WR06X3902FTL

The WR06X3902FTL is a precision resistor manufactured by Walsin Technology, known for its reliability and performance in various electronic applications. This specific component is a surface-mount resistor, which means it is designed to be mounted directly onto the surface of a printed circuit board (PCB), allowing for a compact design and efficient use of space.

Key Features:

1. Resistance Value: The WR06X3902FTL has a resistance value of 39 kΩ (39,000 ohms), making it suitable for applications requiring moderate resistance levels.

2. Tolerance: This resistor typically comes with a tolerance of ±1%, which indicates that the actual resistance can vary by this percentage from the nominal value. This level of precision is essential for applications where accuracy is critical.

3. Power Rating: The WR06X3902FTL is rated for a power dissipation of 1/10 watt (0.1W), which means it can safely handle this amount of power without overheating. This makes it suitable for low-power applications.

4. Temperature Coefficient: The temperature coefficient is usually specified in parts per million per degree Celsius (ppm/°C), indicating how much the resistance value changes with temperature. A lower coefficient is preferable for stable performance across varying temperatures.

5. Package Size: The WR06 series typically comes in a compact 0603 package size (0.06 inches by 0.03 inches), which is standard for surface-mount technology (SMT) components. This small size allows for high-density PCB designs.

6. Material Composition: The resistor is made from a thin film or thick film material, which contributes to its stability and reliability. The choice of material affects the resistor's performance characteristics, including noise and temperature stability.

7. Applications: The WR06X3902FTL is suitable for a wide range of applications, including consumer electronics, telecommunications, automotive electronics, and industrial equipment. Its reliability makes it a good choice for both commercial and industrial designs.

8. RoHS Compliance: Walsin Technology typically ensures that their components, including the WR06X3902FTL, comply with RoHS (Restriction of Hazardous Substances) standards, making them environmentally friendly and safe for use in electronic devices.

Conclusion:

The WR06X3902FTL from Walsin Technology is a versatile and reliable surface-mount resistor that meets the needs of various electronic applications. Its combination of precise resistance value, compact size, and robust performance characteristics makes it an excellent choice for engineers and designers looking to optimize their circuit designs.
