SRP1270-4R7M Frequently Asked Questions (FAQs)

  • The recommended land pattern for SRP1270-4R7M can be found in the Bourns application note AN-13, which provides guidelines for surface mount assembly of inductors.
  • The SRP1270-4R7M has a maximum operating temperature of 125°C. Ensure that the inductor is not exposed to temperatures above this rating, and provide adequate thermal relief paths on the PCB to prevent overheating.
  • Bourns recommends a soldering profile with a peak temperature of 240°C for 3-5 seconds, with a ramp-up rate of 3°C/s and a ramp-down rate of 6°C/s.
  • Yes, the SRP1270-4R7M is designed to withstand vibrations up to 20 G's, making it suitable for use in high-vibration environments.
  • To ensure magnetic shielding, keep the inductor at least 2 mm away from other magnetic components, and use a shielded enclosure or a mu-metal shield around the inductor if necessary.
