AC1206JR-07390RL

The AC1206JR-07390RL is a specific type of resistor manufactured by Yageo, a well-known company in the electronic components industry. This component is part of their extensive range of passive components, particularly focusing on surface mount technology (SMT) resistors.

Detailed Description:

1. Type and Configuration:

   • The AC1206JR-07390RL is a surface mount resistor, which means it is designed to be mounted directly onto the surface of printed circuit boards (PCBs). The "1206" in its name refers to its package size, which measures 0.12 inches by 0.06 inches (3.2 mm x 1.6 mm). This size is commonly used in various electronic applications due to its compactness and ease of handling.

2. Resistance Value:

   • The resistor has a nominal resistance value of 390 ohms. This value indicates the amount of resistance it provides to the flow of electric current, which is crucial for controlling voltage and current levels in electronic circuits.

3. Tolerance:

   • The "J" in the part number signifies a tolerance of ±5%. This means that the actual resistance can vary by 5% above or below the nominal value of 390 ohms. Tolerance is an important specification as it affects the precision of the resistor in a circuit.

4. Power Rating:

   • The AC1206JR-07390RL typically has a power rating of 1/4 watt (0.25W). This rating indicates the maximum amount of power the resistor can dissipate without being damaged. It is essential to ensure that the power rating is not exceeded in practical applications to avoid overheating and potential failure.

5. Temperature Coefficient:

   • This resistor has a temperature coefficient of ±100 ppm/°C, which indicates how much the resistance value can change with temperature variations. A lower temperature coefficient is preferable for applications requiring high stability over a range of temperatures.

6. Construction and Material:

   • The resistor is constructed using a thick film technology, which involves applying a resistive material onto a ceramic substrate. This construction method is known for its reliability and stability, making it suitable for a wide range of applications.

7. Applications:

   • The AC1206JR-07390RL is suitable for various applications, including consumer electronics, automotive systems, telecommunications, and industrial equipment. Its compact size and reliable performance make it ideal for use in densely packed circuit boards.

8. RoHS Compliance:

   • Yageo's components, including this resistor, are typically RoHS compliant, meaning they are free from hazardous substances such as lead, mercury, and cadmium, aligning with environmental regulations.

9. Packaging:

   • The resistor is usually supplied in tape and reel packaging, which facilitates automated assembly processes in manufacturing environments. This packaging method allows for easy handling and placement on PCBs.

In summary, the AC1206JR-07390RL from Yageo is a reliable, compact surface mount resistor with a resistance value of 390 ohms, a tolerance of ±5%, and a power rating of 1/4 watt. Its construction and specifications make it suitable for a wide range of electronic applications, ensuring performance and stability in various environments.
