VLS252010CX-4R7M - TDK

VLS252010CX-4R7M Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the VLS252010CX-4R7M 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 VLS252010CX-4R7M 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 can use this curve to determine the maximum current rating for their specific application.
• What is the inductor's self-resonant frequency?
  The self-resonant frequency of the VLS252010CX-4R7M is typically not specified in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Engineers can use simulation tools or consult with TDK Corporation's application engineers to determine the self-resonant frequency for their specific application.
• How do I ensure the inductor's reliability in high-vibration environments?
  To ensure the reliability of the VLS252010CX-4R7M in high-vibration environments, engineers can use a variety of techniques, such as using a secure mounting method, adding a vibration-absorbing material, and selecting a component with a high vibration rating. TDK Corporation also provides vibration testing data for their inductors, which can be used to determine the component's reliability in specific applications.
• What is the inductor's equivalent series resistance (ESR)?
  The equivalent series resistance (ESR) of the VLS252010CX-4R7M is typically not specified in the datasheet, but it can be estimated using the inductor's DC resistance and the frequency of operation. Engineers can use simulation tools or consult with TDK Corporation's application engineers to determine the ESR for their specific application.
