The 12 GHz frequency ceiling means it handles signals up to 12 GHz before the insertion loss climbs; for typical 75 Ohm applications like broadcast video or high-speed data, that's plenty of headroom. ## Mounting and Termination — What to Expect on the Board The end launch footprint is typically a cutout in the PCB edge with plated half-holes; the connector aligns to those half-holes and gets soldered. This is a common approach for RF modules where you want the coax interface at the board boundary without a long trace run. The snap-on fastening mates with a standard MCX plug — no threading, no bayonet, just push until it clicks.","metaTitle":"Amphenol RF 919-418J-71P12G MCX Jack, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 919-418J-71P12G MCX jack, female socket, 75 Ohm impedance, rated to 12 GHz.

The impedance is 75 Ohm, but the connector style is MCX — a smaller, snap-on interface. A BNC connector has a bayonet lock and a different shell diameter; this part will not mate with a BNC jack."},{"question":"What is the mounting type of 919-418J-71P12G?","answer":"Board edge, end launch. No through-hole or surface-mount pads — the signal path is at the board edge."},{"question":"Is the Amphenol RF 919-418J-71P12G RoHS compliant?","answer":"RoHS compliance is not explicitly stated in the available specifications.
