Most filter attenuation curves and capacitance values are
expressed at 25° C. However, temperature can affect the
capacitance of a titanate filter element, affecting the insertion
loss that the element will cause.
In order to assist the user in anticipating the effect of various
temperatures, the following charts applicable to Amphenol
ter connectors utilizing MF-1, HF-1, VHF-1, VHF-2, UHF-1 and
UHF-2 filters are provided. Please note that all insertion loss
(attenuation) values given were measured with no load applied.
The band designations refer to MIL-STD-2120.
