Approved Dual Function Fuse Resistors F500 Series

  • Affords protection for semiconductor devices
  • Acts as a precision wirewound resistor and a fuse
  • Allows precise control of fusing point and time lag
  • Reduces the number of discrete components required
  • Eliminates unnecessary blowing due to transient conditions
  • Eliminates fire hazard and circuit board damage due to overheated components Electrical Data IRC Style Resistance (ohms) Steady State Blow Condition I Blow Condition II Current Dissipation (watts) Current Dissipation (watts) Blow Time (T max) Current Dissipation (watts) Blow Time (T max) F501 0.2 2.2A 1 10A 20 500ms 25A 125 50ms F502 0.2 2.2A 1 10A 20 300ms 25A 125 30ms F503 0.5 1.4A 1 6A 18 10sec 15A 112 100ms F504 0.5 1.4A 1 6A 18 500ms 15A 112 50ms F505 0.5 1.4A 1 6A 18 50ms 15A 112 10ms F506 1 1.0A 1 4A 16 10sec 10A 100 100ms F507 1 1.0A 1 4A 16 500ms 10A 100 50ms F508 1 1.0A 1 4A 16 50ms 10A 100 10ms F509 2 700ma 1 3A 18 10sec 7A 98 50ms F510* 2 700ma 1 3A 18 200ms 7A 98 50ms F511* 2 700ma 1 3A 18 50ms 7A 98 10ms F512* 5 450ma 1 2A 20 200ms 4.5A 101 50ms F513* 5 400ma 0.8 1.5A 10 50ms 4.0A 80 10ms F514* 5 350ma 0.6 1.0A 5 100ms 1.4A 10 20ms F515* 10 300ma 0.9 1.2A 14 200ms 3.0A 90 10ms F516* 10 300ma 0.9 1.0A 10 100ms 1.3A 17 50ms F517* 10 200ma 0.4 600ma 3.6 100ms 900ma 8 50ms F518* 20 220ma 1 600ma 7.2 10sec 900ma 16 100ms F519* 20 220ma 1 600ma 7.2 100ms 900ma 16 50ms F520* 20 150ma 0.4 350ma 2.4 500ms 450ma 4 50ms F521* 50 140ma 1 400ma 8.0 500ms 600ma 18 50ms F522* 50 130ma 0.8 350ma 6.1 100ms 450ma 10 50ms F523* 50 80ma 0.3 200ma 2.0 200ms 240ma 2.9 50ms F524* 100 100ma 1 250ma 6.2 10sec 300ma 9.0 100ms F525* 100 80ma 0.6 200ma 4.0 200ms 250ma 6.2 50ms F526* 100 60ma 0.4 140ma 2.6 10sec 180ma 3.2 200ms F527* 200 70ma 1 200ma 8.0 10sec 250ma 12.5 100ms F528* 200 60ma 0.8 150ma 4.0 100ms 250ma 12.5 10ms *UL LISTED - Add "S" To Style Description Contact factory for specification limits beyond these listed.
