ERJ3EKF1782V - Panasonic

ERJ3EKF1782V Frequently Asked Questions (FAQs)

• What is the recommended land pattern for ERJ3EKF1782V?
  The recommended land pattern for ERJ3EKF1782V is a rectangular pad with a size of 1.3mm x 0.8mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask clearance of 0.1mm.
• How do I handle the ERJ3EKF1782V during reflow soldering?
  During reflow soldering, the ERJ3EKF1782V should be placed on a flat surface to prevent tombstoning. The component should be aligned with the PCB pads and the solder paste should be applied evenly. The recommended reflow temperature profile is 250°C for 10-30 seconds.
• Is the ERJ3EKF1782V suitable for high-frequency applications?
  The ERJ3EKF1782V is a general-purpose resistor and is not specifically designed for high-frequency applications. However, it can be used up to 100 MHz with minimal signal attenuation. For higher frequencies, a high-frequency resistor with a lower ESL (equivalent series inductance) should be considered.
• Can I use the ERJ3EKF1782V in a high-temperature environment?
  The ERJ3EKF1782V has a maximum operating temperature of 150°C. While it can withstand short-term excursions up to 200°C, prolonged exposure to high temperatures can affect its reliability and lifespan. If your application requires operation above 150°C, a high-temperature resistor should be considered.
• How do I ensure the ERJ3EKF1782V meets my application's power rating requirements?
  The ERJ3EKF1782V has a power rating of 0.25W. To ensure it meets your application's power rating requirements, calculate the maximum power dissipation using the formula P = V^2/R, where V is the voltage across the resistor and R is the resistance value. Ensure the calculated power does not exceed the rated power of 0.25W.
