Surface Mount
Low Pass Filter
LPF-B35+
50Ω DC to 35 MHz The Big Deal
• Low Insertion loss
• High rejection
• Fast roll-off
• Miniature shielded package
CASE STYLE: HZ1198
Product Overview
The LPF-B35+ is a lowpass filter in a shielded package (size of 0.472" x 0.826" x .22") fabricated using SMT technology. Covering DC-35 MHz band width, these units offer good matching within the passband and high rejection. This
unit uses a miniature high Q capacitors and wire welded inductors for high reliability. In addition it has repeatable
performance across production lots and consistent performance across temperature.
