Can someone please explain to me if highly sensitive space accelerometers need to be heat shielded before use in the thermosphere, if they already are heated shielded, or if their components are designed to work in those conditions?

If they don't need heat shielding can you explain how their components are still accurate in that extreme of a temperature range?

Thank you.

Typically, electronics are mounted on the inside of the spacecraft to an actively controlled isothermal panel to maintain temperatures inside a 'comfortable' range.

They're typically only shielded against radiation, not heat.
