluminum solid capacitors and conductive polymer hybrid aluminum electrolytic capacitors. See the following table for details.)
Aluminum Electrolytic Capacitors: (JIS C 5101-1 4.22 compliant)
Series | Test parameters |
---|---|
all series | 40℃ at 90 to 95%RH: Left for 240 hours with no voltage applied |
Conductive Polymer Aluminum Solid Capacitors:
Products compatible with 85℃ at 85%:
Please note that there is a high possibility of a malfunction in extreme environments of high heat and humidity (100℃ and above with high humidity), such as the environment created during a pressure cooker test (PC test). As such, these products are not compatible with such uses.
