SRF0703-470M Frequently Asked Questions (FAQs)

  • The recommended land pattern for the SRF0703-470M can be found in the Bourns application note AN-13, which provides guidelines for PCB layout and land pattern design.
  • During reflow soldering, the SRF0703-470M should be exposed to a peak temperature of 260°C for no more than 20-30 seconds. It's also recommended to use a nitrogen atmosphere to minimize oxidation.
  • The SRF0703-470M can operate safely within a temperature range of -40°C to 125°C. However, the inductor's performance may degrade at extreme temperatures, so it's essential to consider the application's operating conditions.
  • To minimize EMI, ensure the SRF0703-470M is placed away from sensitive components and cables. Additionally, use shielding, grounding, and filtering techniques to reduce electromagnetic radiation.
  • Store the SRF0703-470M in its original packaging or a similar ESD-protective package. Handle the component by the body, avoiding touching the leads or electrical contacts to prevent damage or contamination.
