The part number **PRNF2ABT10K2** refers to a high-precision, automotive-grade thin film chip resistor manufactured by **Stackpole Electronics**. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Part Number Decoder The alphanumeric code provides specific details about the component's construction and performance: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **PRNF** | Series Name | High Precision Thin Film Chip Resistor (Automotive Grade) | | **2** | Power Rating | 0.5W (1/2 Watt) | | **A** | Case Size | 0805 (Metric 2012) | | **B** | Tolerance | ±0.1% (Tight precision) | | **T** | Temperature Coefficient | ±10 ppm/°C (Ultra-stable) | | **10K2** | Resistance Value | 10.2 kΩ (10,200 Ohms) | --- ## 2. Technical Specifications This resistor is designed for high-reliability applications where accuracy and stability across temperature changes are critical. ### Electrical Characteristics * **Resistance:** 10.2 kΩ * **Tolerance:** ±0.1% (This ensures the actual resistance is between 10.1898 kΩ and 10.2102 kΩ). * **Power Rating:** 0.5 Watts (at 70°C). * **Maximum Working Voltage:** 150V. * **Temperature Coefficient (TCR):** ±10 ppm/°C. This means the resistance will only change by 10 parts per million for every degree Celsius change in temperature. ### Physical & Environmental * **Package Type:** Surface Mount (SMD/SMT). * **Case Size:** 0805. * **Operating Temperature:** -55°C to +155°C. * **Compliance:** AEC-Q200 Qualified (Automotive grade) and RoHS compliant. --- ## 3. Key Applications Because of its high precision and low temperature drift, the PRNF2ABT10K2 is typically used in: 1. **Automotive Electronics:** Control units (ECUs), sensor interfaces, and battery management systems. 2. **Medical Equipment:** High-accuracy diagnostic tools and monitoring devices. 3. **Industrial Controls:** Precision scales, measurement instrumentation, and feedback loops in power supplies. 4. **Telecommunications:** Base station equipment where signal integrity is vital. --- ## 4. Why Use "Thin Film"? This part uses **Thin Film** technology rather than the common "Thick Film." * **Benefit:** Thin film resistors offer much lower noise, better stability over time, and significantly lower TCR (Temperature Coefficient). * **Trade-off:** They are generally more expensive and more sensitive to moisture if not properly encapsulated (though the PRNF series is ruggedized for automotive use).
