The TPR series temperature protection fusing resistors from KOA Speer safely interrupt open circuits up to 250 Vac 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 ~ +150 °C and 1 Watt power rating, TPR series fusing resistors are ideal for AC adaptors, small size switching power supplies, and lighting equipment (LED). These fusing resistors are available in 2 Ω~10kΩ¦ resistance values at 5% tolerance. TPR resistors are also lightning surge compliant (IEC61000-4-5). Lead time is 10-12 weeks.
