TDK-Lambda recommends a multi-layer PCB with a solid ground plane and a thermal pad connected to a heat sink or a metal chassis for efficient heat dissipation. A minimum of 2oz copper thickness is recommended for the PCB.
To ensure EMC, TDK-Lambda recommends using a metal enclosure, keeping the DC input and output cables as short as possible, and using EMI filters or shielding on the input and output lines.
The derating curve is not explicitly provided in the datasheet, but TDK-Lambda recommends derating the output power by 2.5% per degree Celsius above 40°C to ensure reliable operation.
Yes, the CSW65-18/D can be used in a redundant or parallel configuration, but it requires additional external circuitry and careful design consideration to ensure proper operation and fault tolerance.
The MTBF of the CSW65-18/D is not explicitly stated in the datasheet, but TDK-Lambda provides a reliability report upon request, which includes the MTBF calculation based on MIL-HDBK-217F.
