VF -Temperatur - Drift : It is determined within -40 bis +85 °C

40 dB
The tolerance range of the VF temperature drift is determined
by two parallel lines:
VFmax = VF (M1) + m (M + 60 dB+ 3dB)
VFmin = VF (M1) + m (M + 60 dB - 3dB)
The VF values for temperatures between -40 to +85 °C within
the VF dynamic range (MVFmin≤VF≤MVFmax) must be
inside the predetermined tolerance field:
VFmin≤ VF ( M ) ≤ VFmax
