It's a single-port, snap-on coupled connector rated to 4 GHz with 0.3 dB insertion loss — a standard choice for RF interconnects where quick disconnect and moderate frequency range are needed.
RF Performance and Mechanical Fit
The 50 Ohm impedance and 4 GHz maximum frequency put this in the range for GPS, ISM-band radios, and short-run data links — not a high-frequency microwave interconnect, but solid for sub-4 GHz work. The 0.3 dB insertion loss is typical for an SMB interface at these frequencies. Snap-on coupling means quick field mating without tools, but the retention is less positive than a threaded SMA — the 500-cycle rating is a practical limit for repeated connect-disconnect in test or field-service scenarios.
The voltage rating is 335 V.
Comparison with 415218-1
The 415218-1 is also an SMB receptacle in Bulk package with Active lifecycle — same connector style and basic form factor. The difference is in the center contact material and plating details; the 413990-1 uses gold-plated brass center contact, while the 415218-1 may differ. For a form-fit-function cross, verify the center contact spec against your application before substituting.
