• Description: On-Board Type (DC) EMI Suppression Filters (EMIFIL)
• Manufacturer: MURATA [Murata Manufacturing Co., Ltd.]

!Note
!Note
The chip "EMIFIL" NFM21C 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.
1. Small and low profile of 2.0x1.25x0.85mm
2. 3-terminal structure enables high performance in
3. Uses original electrode structure which realizes
4. An electrostatic capacitance range of 22 to
1. PCs and peripherals which emit high amount of noises
2. Compact size equipment such as PDA, PC card and
3. Severe EMI suppression and high impedance circuits
