DLW21SN261SQ2B Frequently Asked Questions (FAQs)

  • The recommended land pattern for the DLW21SN261SQ2B can be found in the Murata Land Pattern Recommendation document, which provides detailed information on the recommended pad layout and dimensions for optimal assembly and reliability.
  • While the datasheet specifies an operating temperature range of -40°C to +125°C, Murata recommends derating the inductor's current rating at high temperatures. For example, at 105°C, the current rating should be derated by 20%. It's essential to consult with Murata's application notes or contact their support team for specific guidance on high-temperature operation.
  • Yes, the DLW21SN261SQ2B is suitable for high-frequency applications up to several hundred kHz. However, it's crucial to consider the inductor's self-resonant frequency (SRF) and ensure that it does not coincide with the operating frequency. Murata provides SRF data in the datasheet, and engineers should consult with Murata's application notes or support team for guidance on high-frequency design.
  • Murata recommends storing the DLW21SN261SQ2B in a dry, clean environment, away from direct sunlight and moisture. The components should be stored in their original packaging or in a similar protective package to prevent mechanical damage and electrostatic discharge (ESD). It's also essential to follow proper handling procedures, such as using anti-static wrist straps and mats, to prevent ESD damage.
  • Yes, Murata recommends following specific assembly and soldering guidelines to ensure reliable operation and prevent damage to the inductor. These guidelines include using a soldering iron with a temperature of 350°C or less, avoiding excessive soldering time, and ensuring that the component is properly aligned during assembly. Consult Murata's assembly and soldering guidelines for detailed information.
