for output:
210 Ω -5,38 pF.

2. Characteristics
Remark:
Reference level for the relative attenuation a
of the TFS 420A is the minimum of the pass band attenuation a . The minimum of the pass
min
rel
band attenuation a
is defined as the insertion loss a . The nominal frequence fN is fixed at 420,0 MHz without tolerance or limit. The
e
min
c
reference frequence f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the
insertion loss a . The temperature coefficient of frequency Tcf is valid both for the reference frequency f and the frequency response of the
e
c
filter in the operating temperature range.

The minimum bending radius is 45 mm. The mounting surface of the filters faces the bottom side of the embossed carrier tape.
The marking of the filters is able to read if the view is directed on the upper side of the carrier tape with the sprocket holes on
the right side of the tape.
