M83446/39-26F Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  API Delevan recommends a PCB layout with a minimum of 0.5 mm clearance around the inductor and a land pattern with a 1.5 mm diameter pad for the terminals. A symmetrical layout and a solid ground plane are also recommended to minimize electromagnetic interference.
• How does the inductor perform in high-temperature environments?
  The M83446/39-26F is rated for operation up to 125°C, but its performance may degrade at higher temperatures. API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the M83446/39-26F is not explicitly stated in the datasheet, but it can be estimated to be around 100-150 MHz based on the inductor's physical characteristics and materials. However, this value may vary depending on the specific application and PCB layout.
• Can the inductor be used in high-vibration or high-shock environments?
  The M83446/39-26F is designed to meet the requirements of MIL-PRF-83446, which includes vibration and shock testing. However, it's essential to consult with API Delevan or a qualified engineer to ensure the inductor meets the specific requirements of your application.
• What is the inductor's moisture sensitivity level (MSL)?
  The M83446/39-26F has an MSL rating of 1, which means it can withstand normal humidity and temperature conditions without special handling or storage requirements.
