The **PCC-SMP-N-5-R** is a specific surface-mount connector, typically used for temperature sensing applications involving thermocouples. It is manufactured by **Omega Engineering**. --- ### 1. Technical Specifications This component is a miniature SMT (Surface Mount Technology) connector header designed to interface thermocouple probes with a Printed Circuit Board (PCB). | Feature | Specification | | :--- | :--- | | **Model Type** | PCC (PCB Connector) | | **Calibration Type** | **N** (Nicrosil-Nisil) | | **Mounting Style** | SMP (Surface Mount Package) | | **Lead Spacing** | 5 mm (standard for the R series) | | **Body Material** | High-performance Glass-filled Nylon | | **Max Temperature** | Approx. 260°C (Reflow Solder compatible) | --- ### 2. Detailed Part Breakdown The alphanumeric code provides specific details about the electronic and physical properties: * **PCC:** Indicates it is a connector designed for Printed Circuit Board mounting. * **SMP:** Stands for "Surface Mount Package." This means it is designed to be soldered onto the surface of a PCB rather than through-hole. * **N:** This is the **Thermocouple Type**. "N" type thermocouples are used for high-temperature stability and resistance to oxidation. The connector contacts are made of the actual thermocouple alloys to minimize cold junction errors. * **5:** Refers to the lead spacing or a specific physical dimension variant (5mm). * **R:** Indicates that the part is supplied in **Tape and Reel** packaging, which is essential for automated pick-and-place assembly lines. --- ### 3. Key Electronic Characteristics * **Material Compatibility:** The internal pins are made of Nicrosil (+) and Nisil (-) alloys. This ensures that the junction between the board and the probe does not introduce parasitic EMF (voltage) that would skew temperature readings. * **Cold Junction Compensation:** These connectors are often used alongside a temperature sensor (like a thermistor or RTD) placed near the pads to provide accurate cold-junction compensation. * **Reflow Stability:** Since it is an SMT part, the plastic housing is engineered to withstand the high heat of a reflow oven (convection or infrared). --- ### 4. Common Applications 1. **Industrial Controllers:** Used in PID controllers that require Type N thermocouple inputs. 2. **Handheld Meters:** Compact PCB designs for portable thermometers. 3. **Data Loggers:** Multi-channel systems where space-saving SMT components are required.
