SMA F 4H Panel Mount Solder

Description

The SMA Female 4-Hole Panel Mount Connector is a precision RF interface engineered for installations requiring maximum mechanical stability. Unlike single-nut bulkhead connectors, the 4-hole square flange allows the connector to be bolted directly to a chassis or panel using four screws. This design prevents rotation and movement, even when subjected to the high torque of frequent antenna or cable mating.

This connector features a solder-cup or tab terminal, making it ideal for custom internal wiring. It is widely used in RF shielding boxes, wireless base stations, and laboratory instruments where maintaining a consistent ground and low signal loss is critical. The robust construction and gold-plated finish ensure superior conductivity and long-term protection against environmental oxidation across frequencies up to 18 GHz.

Key Technical Advantages

• Enhanced Mechanical Stability: The 4-hole flange distributes physical stress across a larger surface area, providing excellent resistance to vibration and physical impact.

• Superior Grounding: Flush mounting against a metal chassis ensures a broad, low-resistance ground connection, which is essential for minimizing EMI/RFI.

• Low VSWR Performance: Precision-machined to maintain a strict 50 Ohm impedance, ensuring high signal integrity and minimal insertion loss in microwave signal paths.

• Anti-Rotation Design: Once bolted down, the connector cannot spin or loosen, protecting internal solder joints from mechanical fatigue.

• High-Frequency Reliability: Optimized for stable electrical performance from DC up to 18 GHz (depending on the specific grade).

Key Features

• 4-Hole Square Flange: Allows for a flush and permanent mount on panels using standard M2 or M2.5 screws.

• Solder Termination: Features a convenient solder cup or flat tab for easy and reliable internal connections.

• Teflon (PTFE) Insulator: High-purity dielectric ensures stable signal transmission and high heat resistance during the soldering process.

• Standard SMA Female Interface: Features a 1/4-36 threaded barrel and gold-plated beryllium copper socket for universal compatibility.

• Premium Materials: Constructed from gold-plated brass or stainless steel for maximum durability and corrosion resistance.
