KOA Speer TPR Temperature Protection Resistors

KOA Speer TPR Temperature Protection Resistors safely interrupt open circuits up to AC250V voltage and completely isolate the circuit after quickly fusing to the overload.  The TPR series temperature protection resistors from KOA have the pulse capability of wirewound resistors and are approved by UL1412 safety standards and are lightning surge compliant (IEC61000-4-5). Other KOA Speer TPR series features include resistance range from 2Ω-10kΩ at 5% tolerance, wide operating temperature range from -40°C to +150°C, and 1W power rating. This series is ideal for AC adapters, small size switching power supplies, and lighting equipment (LED).
