Crystal Filter
2 Pole MCF
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.
