Internal components of galvanic isolators must not exceed what?

The correct understanding pertains to why the internal components of galvanic isolators must not exceed their temperature rating. Galvanic isolators are crucial in marine applications to prevent corrosion caused by stray current in the water. These devices work by isolating components electrically while allowing certain frequencies to pass through.

Exceeding the temperature rating of any internal component can lead to failure of the device, which can compromise the safety and effectiveness of the isolator. High temperatures can cause insulation breakdown and can negatively impact the performance and longevity of the device, resulting in potential hazards such as electrical fires or failures that could lead to equipment malfunction or safety risks on board.

While voltage, power, and current ratings are all important specifications for devices to function correctly within their intended operational parameters, the temperature rating plays a decisive role in ensuring the reliability and safety of the galvanic isolators under varying environmental conditions they may face in marine settings. When components operate above their specified temperature ratings, it can lead to catastrophic failure regardless of their voltage or current capacities.
