WBC4-1WLC Frequently Asked Questions (FAQs)

  • Coilcraft provides a recommended PCB land pattern in their documentation, which includes a rectangular pad with a size of 2.5 mm x 1.5 mm, and a thermal pad with a size of 2.5 mm x 2.5 mm.
  • To ensure reliability in high-temperature applications, it is recommended to derate the current rating of the inductor according to the temperature derating curve provided in the datasheet, and to ensure good thermal conduction between the inductor and the PCB.
  • Yes, the WBC4-1WLC is suitable for high-frequency applications up to 1 GHz. However, it is recommended to consult the datasheet for the inductor's frequency response and to consider the effects of skin effect and proximity effect on the inductor's performance.
  • To prevent damage during assembly, it is recommended to handle the WBC4-1WLC by the body of the inductor, avoiding touching the leads or the core. It is also recommended to use a vacuum pickup or tweezers to handle the inductor, and to avoid bending or flexing the leads.
  • Yes, the WBC4-1WLC is rated for high currents up to 1.4 A. However, it is recommended to consider the inductor's temperature rise and to ensure good thermal conduction between the inductor and the PCB to prevent overheating.
