SMA F 4H Panel Mount RA Solder

Description

The SMA Female 4-Hole Panel Mount Right-Angle Connector is a heavy-duty RF component engineered for mounting onto chassis walls, shielded enclosures, and bulkhead panels. The 4-hole square flange (typically 12.7mm / 0.5″) provides a rock-solid mechanical anchor, distributing the physical stress of external cables across four mounting points to prevent rotation, loosening, or displacement.

Optimized for High-Density RF Packaging

The defining advantage of this model is its Right-Angle (90?) solder terminal. This configuration is essential for compact enclosures where internal space is at a premium. Instead of the signal wire protruding straight into the housing, it exits parallel to the panel, allowing for cleaner cable management and a lower overall device profile. This makes it a top choice for military communication gear, satellite ground equipment, and precision test fixtures.

Key Technical Advantages:

• 4-Hole Square Flange: Ensures maximum mechanical durability and a high-strength bond to the panel, protecting delicate internal solder joints from external torque.

• Right-Angle (90?) Solder Terminal: Facilitates low-profile internal routing, making it ideal for shallow enclosures or space-constrained microwave modules.

• Superior Grounding & Shielding: The large surface area of the square flange creates an excellent electrical connection with the metal chassis, significantly reducing EMI and signal leakage.

• Low VSWR Performance: Precision-machined to maintain a stable 50 Ohm impedance across the DC to 18 GHz range, ensuring minimal insertion loss and maximum signal integrity.

• Premium Construction: Features high-purity gold plating on a brass body with a gold-plated beryllium copper center contact for lifelong corrosion resistance and excellent solderability.
