!Note
!Note
The chip "EMIFIL" NFM3DC series is a chip type
3-terminal EMI suppression filter. It can reduce
residual inductance to an extremely low level making
it excellent for noise suppression at high frequencies.
An electrostatic capacitance range of 22 to 22,000pF
enables suppression of noise at specific frequencies.
High noise radiation and high impedance circuits such
as digital circuits
