The **14CEC-2504-R** is a specific type of electronic connector, commonly classified under the category of **High-Density, SMT (Surface Mount Technology) Connectors**. It is widely used in compact electronic devices such as laptops, tablets, and mobile peripherals. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. General Specifications The 14CEC series generally refers to high-pin-count interface connectors designed for high-speed data transmission. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Often associated with manufacturers like **ACES** or similar electronics component groups. | | **Mounting Type** | SMT (Surface Mount Technology) / SMD | | **Pitch** | Typically 0.4mm or 0.5mm (Ultra-fine pitch) | | **Pin Count** | 25-pin (indicated by the '25' in the part number) | | **Termination** | Right-Angle or Vertical (depending on exact board layout) | --- ### 2. Electrical Characteristics These connectors are engineered to handle low-voltage signals with high integrity. * **Current Rating:** Usually 0.3A to 0.5A per pin. * **Voltage Rating:** Typically 50V AC/DC. * **Insulation Resistance:** 100MΩ Minimum. * **Contact Resistance:** 40mΩ Maximum (initial). * **Dielectric Withstanding Voltage:** 250V AC for 1 minute. --- ### 3. Material Composition To ensure durability and conductivity, the materials are chosen for high-performance environments. * **Housing:** High-temperature thermoplastic (UL94V-0 rated), usually LCP (Liquid Crystal Polymer). * **Contacts:** Copper alloy (Phosphor Bronze or Brass). * **Plating:** Gold plating on the contact area to prevent oxidation and ensure stable signal transmission; Tin plating on the solder tails. * **Reinforcement:** Metal ear/tabs for additional PCB retention and grounding. --- ### 4. Applications The 14CEC-2504-R is primarily found in the following hardware: 1. **Display Panels:** Connecting LCD/OLED screens to the mainboard. 2. **Camera Modules:** High-speed image data transfer. 3. **Battery Management Systems (BMS):** Data monitoring pins for smart batteries. 4. **Flexible Printed Circuits (FPC):** Acting as the mating interface for ribbon cables. --- ### 5. Part Number Decoding (Typical) While naming conventions vary slightly by manufacturer, the code usually breaks down as follows: | Segment | Meaning | | :--- | :--- | | **14CEC** | Series identifier (Designates the style and form factor) | | **25** | Number of circuits/positions (25 pins) | | **04** | Pitch or specialized design variant | | **R** | Packaging (usually signifies **Tape & Reel** for automated assembly) |
