IC Grade
Grade | Operating temperature | |
---|---|---|
Min | Max | |
Commercial | 0°C / 32°F | 70°C / 158°F |
Industrial | -40°C / 40°F | 85°C / 185°F |
Military | -55°C / -67°F | 125°C / 257°F |
The integrated circuit grade or temperature grade (or rating) is a method of classifying ICs based on their operating temperature - typically based on the intended purpose of a particular chip .
Components usually fall into one of four categories: commercial, industrial, automative, and military. While commercial-grade are the most commonly sold parts, over the years demand from the military, aerospace, automotive, and exploration (oil/gass) introduced the need for additional rates to satisfy those harsher operating conditions.
Do to their limited availability, military parts are usually much harder to come by - sometimes impossible if a manufacturer has no demand for them.
