These devices are often used in computer power supplies, largely due to the PC 97 standard (which recommends a sealed PC that the user never has to open), and in aerospace/nuclear applications where replacement is difficult.
Disse enheder anvendes typisk i computer strømforsyninger eller bundkort grundet PC 97-standarden (hvilket anbefaler en forseglet PC som brugeren ikke behøver at åbne) og i luftfart/kernekraft anvendelser hvor udskiftning er vanskeligt.
