## SFHR-02V-R Connector Specifications The **SFHR-02V-R** is a high-precision, small-form-factor wire-to-board crimp style connector housing manufactured by **JST (Japan Solderless Terminals)**. It belongs to the **SFH series**, which is specifically designed for high-density applications, such as LED backlight power supplies in LCD displays. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Series** | SFH | | **Pitch** | 1.8 mm | | **Number of Positions** | 2 | | **Connector Type** | Receptacle Housing (Crimp) | | **Contact Gender** | Female (Socket) | | **Voltage Rating** | 350V AC/DC | | **Current Rating** | 4A (using AWG #22 wire) | | **Operating Temperature** | -25°C to +85°C | | **Material** | Thermoplastic (PA 66), UL94V-0 | | **Color** | Red (indicated by the "-R" suffix) | --- ### Key Features and Design 1. **Compact Low Profile:** With a 1.8mm pitch and a side-entry height of only 3.0mm, it is ideal for thin electronic devices where space is at a premium. 2. **Polarization and Locking:** The housing features a polarized design to prevent incorrect insertion and a secure friction-lock mechanism to ensure the connector remains seated under vibration. 3. **High Voltage Capability:** Despite its small size, it is rated for up to 350V, making it suitable for driving LED arrays. 4. **Color Coding:** The "R" at the end of the part number stands for **Red**. JST uses color-coded housings to help technicians identify different circuits during assembly. --- ### Compatible Components To create a functional connection, the SFHR-02V-R must be paired with specific terminals and headers: * **Crimp Terminal:** SSHL-003T-P0.2 (Supports AWG #30 to #26) or SSHL-002T-P0.2 (Supports AWG #28 to #22). * **Mating Header:** SM02B-SFHRS-TF (Side entry, surface mount). --- ### Common Applications * **LCD/LED Displays:** Powering backlight strips. * **Handheld Devices:** Battery or sensor connections. * **Industrial Controls:** Small signal or power transmission in tight enclosures.
