LQB15NNR27J10D - Murata Electronics

LQB15NNR27J10D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for LQB15NNR27J10D?
  The recommended land pattern for LQB15NNR27J10D is a rectangular pad with a size of 1.5mm x 1.5mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a clearance of at least 0.2mm from the component body.
• How do I handle the LQB15NNR27J10D's sensitivity to soldering temperature?
  To minimize the risk of damage, it's recommended to follow the recommended soldering temperature profile, which is 260°C for 10 seconds or less. It's also important to use a soldering iron with a low thermal mass and to avoid applying excessive heat or pressure during the soldering process.
• Can I use the LQB15NNR27J10D in a high-frequency application?
  Yes, the LQB15NNR27J10D is suitable for high-frequency applications up to 1 GHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that it's not operated near the SRF to avoid unwanted resonances and losses.
• How do I determine the LQB15NNR27J10D's equivalent series resistance (ESR)?
  The ESR of the LQB15NNR27J10D can be determined by measuring the impedance of the inductor at a specific frequency using an impedance analyzer or a network analyzer. The ESR is typically measured at 100 kHz or 1 MHz, and the value can be found in the datasheet or by contacting Murata's technical support.
• Is the LQB15NNR27J10D compatible with lead-free soldering?
  Yes, the LQB15NNR27J10D is compatible with lead-free soldering processes. Murata uses a lead-free termination material that meets the requirements of the RoHS directive and is compatible with lead-free soldering temperatures up to 260°C.
