Crystal Filter 2 Pole MCF (Surface-mount Type) n Features This is a crystal filter that supports surface mounting. Adoption of a ceramic container has enabled the dimensions of the filter to be 7 x 5 x 1.35 mm. Supports a wide frequency range. l Supports IR reflow and VSP. (Contact us for information on the temperature profile.) l Supports surface mounting. (Packed with embossed tape) l Excellent heat- and shock-resistance. l Good guaranteed attenuation. l Frequency range Fundamental: 20 to 100 MHz, Overtone: 45 to 150 MHz l Also supports 3-pole MCF.
