Bel Fuse-RF Adapters - Between Series Adapter Assembly 1.85mm Male / SMP3 Male
16 January 2023
Bel Fuse introduces the new SMP3 family of connectors.
miniature push-on style
connectors. It follows the prior generation SMPM and SMP connectors. SMP3 is more miniaturized (approximately 30% smaller than SMPM)
and operates to 67 GHz by design. It is ideal for applications where there is high shock and vibration. The design is similar to SMPM and SMP
for its utilization of a floating bullet. This helps compensate for axial and radial misalignment when mating. This also helps maintain a high
performance retention in rugged military applications.
The sub-miniature, push-on connector interface is known for its blind mate capability. The smaller profile allows design engineers to fit the
interconnects into dense packaging area.
