SIF Ceramic Filters
SIF Ceramic Filters
Type:
S
SIF Ceramic Filters have lower insertion loss and provide better spurious suppression characteristics, compared with conventional LC filters, because they use a worldwide patented “PCM” Piezo-electric material as a filter element, which features low resonant resistance and high stability against temperature changes.
■ Features
● ● ● ● Excellent frequency vs. attenuation characteristics Excellent spurious suppression characteristics Low insertion loss Contributes to circuit simplifi cation because it is adjustment-free ● RoHS compliant
■ Recommended Applications
● ● ● ● Bandpass filter for TVs SIF-stage Bandpass filter for VCRs SIF-stage Killer circuit for VCRs (PAL, SECAM) Recording/Reproducing circuit for VCRs (PAL, SECAM)
