Crystal Filter
2 Pole MCF
(Surface-mount Type)
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.
● Supports IR reflow and VSP.
(Contact us for information on the temperature profile.)
● Supports surface mounting. (Packed with embossed tape)
● Excellent heat- and shock-resistance.
● Good guaranteed attenuation.
● Frequency range Fundamental: 20 to 90 MHz, Overtone: 60 to 150 MHz
● Also supports 3-pole MCF.
