21E7.5AD Datasheet, PDF (1/1 Pages) NIHON DEMPA KOGYO – crystal filter that supports surface mounting.

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.
