SRP1238A-4R7M Frequently Asked Questions (FAQs)

  • The recommended land pattern for SRP1238A-4R7M is a rectangular pad with a size of 1.3 mm x 0.8 mm, with a non-solder mask defined (NSMD) pad shape.
  • SRP1238A-4R7M is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
  • To minimize EMI, it's recommended to use a shielded enclosure or a metal can, and to connect the shield to the circuit ground. Additionally, keep the inductor away from other components and avoid routing sensitive signals near the inductor.
  • The self-resonant frequency of SRP1238A-4R7M is typically above 100 MHz, but it can vary depending on the specific application and PCB layout.
  • SRP1238A-4R7M is rated for a maximum current of 1.3 A, but it's recommended to derate the current rating based on the ambient temperature and the desired reliability level.
