It is part of the CRCW series, known for its high precision and reliability in various electronic circuits. The resistor features a compact 0805 package size, making it suitable for space-constrained designs. With a resistance value of 7.87 ohms and a power rating of 0.5W, this resistor is widely used in automotive, industrial, and consumer electronics. Its robust construction ensures stable performance even under harsh environmental conditions, making it a preferred choice for demanding applications.
Structure and Working Principle
The CRCW08057R87FNTB consists of a ceramic substrate coated with a thick film resistive element. The resistive layer is typically made of ruthenium oxide, which provides excellent stability and low temperature coefficient of resistance (TCR). The resistor is terminated with nickel and tin plating for reliable soldering. When integrated into a circuit, the resistor limits the flow of electric current, converting excess energy into heat. The thick film design ensures uniform current distribution, minimizing hotspots and enhancing durability. The 0805 package size (2.0mm x 1.25mm) allows for easy placement on printed circuit boards (PCBs) using automated assembly equipment.
Key Features
The CRCW08057R87FNTB offers several key features, including high precision with a tolerance of ±1% and a low TCR of ±100ppm/°C. These characteristics ensure consistent performance across a wide temperature range. The resistor is also RoHS compliant, meeting environmental safety standards. Its compact size and surface mount design make it ideal for high-density PCB layouts. The thick film technology provides excellent resistance to mechanical stress and environmental factors such as humidity and temperature fluctuations. These features make the CRCW08057R87FNTB a reliable component for critical applications.
Application Areas
This resistor is commonly used in automotive electronics, where reliability and stability are paramount. It is found in engine control units (ECUs), sensors, and infotainment systems. Industrial applications include power supplies, motor controls, and instrumentation. In consumer electronics, the CRCW08057R87FNTB is used in smartphones, tablets, and wearable devices. Its compact size and high precision make it suitable for miniaturized circuits. The resistor is also used in medical devices and telecommunications equipment, where consistent performance is essential.
Maintenance and Precautions
To ensure longevity, the CRCW08057R87FNTB should be handled with care during assembly. Excessive mechanical stress or bending of the PCB can damage the resistor. It is also important to avoid exposing the component to high humidity or corrosive environments. When soldering, follow recommended temperature profiles to prevent thermal shock. Storage conditions should be dry and free from contaminants. Regular inspection of the resistor for signs of damage or degradation can help maintain circuit reliability.
B2B Procurement Guide
When procuring the CRCW08057R87FNTB, verify the manufacturer's specifications to ensure compatibility with your application. Check for certifications such as RoHS compliance and industry standards like AEC-Q200 for automotive use. Bulk purchasing can reduce costs, but ensure the supplier provides authentic components to avoid counterfeit products. Lead times and minimum order quantities (MOQs) should be considered for production planning. Reliable distributors often offer technical support and datasheets for further reference.
