TNC Male Right Angle RF Coaxial Connector for LMR300 Cable (Clamp Type) (TERUILAI P/N: TNC-JW300A) Full Product Specification

1. Core Product Overview

This TNC male right angle RF coaxial connector is a medium-power screw-coupling coaxial connector specifically designed for LMR300 coaxial cables, adopting a clamp termination method and 90-degree bent structure. The TNC series supports a DC-11GHz operating frequency range and is available in two intermateable versions of 50Ω and 95Ω, featuring high reliability, excellent vibration resistance, and superior mechanical and electrical properties. This particular model supports a DC-3GHz operating frequency range and complies with RoHS environmental protection standards.

2. Core Product Features

2.1 Space-saving Right Angle Structure

  • 90-degree right angle design effectively saves vertical installation space and optimizes cable routing

  • Perfectly matched with LMR300 coaxial cables to ensure consistent impedance throughout the entire connection path

  • Ideal for space-constrained equipment installation and tight wiring scenarios

2.2 Robust Screw-Coupling Vibration Resistance

  • Adopts a reliable screw-coupling mechanism, providing excellent vibration and shock resistance

  • Ensures long-term stable mechanical and electrical connection even under severe vibration conditions

  • Suitable for outdoor and industrial environments with high reliability requirements

2.3 Convenient Clamp Termination

  • Clamp-type termination enables quick and reliable on-site cable assembly without soldering

  • Provides firm mechanical fixation and stable electrical connection with LMR300 cables

  • Equipped with dedicated silicon rubber gasket and brass washer for enhanced sealing and fixation performance

2.4 Ultra-low Loss Electrical Performance

  • Supports DC-3GHz operating frequency range with a characteristic impedance of 50Ω

  • Exceptionally low contact resistance: center conductor ≤1.5mΩ, outer conductor ≤0.2mΩ, achieving minimal signal attenuation

  • Dielectric withstanding voltage of 1500V (RMS) and insulation resistance ≥5000MΩ, guaranteeing safe and stable operation

  • All-metal shielding structure effectively suppresses electromagnetic interference and ensures signal integrity

2.5 Excellent Durability & Wide Temperature Adaptability

  • Durability of ≥500 mating cycles, suitable for long-term repeated use

  • Ultra-wide operating temperature range: -45℃ ~ +125℃, adapting to various extreme working environments

  • High-quality nickel plating on brass components provides excellent corrosion and oxidation resistance
