1. Ultra small size in 1.6x0.8x0.6mm enable high
density mounting.
2. 3-terminal structure with low residual inductance
(ESL)* characteristics achieves large insertion
loss characteristics even in high frequency area.
3. The NFM18cc series covers capacitance range from
22 to 22000pF.
* Not exceeding one-tenth of monolithic ceramic
capacitors (2-terminal).
