Product details

75 Ohm Right-Angle SMB Plug for RG-179 Coax

The Samtec TRUE75™ SMB7H-P-C-HF-RA-CA3 is a 75 Ohm SMB plug with a right-angle, free-hanging body, designed for RG-179 cable. The 75 Ohm impedance sets it apart from standard 50 Ohm SMB connectors — this one is built for video distribution, broadcast, and baseband telecom where the characteristic impedance of the coax path must be maintained.

This plug is sized for RG-179 coax — the cable group is specified in the part number. The right-angle body lets the cable exit perpendicular to the mating axis, which helps when routing coax in a shallow enclosure or against a backplane.

Signal Performance and Limits

Rated to 4 GHz maximum frequency, this plug covers standard-definition video, HD-SDI, and most baseband telecom signals through the L-band. Gold plating on both the body and centre contact resists corrosion and maintains a low, stable contact resistance over repeated mate cycles.

Frequently asked questions

Where can I buy SMB7H-P-C-HF-RA-CA3?

SMB7H-P-C-HF-RA-CA3 is available to order. Submit an RFQ for current pricing and lead time — availability is confirmed at quote time through independent distribution.

What is the impedance of SMB7H-P-C-HF-RA-CA3?

The SMB7H-P-C-HF-RA-CA3 is a 75 Ohm connector. This is a 75 Ohm SMB plug, not the more common 50 Ohm version, so it must be paired with a 75 Ohm jack and 75 Ohm cable to maintain the correct characteristic impedance.

What cable group does SMB7H-P-C-HF-RA-CA3 accept?

The SMB7H-P-C-HF-RA-CA3 is designed for RG-179 cable. The centre contact is soldered, and the shield is crimped with the included ferrule.
