4590-156K - Delevan

4590-156K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  API Delevan recommends a PCB layout with a symmetrical land pattern to minimize parasitic inductance and ensure optimal performance. A minimum of 0.5 mm clearance around the inductor is recommended to prevent electromagnetic interference.
• How does the inductor perform in high-temperature environments?
  The 4590-156K inductor 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 4590-156K inductor is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. API Delevan recommends using a simulation tool or consulting with their application engineers to determine the SRF for specific designs.
• Can the inductor be used in high-vibration or high-shock environments?
  The 4590-156K inductor is designed to meet the requirements of MIL-STD-202, but its performance in high-vibration or high-shock environments may vary. API Delevan recommends consulting with their application engineers to determine the inductor's suitability for specific applications.
• What is the inductor's moisture sensitivity level (MSL)?
  The 4590-156K inductor has an MSL rating of 1, indicating that it can withstand normal humidity and temperature conditions without special handling or storage requirements.
