TK/TN Series

 

20 and 15 Watt TO-220 Style Thick and Thin Film Resistors
RoHS Compliant

http://www.ohmite.com/catalog/images/tktn-img.jpghttp://www.ohmite.com/catalog/images/tktn-dim.gifRoHS compliant

Ohmite is proud to introduce the newest addition to our family of Heat Sinkable Power Resistors. The TK/TN Series offers 3 major advances over existing TO-220 products:

  • Low Resistance Values down to 0.03 ohms for current sense applications
  • Low Cost
  • Thin Film Construction is the first Thin Film power resistor in heatsinkable packaging on the market.

Why Thin Film? Thin film technology offers the following performance advantages:

  • Extremely stable (low TCR)
  • Low Noise (parasitic capacitance and resistance)
  • Excellent High Frequency Performance
  • High Accuracy (tight tolerances)

SPECIFICATIONS

Material

  • Resistive element: Thick or thin film chip resistor
  • Leads: Tin plated copper (100Sn)
  • Case: Ryton
  • Heatsink plate: Black anodized aluminum
