SMA Female Straight PCB Connector

PCB-mounted RF connectors must provide robust electrical performance and mechanical integrity under operational stress. Our SMA Female Straight PCB Connectors feature precision-aligned solder posts, reducing PCB via inductance and maintaining controlled impedance transitions. The connector body is manufactured from high-strength brass or stainless steel, mitigating structural deformation during high-vibration conditions. This ensures reliable grounding and consistent RF performance, even in high-speed digital and RF circuits where electromagnetic interference (EMI) suppression is critical. 

Performance degradation due to thermal expansion and environmental exposure is a major concern in mission-critical RF applications. Our SMA connectors operate within a wide temperature range of -65°C to +165°C, making them suitable for high-power RF transmission, aerospace systems, and defense applications. The gold-plated contact surfaces (2µm thickness) provide superior oxidation resistance, preventing signal degradation in humid or corrosive environments. The stainless steel coupling nut with a precise 1/4-36 UNF thread also ensures secure mating torque, minimizing micro-movements that can cause intermodulation distortion.
