BLM18HD102SZ1D - Murata Electronics

BLM18HD102SZ1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM18HD102SZ1D?
  The recommended land pattern for the BLM18HD102SZ1D is a rectangular pad with a size of 3.2mm x 2.5mm, with a non-solder mask defined (NSMD) pad shape. The pad should be centered on the component and have a solder mask opening of 2.2mm x 1.5mm.
• How do I handle the BLM18HD102SZ1D's sensitivity to soldering temperature?
  To minimize the risk of damage, it's recommended to follow the soldering temperature profile specified in the Murata datasheet, which is 260°C for 10 seconds or less. Additionally, use a soldering iron with a temperature control function and avoid applying excessive heat or pressure during the soldering process.
• Can I use the BLM18HD102SZ1D in a high-frequency application?
  Yes, the BLM18HD102SZ1D 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 does not coincide with the operating frequency of your application. The SRF of the BLM18HD102SZ1D is approximately 1.2 GHz.
• How do I determine the optimal operating current for the BLM18HD102SZ1D?
  The optimal operating current for the BLM18HD102SZ1D depends on the specific application and operating conditions. As a general guideline, the rated current of the inductor is 1.8 A, and the maximum permissible current is 2.5 A. It's recommended to derate the current based on the ambient temperature and other environmental factors to ensure reliable operation.
• Is the BLM18HD102SZ1D compatible with lead-free soldering processes?
  Yes, the BLM18HD102SZ1D is compatible with lead-free soldering processes. Murata has qualified the component for use with lead-free solders, such as SnAgCu, and it meets the requirements of the RoHS directive.
