Characteristics  
Remark:  
Reference level for the relative attenuation a of the TFH 44C is the insertion loss. The insertion loss a is defined as the insertion loss at the  
rel  
C
e
nominal frequency f . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level  
N
relative to the insertion loss a . The temperature coefficient of frequency Tcf is valid for both the reference frequency f and the frequency response
