NFM21C Series

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.

s Features

1. Small and low profile of 2.0x1.25x0.85mm

(NFM21C) enables high density mounting.

2. 3-terminal structure enables high performance in

high frequency range.

3. Uses original electrode structure which realizes

excellent solderability.

4. An electrostatic capacitance range of 22 to

22000pF enables suppression of noise at specific

frequencies.

s Applications

1. PCs and peripherals which emit high amount of noises

2. Compact size equipment such as PDA, PC card and

mobile telecommunications equipment

3. Severe EMI suppression and high impedance circuits

such as digital circuits
