#161213 - Wear from temperature cycling Responding to: ???'s previous message |
Regular temperature cycling can result in metal fatigue in the bond wires so you should really think twice about cycling the power like that. Another failure source is the glue that holds the silicon chip. |

automotive grade is 125C | 01/01/70 00:00 | |
You should have mentioned 150C | 01/01/70 00:00 | |
Why does it rise? | 01/01/70 00:00 | |
