180 Degree RJ9 Telephone Female Socket, 1 Port, Unshielded, Surface Mount, Tab-Up, No LED
Introduction:
This is a single port 180 degree RJ9 telephone female socket designed for stable top-entry surface mount attachment to printed circuit boards. It features a hi-temp thermoplastic housing specifically engineered to survive intense industrial reflow soldering processes without warping. The 4P4C interface utilizes Gold plated Phosphor Bronze contacts to ensure superior conductivity and a consistent 1.5A current rating. Utilizing a Tab-Up vertical configuration, this unshielded component effectively saves PCB surface area while maintaining a high insulation resistance of 1000 mohms. Technicians utilize this reliable modular interface for telephone handsets and telecommunication gear requiring secure vertical SMT connectivity.
Key Features
- Vertical SMT Design: Optimizes top-entry connectivity for compact board layouts.
- Gold Plated Contacts: Ensures superior conductivity and lasting signal stability.
- Hi-Temp Thermoplastic: Survives intense heat during industrial reflow soldering.
- 4P4C RJ9 Interface: Provides standard modular connectivity for voice systems.
- 1.5A Current Support: Handles efficient power delivery for telecommunication hardware.
