KOA Speer announced its TPR Series temperature protection fusing resistors. The resistors safely interrupt open circuits up to AC250 V voltage and completely isolate the circuit after quickly fusing to the overload. These fusing resistors feature the pulse capability of wirewound resistors and are approved by UL1412 safety standards. With a wide operating temperature range of -40°C to approximately +150°C and 1 W power rating, TPR Series fusing resistors are suitable for AC adaptors, small size switching power supplies, and lighting equipment (LED). These fusing resistors are available in 2 Ω to approximaterly 10-kΩ resistance values at 5 percent tolerance. The resistors are also lightning surge compliant (IEC61000-4-5).
