| Description & Applications | On-Board Type (DC) EMI Suppression Filters (EMIFIL) Chip EMIFIL Capacitor Type NFM18C/NFM21C/NFM3DC/NFM41C Series 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. 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. Applications 1. Compact size equipment such as PDA, PC card and mobile telecommunications equipment 2. Severe EMI suppression and high impedance circuits such as digital circuits |
