Characteristics  
Remark: Reference level for the relative attenuation a  
of the TFS 125H is the minimum of the pass band attenuation. Reference for the echo  
rel  
response attenuation is the main time response lobe, the reference time is defined as t0. The nominal frequency f is fixed at 125 MHz without  
N
tolerance. The given values for the relative attenuation a and for the group delay ripple have to be reached at the frequencies given below even  
rel  
if the centre frequency f is shifted due to the temperature coefficient of frequency TC in the operating temperature range and due to a  
c
f
production tolerance for the centre frequency f .
