1025R-90K Frequently Asked Questions (FAQs)

  • API Delevan recommends a PCB land pattern with a minimum pad size of 0.045 inches (1.14 mm) and a maximum pad size of 0.055 inches (1.4 mm) to ensure proper soldering and thermal management.
  • The 1025R-90K is rated for operation up to 155°C, but its inductance and resistance may vary with temperature. API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
  • The SRF of the 1025R-90K is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout. Engineers should consider this when designing high-frequency circuits.
  • Yes, the 1025R-90K meets the requirements of MIL-PRF-83446 and is suitable for use in high-reliability and military applications. However, engineers should consult with API Delevan for specific screening and testing requirements.
  • The 1025R-90K is designed to handle high-current surges up to 10 times its rated current for short durations (typically < 10 ms). However, repeated or prolonged exposure to high-current surges may affect the inductor's reliability and lifespan.
