Document 156 Surface Mount Tip and Ring Filters These surface mount tip and ring filters provide substantial reduction of noise throughout an extended frequency range. They’re packaged in a flat-top ceramic header for reliable pick and place operations and optimal thermal characteristics. Parts are manufactured with lead-free solder that make them compliant with RoHS standards.
