CUI 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.
The PBO-5C-12 has built-in input voltage transient protection, but it's recommended to add external transient voltage suppressors (TVS) or metal-oxide varistors (MOVs) to ensure protection against high-energy transients and spikes.
The maximum cable length for the output connectors is 1 meter, and CUI recommends using shielded cables with a minimum of 18 AWG wire size to minimize voltage drop and electromagnetic interference (EMI).
The PBO-5C-12 is designed for operation up to 5,000 meters (16,400 feet) and temperatures up to 80°C. For higher altitudes or temperatures, derating may be necessary, and CUI recommends consulting with their application engineers for specific guidance.
CUI recommends using EMI filters and shielding to meet the relevant electromagnetic compatibility (EMC) standards. The PBO-5C-12 has a built-in EMI filter, but additional external filtering may be required depending on the specific application and environment.
