VLS3012ET-470M - TDK

VLS3012ET-470M Frequently Asked Questions (FAQs)

• What is the recommended PCB footprint for the VLS3012ET-470M?
  The recommended PCB footprint for the VLS3012ET-470M is a rectangular pad with dimensions of 3.2mm x 2.5mm, with a 1.1mm diameter hole in the center for the inductor's terminal.
• How do I handle the inductor's thermal considerations?
  The VLS3012ET-470M has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal pad if the inductor will be operating near its maximum temperature rating.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the VLS3012ET-470M is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's physical characteristics and similar products from TDK Corporation.
• Can I use the VLS3012ET-470M in a high-frequency switching regulator?
  Yes, the VLS3012ET-470M is suitable for high-frequency switching regulators due to its low core loss and high SRF. However, ensure that the inductor's maximum current rating and saturation characteristics are considered in the design.
• How do I determine the inductor's saturation current?
  The saturation current of the VLS3012ET-470M can be determined by measuring the inductor's inductance versus current using an impedance analyzer or a similar test setup. The saturation current is typically defined as the current at which the inductor's inductance drops to 70-80% of its nominal value.
