VLM10555T-1R2M100-3 - TDK

VLM10555T-1R2M100-3 Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this inductor?
  The recommended land pattern for the VLM10555T-1R2M100-3 can be found in the TDK Corporation's application note or footprint library. It typically includes a rectangular pad with a size of around 1.2mm x 1.4mm, with a 0.3mm hole in the center for the inductor's terminal.
• How do I handle the inductor's thermal derating?
  The thermal derating of the VLM10555T-1R2M100-3 inductor 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 VLM10555T-1R2M100-3 inductor is not explicitly stated in the datasheet. However, based on the inductor's construction and materials, the SRF is typically in the range of 100-200 MHz. Engineers should be aware of the SRF when designing high-frequency circuits to avoid unwanted resonances.
• Can I use this inductor in a high-vibration environment?
  The VLM10555T-1R2M100-3 inductor is designed to meet the vibration requirements of IEC 60068-2-6, which includes vibration testing up to 10G. However, engineers should still perform their own vibration testing and analysis to ensure that the inductor meets the specific requirements of their application.
• How do I ensure the inductor's reliability in a humid environment?
  The VLM10555T-1R2M100-3 inductor is designed to meet the moisture resistance requirements of IEC 60068-2-78. To ensure reliability in a humid environment, engineers should follow proper storage and handling procedures, and consider applying a conformal coating to the PCB. Additionally, they should ensure that the inductor is operated within its recommended temperature and humidity ranges.
