Data Sheet
ISSUE DATE 05.07.04 ISSUE P1 PUBLISHER SAW MWC PD PAGE 1/4
Features
zSMD filter consisting of coupled resonators with stepped impedances
zMgTiO3-CaTiO3 (εr = 21 / TCf =0±10 ppm/K) with a coating of copper (10µm) and tin (>5µm)
zExcellent reflow solderability, no migration effect due to copper/tin metallization
z ESD insensitivity and ESD protecting due to filter characteristics
