CLF10040T-220M-H - TDK

CLF10040T-220M-H Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the CLF10040T-220M-H?
  The recommended PCB footprint for the CLF10040T-220M-H is a rectangular pad with a size of 10.5mm x 4.5mm, with a 1.5mm diameter hole in the center for the inductor's terminal.
• How do I ensure the inductor's reliability in high-temperature applications?
  To ensure reliability in high-temperature applications, it is recommended to derate the inductor's current rating according to the temperature derating curve provided in the datasheet, and to ensure good thermal conduction between the inductor and the PCB.
• Can I use the CLF10040T-220M-H in a high-frequency switching power supply?
  Yes, the CLF10040T-220M-H is suitable for high-frequency switching power supplies up to 1 MHz. However, it is recommended to evaluate the inductor's performance in the specific application and to consider the effects of core losses and skin effect at high frequencies.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the CLF10040T-220M-H is approximately 10 MHz, but this value can vary depending on the specific application and PCB layout.
• How do I handle the inductor's magnetic field radiation in a densely populated PCB?
  To minimize magnetic field radiation, it is recommended to keep the inductor away from sensitive components and to use shielding techniques such as mu-metal shielding or PCB shielding to contain the magnetic field.
