CLF12555T-220M-D - TDK

CLF12555T-220M-D Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the CLF12555T-220M-D?
  The recommended PCB land pattern for the CLF12555T-220M-D 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 3.5mm x 2.5mm, with a 0.5mm hole in the center for the inductor's terminal.
• How do I handle the inductor's thermal derating?
  The CLF12555T-220M-D has a temperature derating curve specified in the datasheet. To handle thermal derating, ensure that the inductor's operating temperature is within the specified range, and consider the derating factor when calculating the inductor's maximum current rating.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the CLF12555T-220M-D is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the SRF is around 100-200 MHz for this inductor.
• Can I use the CLF12555T-220M-D in a high-frequency application?
  While the CLF12555T-220M-D is suitable for high-frequency applications, its performance may degrade above 10 MHz due to the inductor's parasitic capacitance and resistance. It's essential to evaluate the inductor's performance in your specific application and consider alternative components if necessary.
• How do I ensure the inductor's reliability and longevity?
  To ensure the reliability and longevity of the CLF12555T-220M-D, follow proper storage and handling procedures, avoid exceeding the maximum ratings, and consider the inductor's moisture sensitivity level (MSL) during assembly and reflow soldering.
