CMT1-1.4-12L - COILCRAFT

CMT1-1.4-12L Frequently Asked Questions (FAQs)

• What is the recommended PCB pad layout for the CMT1-1.4-12L?
  Coilcraft provides a recommended PCB pad layout in their application notes, which includes a land pattern with a 1.4 mm x 1.4 mm pad size and a 0.5 mm x 0.5 mm via hole.
• How do I handle the CMT1-1.4-12L's high self-resonant frequency in my design?
  To minimize the impact of the high self-resonant frequency, use a series resistor to dampen the resonance, or use a parallel capacitor to tune out the resonance. Additionally, consider using a shielded inductor or a different inductor with a lower self-resonant frequency.
• What is the maximum operating temperature range for the CMT1-1.4-12L?
  The maximum operating temperature range for the CMT1-1.4-12L is -40°C to +125°C, with a derating of 1.4% per degree Celsius above 80°C.
• How do I ensure the CMT1-1.4-12L meets my design's electromagnetic interference (EMI) requirements?
  Use a shielded inductor or add a shield around the inductor to reduce EMI. Additionally, consider using a common-mode choke or a ferrite bead in series with the inductor to filter out high-frequency noise.
• What is the recommended storage and handling procedure for the CMT1-1.4-12L?
  Store the CMT1-1.4-12L in a dry, cool place, away from direct sunlight and moisture. Handle the components by the body, not the leads, to prevent damage. Use anti-static packaging and handling procedures to prevent electrostatic discharge (ESD) damage.
