4590R-106K - API Delevan

4590R-106K Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 4590R-106K?
  The recommended land pattern for the 4590R-106K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
• How do I handle the 4590R-106K's thermal considerations?
  The 4590R-106K has a maximum operating temperature of 125°C. To ensure reliable operation, it's essential to provide adequate thermal relief, such as thermal vias or thermal pads, and to follow proper PCB design and layout practices to minimize thermal resistance.
• What is the self-resonant frequency (SRF) of the 4590R-106K?
  The self-resonant frequency (SRF) of the 4590R-106K is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance and capacitance values. Typically, the SRF of an inductor is around 5-10 times its operating frequency. For the 4590R-106K, the SRF is likely to be in the range of 500-1000 MHz.
• Can I use the 4590R-106K in a high-reliability or military application?
  The 4590R-106K is a commercial-grade component, but API Delevan offers equivalent military-grade components, such as the 4590R-106K-M, which meet the requirements of MIL-PRF-83446. For high-reliability or military applications, it's recommended to use the military-grade version or consult with API Delevan's application engineers for guidance.
• How do I determine the 4590R-106K's saturation current?
  The saturation current of the 4590R-106K is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance and core material properties. A general rule of thumb is to assume the saturation current is around 1.5-2 times the rated current. For the 4590R-106K, the saturation current is likely to be around 3-4 A.
