The **STPKCH7RD** is a specific part number for a high-performance **Category 5e (Cat5e) Shielded Patch Cord** manufactured by **Panduit**. While it is an assembly rather than an individual semiconductor, its electronic characteristics are critical for high-speed data transmission in industrial and enterprise environments. --- ## 1. Technical Specifications Below are the core technical parameters for the STPKCH7RD: | Feature | Specification | | :--- | :--- | | **Cable Type** | S/FTP (Shielded/Foiled Twisted Pair) | | **Performance Level** | Category 5e (Cat5e) | | **Conductor Gauge** | 26 AWG | | **Length** | 7 Meters | | **Color** | Red (RD) | | **Termination** | RJ45 Modular Plugs (Gold Plated) | | **Jacket Material** | CM (Communication General Purpose) | --- ## 2. Electronic Components & Design ### A. Conductors and Shielding The internal "electronics" of the cable focus on signal integrity and electromagnetic compatibility (EMC): * **Stranded Copper:** Uses 26 AWG stranded copper conductors which provide flexibility for patching while maintaining low electrical resistance. * **Shielding (S/FTP):** Each pair is wrapped in foil, and an overall braid shield surrounds the bundle. This design prevents **EMI (Electromagnetic Interference)** and **RFI (Radio Frequency Interference)** from corrupting the data stream. ### B. The RJ45 Connector The ends of the cable feature specialized modular plugs: * **Gold Plated Contacts:** The pins are typically plated with 50 micro-inches of gold. This ensures high conductivity and prevents oxidation/corrosion over time. * **Internal PCB/Wiring:** While standard RJ45s are passive, the geometry of the wire layout inside the plug is engineered to minimize **Crosstalk (NEXT)**. --- ## 3. Electrical Performance Standards The STPKCH7RD is designed to meet specific electronic transmission requirements: 1. **Impedance:** 100 Ohms (nominal). 2. **Frequency:** Rated for up to 100 MHz. 3. **Data Rate:** Supports up to 1000BASE-T (Gigabit Ethernet). 4. **PoE Compatibility:** Rated for **IEEE 802.3af/at (PoE/PoE+)** and **802.3bt (Type 3 and Type 4)**, meaning it can safely carry DC power to devices like IP cameras or VoIP phones. --- ## 4. Part Number Breakdown The Panduit nomenclature for this part is structured as follows: | Code | Meaning | | :--- | :--- | | **STP** | Shielded Twisted Pair | | **K** | Keyed (or high-performance variant) | | **CH** | Category 5e Patch Cord | | **7** | 7 Meters in length | | **RD** | Red color |
