Crystal Filter  
(Surface-mount Type)  
2 Pole MCF  
Features  
n
This is a crystal filter that supports surface mounting. Adoption of a ceramic container  
has enabled the dimensions of the filter to be 7 ꢀ 5 ꢀ 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 Eꢀcellent 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.
