BF44A2D

1. SCOPE The SAW filter series have broad line up products meeting all broadcast standard including NTSC, PAL and SECAM systems. These filters are composed of two interdigital transducers on a single-crystal. piezoelectrical chip. They are used in electronic equipments such as TV and so on. 2.Construction 2.1 Dimension and materials Type: BF44A2D 4 5 14.5 0.54 2.54 3.5 5.8 HD 1.25 3.8 1 2 3 Pin configuration 1 Input 2 Input-ground 3 Chip carrier-ground 4 Output 5 Output 2.2.
