HA3802-BLD Frequently Asked Questions (FAQs)

  • Coilcraft provides a recommended PCB land pattern in their datasheet, but it's also available on their website as a separate document. The pattern is designed to minimize thermal resistance and ensure reliable soldering.
  • The HA3802-BLD is a molded inductor, which makes it sensitive to moisture. To minimize the risk of moisture-related failures, store the components in a dry environment, and follow the recommended soldering profile to prevent moisture ingress during reflow.
  • While the datasheet specifies a maximum current rating, it doesn't explicitly state a maximum voltage rating. However, Coilcraft recommends derating the voltage to ensure reliable operation. A general rule of thumb is to limit the voltage to 80% of the maximum rated voltage to account for voltage spikes and transients.
  • The HA3802-BLD is rated for operation up to 125°C, but its performance may degrade at higher temperatures. If your application requires operation above 125°C, consider using a high-temperature version of the inductor or consulting with Coilcraft's application engineers for guidance.
  • Coilcraft provides EMI shielding options for the HA3802-BLD. Consult with their application engineers to determine the best shielding option for your specific application. Additionally, ensure proper PCB layout and grounding practices to minimize EMI radiation.
