Product Description
Product Overview
The KOA HPC series ceramic resistors are designed for anti-pulse surge applications, offering superior resistance to inrush current and active discharge. These resistors provide higher reliability against disconnection compared to wirewound and film resistors, meeting EU RoHS requirements. They are non-inductive and AEC-Q200 tested, making them suitable for demanding environmental applications. The derating curve illustrates power reduction at ambient temperatures of 40C and above.
