Fusing Resistors (TPR Series) | KOA Speer

TPR series resistors safely interrupt open circuits up to AC250V 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 ~ +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 ~10k Ω  resistance values at 5% tolerance. TPR resistors are also lightning surge compliant (IEC61000-4-5).

 

Features & Benefits:

  • Quickly fuses to the overload
  • Circuit is completely isolated after fusing
  • Lightning surge test (IEC61000-4-5) effective

Applications:

  • AC adaptors
  • Small size switching power supplies
  • Lighting equipment (LED)
