BLM18KG101TZ1D - Murata Electronics

BLM18KG101TZ1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM18KG101TZ1D?
  The recommended land pattern for the BLM18KG101TZ1D is a rectangular pad with a size of 2.5mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape. This is specified in the Murata datasheet and is recommended to ensure proper soldering and thermal performance.
• Can I use the BLM18KG101TZ1D in a high-temperature environment?
  The BLM18KG101TZ1D is rated for operation up to 125°C, but it's recommended to derate the current rating above 85°C. It's essential to consider the temperature coefficient of inductance and the self-resonant frequency when operating in high-temperature environments.
• How do I handle the BLM18KG101TZ1D during PCB assembly to prevent damage?
  To prevent damage, handle the BLM18KG101TZ1D by the edges, avoid touching the component body, and use an anti-static wrist strap or mat. Also, ensure that the PCB is clean and dry before assembly, and avoid applying excessive force or pressure during soldering.
• What is the equivalent series resistance (ESR) of the BLM18KG101TZ1D?
  The ESR of the BLM18KG101TZ1D is not explicitly stated in the datasheet, but it can be estimated based on the DC resistance (Rdc) and the inductance value. A rough estimate of ESR can be calculated as ESR ≈ Rdc / (2 * π * f * L), where f is the operating frequency and L is the inductance value.
• Can I use the BLM18KG101TZ1D in a switching regulator application?
  Yes, the BLM18KG101TZ1D is suitable for use in switching regulator applications due to its high current rating and low DC resistance. However, it's essential to consider the inductor's saturation current, core loss, and self-resonant frequency to ensure stable operation and minimize losses.
