8532R-28L - API Delevan

8532R-28L Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 8532R-28L?
  API Delevan provides a recommended PCB land pattern in their application notes, which can be found on their website. The recommended land pattern is a rectangular pad with dimensions of 0.25 inches x 0.15 inches (6.4 mm x 3.8 mm) with a 0.05 inch (1.3 mm) hole in the center for the inductor's lead.
• How do I handle the inductor's thermal derating?
  The 8532R-28L has a temperature rating of 130°C. To handle thermal derating, you should ensure that the inductor's operating temperature is below the rated temperature. You can use thermal simulation tools or consult with a thermal expert to determine the inductor's temperature rise in your specific application.
• What is the inductor's self-resonant frequency (SRF)?
  The SRF of the 8532R-28L is not explicitly stated in the datasheet. However, according to API Delevan's application notes, the SRF can be estimated using the following formula: SRF (MHz) = 1000 / (π * √(L * C)), where L is the inductance and C is the equivalent series capacitance. For the 8532R-28L, the SRF is approximately 23 MHz.
• Can I use the 8532R-28L in a high-reliability or military application?
  The 8532R-28L is a commercial-grade inductor, but API Delevan offers equivalent military-grade inductors, such as the 8532R-28M, which meets the requirements of MIL-PRF-83446. If you need a high-reliability or military-grade inductor, you should contact API Delevan or a authorized distributor for more information.
• How do I ensure the inductor's reliability in a high-vibration environment?
  To ensure the inductor's reliability in a high-vibration environment, you should follow API Delevan's recommended mounting and soldering procedures. Additionally, you can consider using a potting compound or conformal coating to secure the inductor and prevent mechanical stress. Consult with a mechanical engineer or a reliability expert for more guidance.
