Wattage Estimation Tool

This tool provides an estimation of the needed wattage rating of a flexible heater to achieve the results of entered values. This is approximate and is intended to assist engineers and designers in thermal analysis calculations. Users should use this information as a guide and should verify results of the thermal package in their own system.


Designers can quickly flow through the nine-step process by entering key information fields that include:

  • Minimal starting temperature
  • Heat sink material
  • Heat sink mass
  • Desired Peak Temperature
  • Desired time to go from minimum temp to maximum temperature
  • Air flow
  • Surface area


Complete the form to begin using the tool. You can use the tool as many times as desired upon entry.
