1111SQ-43NJEC Frequently Asked Questions (FAQs)

  • Coilcraft provides a recommended land pattern for the 1111SQ-43NJEC in their documentation, which can be found on their website. The recommended land pattern is designed to ensure optimal performance and reliability of the inductor.
  • The 1111SQ-43NJEC is rated for operation up to 125°C, but it's recommended to derate the current rating at higher temperatures. Coilcraft provides a temperature derating curve in their documentation, which can be used to determine the maximum current rating at a given temperature.
  • To prevent damage during PCB assembly, it's recommended to handle the 1111SQ-43NJEC by the body of the component, rather than the leads. This will help prevent bending or damaging the leads. Additionally, it's recommended to use a vacuum pickup or tweezers to handle the component, rather than touching it with bare hands.
  • The self-resonant frequency (SRF) of the 1111SQ-43NJEC is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Coilcraft provides an SRF calculator on their website, which can be used to estimate the SRF of the 1111SQ-43NJEC.
  • The 1111SQ-43NJEC is designed to withstand moderate vibration, but it's recommended to evaluate the component's performance in the specific vibration environment. Coilcraft provides vibration testing data for their inductors, which can be used to determine the component's suitability for a given application.
