EPCOS B69812N2457D201

Microwave Ceramics and Modules
2 – Pole Filter for W - LAN
Filter
B69812N2457D201
Data Sheet
Features
• SMD filter consisting of coupled resonators with stepped impedances
• extreme low losses
• high attenuations at GSM (900, 1800) and UMTS bands
• high attenuation at 2 times center frequency
• (NdBa)TiO3 (εr = 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
