CLF7045T-4R7N - TDK

CLF7045T-4R7N Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the CLF7045T-4R7N?
  The recommended land pattern for the CLF7045T-4R7N can be found in the TDK Corporation's application note or on their website. It typically includes a rectangular pad with a size of around 4.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the inductor's terminal.
• How do I handle the CLF7045T-4R7N's thermal considerations?
  The CLF7045T-4R7N has a maximum operating temperature of 125°C. To handle thermal considerations, ensure good airflow around the inductor, avoid overheating nearby components, and consider using a heat sink or thermal interface material if necessary.
• What is the self-resonant frequency of the CLF7045T-4R7N?
  The self-resonant frequency of the CLF7045T-4R7N is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, it falls in the range of 100-200 MHz.
• Can I use the CLF7045T-4R7N in a high-frequency application?
  While the CLF7045T-4R7N is suitable for high-frequency applications, its performance may degrade above 100 MHz due to its self-resonant frequency and parasitic capacitance. It's essential to evaluate the inductor's performance in your specific application and consider using a more suitable inductor if necessary.
• How do I ensure the CLF7045T-4R7N is properly soldered?
  To ensure proper soldering, follow the recommended soldering profile, use a solder with a melting point below 260°C, and avoid applying excessive heat or force to the inductor. Also, ensure the inductor is properly aligned with the land pattern and the solder fillet is smooth and shiny.
