2929SQ-391JEB Frequently Asked Questions (FAQs)

  • The recommended land pattern for the 2929SQ-391JEB can be found in Coilcraft's application note AN-40, which provides detailed guidelines for PCB layout and land pattern design.
  • While the datasheet specifies an operating temperature range of -40°C to +125°C, Coilcraft's inductors are designed to maintain their inductance and Q values within a certain tolerance up to 150°C. However, it's recommended to consult with Coilcraft's application engineers for specific high-temperature requirements.
  • The SRF of the 2929SQ-391JEB is not explicitly stated in the datasheet, but it can be estimated using Coilcraft's online SRF calculator tool or by consulting with their application engineers.
  • While the 2929SQ-391JEB has a rated current of 3.9 A, its high-current capability depends on the specific application and PCB design. Coilcraft recommends consulting with their application engineers to determine the inductor's suitability for high-current applications.
  • Yes, the 2929SQ-391JEB is suitable for use in switching regulators due to its low DC resistance and high Q values. However, it's essential to ensure that the inductor is properly selected and designed into the circuit to meet the specific requirements of the switching regulator.
