12 V vehicles don’t require special disturbing pulse reductions.
NOTE
The values above are not including the power dissipation of the microcontrol-
ler EMU RAM part.
NOTE
The FETK-T3.0 will accept permanent power supply voltage dips (for addi-
tional details of 3 V low voltage operation, see ISO standard 16750).
