PM3602-100-RC - Bourns

PM3602-100-RC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns provides a recommended PCB layout and land pattern in their application notes and design guides. It's essential to follow these guidelines to ensure optimal performance, low EMI, and high reliability.
• How do I ensure the inductor's self-resonant frequency (SRF) doesn't affect my circuit's performance?
  To minimize the impact of SRF, ensure the inductor is used below its SRF, and consider adding a decoupling capacitor to filter out high-frequency noise. Additionally, use a shielded inductor or add a shield to reduce EMI.
• What is the maximum allowable current for this inductor, and how does it affect its temperature rating?
  The maximum allowable current is dependent on the inductor's temperature rating. For the PM3602-100-RC, the maximum current rating is 10.4A at 40°C. Exceeding this current may reduce the inductor's lifespan and increase its temperature.
• How do I choose the correct inductor value for my specific application?
  Select an inductor value based on your application's specific requirements, such as the desired inductance, current rating, and frequency of operation. Consult Bourns' inductor selection guides and application notes for guidance.
• What are the thermal considerations for this inductor, and how does it affect its reliability?
  The PM3602-100-RC has a maximum operating temperature of 125°C. Ensure proper thermal management by providing adequate airflow, using a heat sink if necessary, and avoiding excessive current or voltage stress.
