BLM21BD222TZ1D - Murata Electronics

BLM21BD222TZ1D Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the BLM21BD222TZ1D?
  The recommended land pattern for the BLM21BD222TZ1D is a rectangular pad with a size of 2.5mm x 1.6mm, with a non-solder mask defined (NSMD) pad shape. This can be found in the Murata Land Pattern Recommendation document.
• How do I handle the BLM21BD222TZ1D's thermal considerations?
  The BLM21BD222TZ1D has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to consider thermal management by providing adequate heat dissipation, using thermal vias, and keeping the component away from heat sources.
• What is the self-resonant frequency (SRF) of the BLM21BD222TZ1D?
  The self-resonant frequency (SRF) of the BLM21BD222TZ1D is not explicitly stated in the datasheet. However, based on similar inductors from Murata, the SRF is typically in the range of 100-200 MHz. It's recommended to consult with Murata's application engineers or perform your own measurements to determine the SRF for your specific application.
• Can I use the BLM21BD222TZ1D in a high-frequency application?
  While the BLM21BD222TZ1D is suitable for high-frequency applications, its performance may degrade above 100 MHz. It's essential to evaluate the inductor's impedance characteristics and ensure it meets your specific application requirements. You may need to consider other inductor options or consult with Murata's application engineers for high-frequency applications.
• How do I ensure the BLM21BD222TZ1D meets my application's impedance requirements?
  To ensure the BLM21BD222TZ1D meets your application's impedance requirements, you should evaluate the inductor's impedance characteristics using impedance analyzers or simulation tools like SPICE models. This will help you determine the inductor's suitability for your specific application.
