Application Summary AI generated

This standard specifies the detailed requirements, inspection schedules, and quality assessment procedures for directly heated positive temperature coefficient (PTC) thermistors used specifically for current limiting applications. It is applied in the electronics industry for designing and qualifying PTC components that protect circuits by abruptly increasing resistance when a fault current is detected, such as in power supplies, battery chargers, and motor starters. The "Assessment level EZ" designation defines a specific reliability and qualification testing regime for these components.
