Military- Vs. Commercial-Grade Resistors: Reliability, Performance And Cost Tradeoffs

Focus:

Military-spec resistors provide an essential function in high reliability applications. However, unless you are dealing with such applications regularly, understanding what military-spec (military-grade) resistors offer compared to commercial resistors can be challenging. For example, a key distinction among military-spec resistors is whether or not they offer established reliability. This article explains in broad terms how military specifications address reliability in the manufacturing, testing, inspection and processing of resistors, and how these aspects compare with those used to produce commercial- and automotive-grade resistors. This article may help designers determine whether they actually need mil-spec resistors or can accept automotive- or commercial- grade components.

What you’ll learn:

• How to understand the differences between military-, automotive- and commercial-grade resistors
• How to determine whether mil-spec resistors are needed in an application
