MSS1278H-393MED Frequently Asked Questions (FAQs)

  • Coilcraft provides a recommended land pattern for MSS1278H-393MED in their documentation, which can be found on their website. The recommended land pattern is designed to ensure optimal performance and reliability of the inductor.
  • MSS1278H-393MED is rated for operation up to 125°C, but it's recommended to derate the current rating at higher temperatures. Coilcraft provides a temperature derating curve in their documentation, which can help engineers determine the maximum current rating at their specific operating temperature.
  • The magnetic field of MSS1278H-393MED can affect nearby components and cause electromagnetic interference (EMI). To mitigate this, engineers can use shielding, orient the inductor to minimize the magnetic field, and keep sensitive components at a safe distance.
  • The self-resonant frequency of MSS1278H-393MED is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Coilcraft provides a self-resonant frequency calculator on their website, which can help engineers determine the self-resonant frequency of the inductor.
  • MSS1278H-393MED is designed to withstand moderate vibration, but it's recommended to evaluate the inductor's performance in the specific vibration environment. Coilcraft provides vibration testing data and guidelines for evaluating the inductor's performance in high-vibration environments.
