SMB F PCB MOUNT SOLDER

Description

The SMB Female PCB Mount Solder Connector is a subminiature RF interface designed for engineers who require a compact and efficient board-to-cable transition. This connector features a straight (vertical) configuration with precision-machined solder legs, allowing it to be mounted directly into through-hole cutouts on a PCB. By eliminating the need for intermediate cable assemblies, it provides a low-inductance connection that preserves signal integrity for high-frequency applications.

Built for performance from DC up to 4 GHz, the SMB female (jack) interface utilizes a professional snap-on coupling mechanism. This ensures a secure, vibration-resistant mechanical lock when mated with an SMB male plug, accompanied by a distinct “click” to confirm full engagement. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, this connector ensures minimal signal attenuation and superior protection against oxidation. Its small footprint is ideal for high-density layouts where board real estate is at a premium, such as in GPS receivers, automotive telematics, and medical instrumentation.

Key Technical Advantages

• Optimized Board Real Estate: The subminiature SMB footprint allows for high-density port placement, enabling multiple RF channels to be integrated into a single small-form-factor PCB.

• Superior Signal Integrity: Direct through-hole soldering minimizes the transition distance between the board traces and the RF interface, reducing parasitic capacitance and signal loss.

• Vibration-Proof Mating: The snap-on interface provides a reliable mechanical connection that is inherently resistant to loosening in high-motion environments, outperforming threaded connectors in mobile applications.

• Rapid Assembly Integration: The tool-free mating mechanism facilitates fast production testing and final assembly, significantly reducing labor time compared to SMA or other threaded interfaces.

• High-Grade Thermal Stability: Equipped with a PTFE dielectric that maintains its structural integrity during the soldering process and throughout extreme operating temperature cycles.

Key Features

• Interface Type: SMB Female (Jack) with 50-Ohm snap-on interface.

• Mounting Style: Straight Through-Hole (THT) PCB Mount.

• High-Conductivity Contacts: Gold-over-nickel plating on the body and center contact ensures low contact resistance and excellent solderability.

• Broadband Range: Supports reliable RF and microwave signal transmission from DC up to 4 GHz.

• Industrial Compliance: Fully compliant with standard SMB interface specifications for universal intermateability with all SMB male (plug) connectors.
