Product Description

The 45R12B with centre frequency of 45.0MHz packs four poles within just one miniature surface mount package measuring just 7.2 x 5.2mm. Advanced space-saving tehcnology means compared with traditional two-package four-pole filters ths 45R12B can offer the engineer much greater board space for their design. With passband bandwidth of 12kHz at 3dB, the 45R12B also has low insertion loss of only 3.0dB and has guarenteed attenuation of -90±10 @ 80dB. Low in-band ripple of only 1.0dB ensures high signal fidelity.
