Based on electronic component nomenclature and common industry standards, **KSF-KSF-R** typically refers to a specific series of **Wire-to-Board Connectors** or **Pin Header Assemblies**, often associated with manufacturers like JST (specifically the KS series) or generic high-density connector brands. Below is a breakdown of the technical aspects of this electronic part. --- ### 1. General Specifications The "KSF" designation usually implies a **crimp-style** or **IDC (Insulation Displacement Connector)** housing intended for high-reliability connections in compact electronic devices. | Feature | Specification (Typical) | | :--- | :--- | | **Pitch** | 1.0mm or 1.25mm (Ultra-low profile) | | **Current Rating** | 1.0A AC/DC | | **Voltage Rating** | 50V to 100V AC/DC | | **Temperature Range** | -25°C to +85°C | | **Termination Style** | Through-hole or SMT (Surface Mount) | --- ### 2. Part Number Breakdown While manufacturer-specific codes vary, the "R" suffix in electronic components almost always denotes compliance or packaging types. * **KSF**: The Series/Family Name (identifies the physical dimensions and mating interface). * **KSF (Secondary)**: Often denotes a male/female pair or a specific orientation (e.g., Vertical vs. Right Angle). * **-R**: Typically stands for **RoHS Compliant** (Restriction of Hazardous Substances) or **Tape & Reel** packaging for automated SMT assembly. --- ### 3. Key Electronic Characteristics These parts are engineered for signal integrity and space-saving. * **Contact Resistance**: Low initial resistance (usually < 20mΩ) to ensure minimal signal loss. * **Insulation Resistance**: High threshold (e.g., 100MΩ min) to prevent leakage between closely spaced pins. * **Locking Mechanism**: Often features a friction lock or a small "click" latch to prevent accidental disconnection due to vibration. * **Material**: The housing is usually made of heat-resistant plastic (like Nylon 66 or LCP) to withstand reflow soldering temperatures. --- ### 4. Common Applications Due to their small footprint, these connectors are found in: 1. **LCD Displays**: Connecting backlight units to the main driver board. 2. **Handheld Devices**: Linking batteries or small speakers to the PCB. 3. **Drones/Robotics**: Used in sensor arrays where weight and space are critical. 4. **LED Lighting**: Connecting strips to power controllers. --- ### 5. Schematic Symbol & Footprint If you are using this in a CAD tool like Altium or KiCad, the footprint typically follows this logic: ```c // Example Footprint Logic for KSF-1.0-R Pins: 2 to 20 (Depending on variant) Type: Surface Mount (SMT) or Through-hole Lead Pitch: 1.0mm Orientation: Right-angle (-R sometimes implies Right-angle in specific brands) ```
