Reporting question for Fiberboard - Vulcanized, 3" x 15", .062" Thick

Product:
Fiberboard - Vulcanized, 3" x 15", .062" Thick

Question:
What operating temperatures can this product handle? Can this be used as a base for resistor assemblies?

Answer:
I always use a spacer beneath all passive components when mounting using eyelets. This will keep components elevated from the board which can only help dissipate heat. It's a good practice to follow regardless of temperature ratings. -DaveC
