Product details

The 3FA1-NASJ-C01W0: It belongs to the 3FA1-NASJ base series and carries Code A keying, which prevents cross-mating with other Fakra code variants in multi-connector harnesses. The connector handles signals up to 3 GHz, making it suitable for automotive antenna feeds, telematics modules, and short-reach RF interconnects where the SMB snap-on coupling is preferred over a threaded interface.

Cable compatibility and crimp termination

This jack accepts RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables. The zinc die-cast body with tin finish provides a durable ground path and resists corrosion in under-hood or exterior-mounted positions.

Impedance and frequency ceiling

The 50 Ohm impedance matches the standard RF system impedance. The 3 GHz maximum frequency covers GPS /L2, cellular bands, and ISM bands.
