It can reduce residual inductance to an extremely low level making it excellent for noise suppression at high frequencies. 0.60.2 2.00.2 1.250.1 s Features 1. Small and low profile of 2.0x1.25x0.85mm (NFM21C) enables high density mounting. 2. Three 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.
