4922R-28L - API Delevan

4922R-28L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 4922R-28L?
  The recommended land pattern for the 4922R-28L is a rectangular pad with a minimum size of 50 mils x 30 mils, with a non-solder mask defined (NSMD) pad to ensure proper solder flow and to prevent solder from flowing onto the adjacent pads.
• Can the 4922R-28L be used in high-temperature applications?
  The 4922R-28L is rated for operation up to 155°C, but derating is required for temperatures above 125°C. It's essential to consult the temperature derating curve in the datasheet to ensure the inductor can handle the specific application's temperature requirements.
• How do I handle the 4922R-28L's magnetic shielding requirements?
  The 4922R-28L is a shielded inductor, and proper shielding is crucial to minimize electromagnetic interference (EMI). Ensure that the inductor is placed on a solid copper plane or a shielded area on the PCB, and follow the manufacturer's recommended shielding guidelines.
• What is the maximum current rating for the 4922R-28L?
  The maximum current rating for the 4922R-28L is 2.8 A, but this value can vary depending on the operating frequency and temperature. Always consult the datasheet's current rating vs. frequency and temperature graphs to ensure the inductor can handle the specific application's current requirements.
• Can the 4922R-28L be used in high-frequency applications?
  The 4922R-28L is designed for high-frequency applications up to 1 GHz, but its performance may degrade at higher frequencies. It's essential to consult the datasheet's impedance vs. frequency graph to ensure the inductor meets the specific application's high-frequency requirements.
