B69812N2457C201
Features
• SMD filter consisting of coupled resonators with stepped impedances
• low losses
• high attenuations at GSM (900, 1800) and UMTS bands
• high attenuation a 2 times center frequency
• (NdBa)TiO3 (ε_r = 88 / TCf =0±10 ppm/K) with a coating of copper (10µm) and tin (>5µm)
• Excellent reflow solderability, no migration effect due to copper/tin metallization
