DLW21SN211XK2L Frequently Asked Questions (FAQs)

  • Murata provides a recommended PCB land pattern in their datasheet, but it's also available on their website. The recommended land pattern is a rectangular shape with dimensions of 2.5mm x 1.6mm, with a 0.5mm hole in the center for the inductor's terminal.
  • The DLW21SN211XK2L has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management during PCB design. This includes providing adequate spacing between components, using thermal vias, and selecting a PCB material with good thermal conductivity.
  • The ESR of the DLW21SN211XK2L is not explicitly stated in the datasheet. However, according to Murata's application notes, the ESR can be estimated using the inductor's DC resistance (Rdc) and the resonant frequency (fr). A rough estimate of ESR can be calculated as ESR ≈ Rdc / (2 * π * fr * L), where L is the inductance value.
  • The DLW21SN211XK2L is designed for high-frequency applications, with a self-resonant frequency (SRF) of 100 MHz. However, it's essential to consider the inductor's impedance characteristics and ensure that it meets the specific requirements of your application. Murata provides impedance vs. frequency graphs in the datasheet to aid in this evaluation.
  • To ensure reliable soldering, follow Murata's recommended soldering conditions: peak temperature of 260°C, soldering time of 3 seconds, and a soldering iron temperature of 350°C. Additionally, use a solder with a melting point above 217°C, and ensure the PCB is clean and free of oxidation.
