When used below the specified operating temperature range, the main concerns are capacitance variation, reliability, and resistance to temperature cycling.
For example, both B-type and F-type products have an operating temperature range of -25 to 85°C. Within this range, the capacitance change is specified as ±10% for B-type and +30% to -80% for F-type.
However, these specifications may not be maintained outside the operating range.
In terms of reliability, ceramic capacitors generally degrade more rapidly at higher temperatures due to their temperature-dependent characteristics.
Operation below the specified temperature range does not typically reduce reliability, but care should be taken to prevent condensation.
In addition, resistance to temperature cycling decreases as the operating temperature range widens.
Please use caution in environments where temperatures repeatedly fluctuate between the maximum and minimum limits.
Note: Use outside the specified temperature range is not covered by the warranty.
