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.
