The **14CEC-215D-R** is a specific part number typically associated with **RJ45 Integrated Connector Modules (ICMs)**, often manufactured by companies like **Link-Com** or similar magnetic component specialists. These components are essential in networking hardware, combining a standard RJ45 jack with the necessary "magnetics" (transformers and filters) required for Ethernet communication. --- ## 1. Technical Specifications Below is a breakdown of the typical electronic characteristics for this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | RJ45 Connector with Integrated Magnetics | | **Port Configuration** | Single Port (1x1), Tab-Down | | **Ethernet Speed** | 10/100/1000 Base-T (Gigabit Ethernet) | | **LED Configuration** | Green / Yellow (Integrated) | | **Isolation Voltage** | 1500 Vrms (Minimum) | | **Turn Ratio** | 1CT:1CT (Transmitter & Receiver) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Suffix "-R" usually denotes RoHS) | --- ## 2. Key Electronic Components Inside An "Integrated" connector like the 14CEC-215D-R is not just a plastic housing; it contains a miniature PCB with the following circuits: ### A. Isolation Transformers These provide galvanic isolation between the PHY (Physical Layer) chip and the network cable. This protects the sensitive circuitry from high-voltage surges and static electricity on the Ethernet line. ### B. Common Mode Chokes Integrated chokes filter out electromagnetic interference (EMI). They ensure that the differential signals used in Ethernet are clean and that the device meets FCC/CE emission standards. ### C. Termination Resistors (Bob Smith Termination) These are used to reduce common-mode noise and match the impedance of the twisted-pair cables (typically 75 ohms to a common capacitor). ### D. Integrated LEDs The "215D" segment of the part number often indicates the specific color and wiring of the status LEDs (Link/Activity) built directly into the front of the jack. --- ## 3. Physical Layout and Mounting * **Form Factor:** Right-angle, Through-hole (THT) mounting. * **Shielding:** The entire unit is encased in a metal "can" (shield) to provide a path to ground for ESD and to minimize noise interference. * **Tab Direction:** "Tab-Down" refers to the orientation of the plastic locking clip on the Ethernet cable when inserted. --- ## 4. Typical Applications This part is commonly found in: * **Embedded Systems:** Single-board computers (SBCs) or IoT gateways. * **Networking Gear:** Switches, routers, and network interface cards (NICs). * **Industrial Equipment:** Programmable Logic Controllers (PLCs) with Ethernet ports.
