  • High rejection, 60 dB typ.
  • FM radio rejection (88 to 108 MHz)
  • Miniature shielded package Product Overview The BSF-108+ is an SMT stopband filter, designed to reject FM radio broadcasts from 88 to 108 MHz. With over 20 dB rejection at stop band, low insertion loss at passband and good input and output return loss. The BSF-108+ has good repeatability across production lots, consistent performance over temperature and is cased in a metal case (size of 0.44" x 0.74" x 0.27"). Feature Advantages High rejection, 60 dB typical Reduces the effect of harmonics and unwanted signals FM radio rejection The BSF-108+ is highly suited for applications where interference from FM radio transmis - sions is a concern. Shielded case Reduced interference with the surrounding components. Small size, 0.44" x 0.74" x 0.27" The small surface mount package enables the BSF-108+ to be used in compact designs Key Features Band Stop Filter BSF-108+ 50Ω 88 to 108 MHz Page 1 of 2 CASE STYLE: HF1139
