SRR1240-120M Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
  • Bourns recommends derating the current rating of the inductor by 1.5% per degree Celsius above 40°C to ensure reliable operation in high-temperature environments.
  • The maximum allowable DC current for the SRR1240-120M is 12.4A, which is the rated current at 40°C. Exceeding this current may cause the inductor to overheat and reduce its lifespan.
  • Yes, the SRR1240-120M is suitable for high-frequency switching applications up to 1MHz. However, it's essential to consider the inductor's core loss, winding loss, and self-resonant frequency to ensure optimal performance.
  • To minimize the impact of the inductor's magnetic field, Bourns recommends keeping other components at least 5mm away from the inductor, and using shielding or magnetic shielding materials if necessary.
