BLM15PX331SZ1D - Murata Electronics

BLM15PX331SZ1D Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the BLM15PX331SZ1D?
  Murata provides a recommended PCB land pattern in their 'Chip Inductors for General Use' application note (PDF). The recommended land pattern is a rectangular shape with dimensions of 1.5mm x 0.8mm, with a 0.5mm diameter hole in the center for the component's terminal.
• How do I handle the BLM15PX331SZ1D's thermal considerations?
  The BLM15PX331SZ1D has a maximum operating temperature of 125°C. To ensure reliable operation, keep the component away from heat sources, use a sufficient copper area for heat dissipation, and consider using thermal vias or a thermal pad on the PCB.
• What is the BLM15PX331SZ1D's self-resonant frequency (SRF)?
  The SRF of the BLM15PX331SZ1D is not explicitly stated in the datasheet. However, according to Murata's inductor selection guide, the SRF of a similar inductor (BLM15PX331SZ1) is around 150 MHz. It's recommended to consult with Murata's support team or perform your own measurements to determine the SRF of the BLM15PX331SZ1D.
• Can I use the BLM15PX331SZ1D in a high-frequency application (e.g., above 100 MHz)?
  While the BLM15PX331SZ1D is suitable for high-frequency applications, its performance may degrade above 100 MHz due to the inductor's equivalent series resistance (ESR) and parasitic capacitance. It's recommended to evaluate the component's performance in your specific application and consider using a more suitable inductor for high-frequency designs.
• How do I ensure the BLM15PX331SZ1D's reliability in a high-reliability application?
  To ensure the BLM15PX331SZ1D's reliability, follow Murata's recommended storage and handling guidelines, use a robust PCB design with adequate clearance and creepage distances, and consider implementing a robust assembly process with proper soldering and cleaning procedures.
