MSS1278-473MLD Frequently Asked Questions (FAQs)

  • The recommended land pattern for the MSS1278-473MLD 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 recommends derating the inductor's current rating for extended operation above 85°C. Consult Coilcraft's application notes for more information on high-temperature operation.
  • Yes, the MSS1278-473MLD is suitable for high-frequency applications up to several hundred MHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure it does not coincide with the operating frequency to avoid unwanted resonances.
  • While the datasheet does not specify a maximum voltage rating, Coilcraft recommends limiting the voltage across the inductor to 50 Vrms or less to ensure reliable operation and prevent damage.
  • The MSS1278-473MLD is designed to operate within its specified current rating. If the inductor is subjected to excessive current, it may saturate, leading to reduced inductance and increased core losses. Consult Coilcraft's application notes for guidance on inductor saturation and how to mitigate its effects.
