VLS252012ET-4R7M-CA - TDK

VLS252012ET-4R7M-CA Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the VLS252012ET-4R7M-CA 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 2.5mm x 1.5mm, with a 0.5mm hole in the center for the inductor's terminal.
• How do I handle the inductor's thermal derating?
  The thermal derating of the VLS252012ET-4R7M-CA is typically handled by reducing the maximum current rating as the ambient temperature increases. TDK Corporation provides a thermal derating curve in the datasheet, which shows the maximum current rating at different temperatures. Engineers should ensure that their design stays within the recommended current rating at the expected operating temperature.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the VLS252012ET-4R7M-CA 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 of this inductor is around 100-200 MHz. However, it's recommended to consult with TDK Corporation or perform measurements to determine the exact SRF for a specific application.
• Is the inductor suitable for high-frequency applications?
  The VLS252012ET-4R7M-CA is designed for high-frequency applications, with a recommended operating frequency range of up to 100 MHz. However, its performance at higher frequencies may be affected by the inductor's parasitic capacitance and resistance. Engineers should evaluate the inductor's performance in their specific application and consider using other inductors or components if necessary.
• What is the inductor's moisture sensitivity level (MSL)?
  The moisture sensitivity level (MSL) of the VLS252012ET-4R7M-CA is typically MSL 1, which means it can withstand a maximum of 30°C/60%RH for 168 hours. This information may not be explicitly stated in the datasheet, but it can be found in the TDK Corporation's packaging and handling guidelines.
