BLM31KN102SZ1L - Murata Electronics

BLM31KN102SZ1L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM31KN102SZ1L?
  The recommended land pattern for the BLM31KN102SZ1L is a rectangular pad with a size of 3.5mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape.
• How do I handle the BLM31KN102SZ1L's sensitivity to temperature?
  The BLM31KN102SZ1L's inductance value changes with temperature. To minimize the impact, use a temperature-stable PCB material, and consider using a thermally-conductive interface material between the inductor and the PCB.
• What is the maximum current rating for the BLM31KN102SZ1L?
  The maximum current rating for the BLM31KN102SZ1L is 1.8A, but this value can be affected by the operating frequency, temperature, and other factors. Always check the inductor's temperature rise and saturation current in your specific application.
• Can I use the BLM31KN102SZ1L in a high-frequency application?
  Yes, the BLM31KN102SZ1L is suitable for high-frequency applications up to 1 GHz. However, be aware that the inductor's impedance and loss characteristics will change with frequency, so ensure you evaluate its performance in your specific application.
• How do I ensure the BLM31KN102SZ1L is properly soldered to the PCB?
  To ensure proper soldering, use a soldering iron with a temperature of 350°C to 370°C, and apply a solder paste with a melting point of 217°C to 221°C. Avoid applying excessive force or pressure during soldering.
