Electronic components and grade introduction

Electronic components are the general term for components and devices. It is a component of electronic components and small machines and instruments. It is often composed of several parts and can be used in similar products. Often refers to electrical appliances, radio, instrumentation and other industrial parts, such as capacitance, transistor, spring, spring and other sub-devices.

I. Composition of electronic components

Electronic components consist of two major components: electronic components and electronic components.

Common electronic components are generally in accordance with the use of temperature, radiation, interference and so on to grade.

Commercial, industrial, automotive, military, aerospace.

Electronic components and grade introduction

Commercial grade - temperature: 0℃ ~ +70℃, common on the market, often traded that, computers, mobile phones, household appliances can see are basically commercial grade, the cheapest, the most common and practical.

Industrial grade - temperature: -40℃ ~ +85℃, slightly lower than the military grade, price second, precision is also slightly worse.

Automotive industrial grade - temperature: -40℃ ~ 125℃, mainly used in the automotive precision components, the use of higher temperature requirements, more expensive than industrial grade.

Military grade - temperature: -55℃ ~ +150℃, mainly used in missiles, aircraft, tanks, aircraft carriers and other military fields, military electronic components, any part out, are the most advanced, leading process, expensive, high precision.

Aerospace grade - temperature: -55℃ ~ +150℃, aerospace grade components are the highest level of components, mainly used in rockets, spacecraft, satellites and other aerospace fields, the use of temperature is the same as military grade, but on the basis of military grade increase radiation resistance, anti-interference function.
