VLF10045T-2R2N7R4 - TDK

VLF10045T-2R2N7R4 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the VLF10045T-2R2N7R4 inductor 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 4.5mm x 2.5mm, with a 0.5mm clearance around the pad.
• How do I handle the inductor's thermal derating?
  The thermal derating of the VLF10045T-2R2N7R4 inductor is typically handled by reducing the current rating of the inductor as the ambient temperature increases. The derating curve can be found in the datasheet or in TDK's application notes. As a general rule, the current rating is reduced by 1.5% to 2% per degree Celsius above 70°C.
• What is the inductor's self-resonant frequency (SRF)?
  The self-resonant frequency (SRF) of the VLF10045T-2R2N7R4 inductor 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 100-150 MHz.
• Can I use this inductor in a high-frequency application?
  The VLF10045T-2R2N7R4 inductor is designed for low-frequency applications up to 100 kHz. While it may be possible to use it in higher-frequency applications, its performance may degrade due to the inductor's parasitic capacitance and resistance. It's recommended to consult with TDK Corporation or use a more suitable inductor for high-frequency applications.
• How do I ensure the inductor's reliability in a high-reliability application?
  To ensure the reliability of the VLF10045T-2R2N7R4 inductor in a high-reliability application, follow proper storage and handling procedures, use a robust PCB design and layout, and ensure that the inductor is operated within its specified ratings. Additionally, consider using a more reliable inductor with a higher temperature rating and a longer lifespan.
