SMZ F Solder Type for LMR100/RG174/RG316 Cable

Description

The SMZ Female (Jack) Solder Type Connector is a specialized 75-Ohm RF interface frequently utilized in European and UK telecommunications infrastructure. While the SMZ (BT43) series is a standard for telephony, this variant is precision-machined to accommodate high-performance micro-cables such as LMR100, RG174, and RG316. The solder-type center contact is designed for applications where electrical permanence and minimum contact resistance are critical, providing a fused signal path that is superior to mechanical crimping for sensitive digital data streams.

Maintaining the strict 75-Ohm impedance required for telecommunications standards, this connector is essential for preventing signal reflections in digital distribution environments. The female interface features a high-strength snap-on coupling mechanism that provides a secure, vibration-resistant mechanical lock with a distinct “click” upon mating. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, it delivers exceptional electrical stability and long-term protection against corrosion in mission-critical hardware environments.

Key Technical Advantages

• Permanent Solder Center Contact: Provides a high-conductivity, fused electrical path that ensures maximum signal fidelity and minimizes return loss compared to standard crimp pins.

• Micro-Cable Compatibility: Specifically calibrated for the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring a seamless mechanical fit and optimized signal path.

• 75-Ohm System Precision: Engineered to maintain critical impedance matching for digital telephony and high-speed data exchange standards.

• Robust Snap-On Interface: The SMZ (BT43) mechanism offers a more substantial and secure mechanical mating than standard SMB connectors, making it ideal for high-density patching.

• Superior Thermal and Chemical Stability: Features a high-grade PTFE dielectric that maintains its geometry and electrical properties during the professional soldering process.
