This SMB jack is for moderate-frequency RF paths where 50 Ohm impedance is non-negotiable
The 415340-1: The snap-on coupling gives quick connect/disconnect, but the trade-off is the 0.6 dB insertion loss at the top end — fine for moderate-frequency signal paths but not for low-loss critical links at the band edge.
The 4 GHz maximum frequency covers sub-6 GHz bands like 2.4 GHz Wi-Fi, ISM, and cellular, but it does not reach into the 6-18 GHz range where SMA or SMPM connectors are needed. The 0.6 dB insertion loss at 4 GHz is a pass-through spec — at lower frequencies the loss drops, so for a 900 MHz or 2.4 GHz link the margin is better than the headline number suggests. The 335 V voltage rating is the breakdown limit across the PTFE dielectric; in practice the RF power handling is limited by the centre pin current capacity, not the voltage standoff.
Right-angle through-hole mounting — board layout implications
This is the right choice when the enclosure height budget is tight or when the cable needs to route flat against the chassis.
500 mating cycles — what that means for field service
Five hundred mate/demate cycles is the rated reconnect life for this snap-on RF connector. The gold-on-gold contact interface resists fretting corrosion through repeated connects.
