Above 4 GHz the insertion loss climbs and the connector body starts to radiate; for sub-4 GHz work it is a clean, field-proven interface. ## Mounting and hardware This is a rear-side-nut bulkhead mount — the connector body passes through the panel from the front, and the included lockwasher and nut secure it from behind. The shield is terminated via a solder tag, and the centre contact uses a solder cup — both require hand soldering to the cable braid and centre conductor. The extended insulation feature (listed on the part) provides extra dielectric creepage between the centre pin and the body, useful when the cable jacket is stripped back further than usual. ## Mechanical and environmental The dielectric is PBT (polybutylene terephthalate), which holds up to the temperature extremes and resists moisture absorption.","metaTitle":"TE Connectivity 227755-1 BNC Jack, 50 Ohm, 4 GHz, Bulkhead","metaDescription":"TE 227755-1 BNC jack, female socket, 50 Ohm impedance, 4 GHz max, 500 mating cycles.
