Most filter attenuation curves and capacitance values are
expressed at 25°C. However, temperature can affect the capaci-
tance 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 tem-
peratures, the following charts applicable to Amphenol
nectors utilizing MF
provided. Please note that all insertion loss (attenuation) values
given were measured with no load applied. The band designations
refer to MIL-STD-2120.
