Cosel recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
To ensure EMC, Cosel recommends using a metal enclosure, proper grounding, and shielding of the power supply and cables. Additionally, the MHFS32412 has built-in EMI filters, but external filters may be required depending on the application.
Cosel provides a derating curve in the datasheet, but for high-altitude applications, the power supply's output power should be derated by 1% per 1,000 feet above sea level to ensure reliable operation.
Yes, the MHFS32412 can be used in a redundant or parallel configuration, but it requires a specific design and synchronization scheme to ensure proper operation and to prevent oscillations. Cosel recommends consulting with their application engineers for guidance.
Cosel provides an MTBF of 550,000 hours at 40°C ambient temperature, calculated according to MIL-HDBK-217F. However, the actual MTBF may vary depending on the application, operating conditions, and quality of the components used.
