SMA F BH for PCB solder with stand off

Description

The SMA Female Bulkhead PCB Solder Connector with Standoff is a hybrid RF solution engineered for high-durability electronic assemblies. By combining a Bulkhead (BH) threaded housing with Integrated Standoffs on the PCB mounting base, this connector offers the ultimate in structural stability and electrical performance.

The “Double-Anchor” Advantage

In rugged applications, external antennas or heavy cables can put immense strain on a PCB. This connector solves that problem: the bulkhead nut secures the connector to the device’s metal or plastic chassis, while the 4-leg standoff base is soldered into the PCB. This design transfers all external torque and pulling forces to the enclosure rather than the delicate solder joints.

Key Technical Advantages:

• Integrated Standoffs: Built-in spacers elevate the connector body above the PCB, allowing for thorough flux cleaning, easy solder joint inspection, and improved heat dissipation during operation.

• Bulkhead Chassis Grounding: The threaded barrel passes through the panel, providing a direct electrical ground to the enclosure, which significantly improves EMI/RFI shielding.

• Superior Mechanical Stability: The standoff legs provide a rock-solid foundation, ensuring the connector remains perfectly vertical during assembly and service.

• Low VSWR Performance: Optimized for DC to 6 GHz (and up to 12 GHz depending on board layout), making it ideal for Wi-Fi 6, LTE, and Sub-6GHz 5G applications.

• Premium Gold Plating: High-grade gold finish ensures maximum conductivity and prevents oxidation, maintaining a reliable 50 Ohm connection over 500+ mating cycles.
