BLM15HD102BH1D - Murata Electronics

BLM15HD102BH1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM15HD102BH1D?
  The recommended land pattern for the BLM15HD102BH1D is a rectangular pad with a size of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the pin. The land pattern should be designed to ensure good solderability and thermal dissipation.
• How do I handle the BLM15HD102BH1D's high current rating during PCB design?
  To handle the high current rating of the BLM15HD102BH1D, ensure that the PCB traces and vias are designed to handle the maximum current rating of 15A. Use thick copper traces (at least 1 oz) and multiple vias to reduce resistance and thermal stress. Also, consider using a heat sink or thermal pad to dissipate heat generated by the inductor.
• What is the operating temperature range for the BLM15HD102BH1D?
  The operating temperature range for the BLM15HD102BH1D is -40°C to +125°C. However, the inductor's characteristics, such as inductance and DC resistance, may vary depending on the temperature. Ensure that your design takes into account these variations to ensure reliable operation.
• How do I select the correct inductor for my specific application?
  To select the correct inductor, consider factors such as the operating frequency, current rating, inductance value, and physical size. The BLM15HD102BH1D is suitable for high-frequency applications, such as DC-DC converters, filters, and resonant circuits. Ensure that the inductor's characteristics match your application's requirements.
• What is the equivalent series resistance (ESR) of the BLM15HD102BH1D?
  The equivalent series resistance (ESR) of the BLM15HD102BH1D is not explicitly stated in the datasheet. However, Murata provides an ESR value of 10.5mΩ at 100kHz in the inductor's characteristic graph. This value can be used as a reference for your design, but it's recommended to consult with Murata or perform your own measurements for accurate ESR values.
