CLF7045T-471M - TDK

CLF7045T-471M Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the CLF7045T-471M?
  The recommended PCB land pattern for the CLF7045T-471M can be found in the TDK Corporation's application note or on their website. It is essential to follow the recommended land pattern to ensure proper mounting and to prevent thermal and electrical issues.
• How do I handle the CLF7045T-471M inductor during the reflow soldering process?
  During reflow soldering, it is essential to follow the recommended temperature profile to prevent damage to the inductor. The CLF7045T-471M can withstand a maximum temperature of 260°C for 30 seconds. It is also recommended to use a solder resist to prevent solder from flowing onto the inductor's body.
• What is the maximum current rating for the CLF7045T-471M inductor?
  The maximum current rating for the CLF7045T-471M inductor is 4.7A. However, it is essential to consider the inductor's temperature rise and power loss when selecting the operating current. TDK Corporation provides a current derating curve in the datasheet to help with this calculation.
• Is the CLF7045T-471M inductor suitable for high-frequency applications?
  The CLF7045T-471M inductor is designed for high-frequency applications up to 1MHz. However, its performance may degrade at higher frequencies due to the inductor's equivalent series resistance (ESR) and self-resonant frequency. It is essential to evaluate the inductor's performance in the target application frequency range.
• How do I store and handle the CLF7045T-471M inductor to prevent damage?
  The CLF7045T-471M inductor should be stored in a dry, cool place away from direct sunlight and moisture. It is also recommended to handle the inductor by the edges to prevent damage to the terminals or the body. Anti-static precautions should be taken when handling the inductor to prevent electrostatic discharge (ESD) damage.
