Product Overview
  • Bend Radius, Min 0.032 in
  • Dielectric Strength 1250 Vac
  • Heater Thickness Note 0.010" except at lead wire exit
  • Insulation PTFE
  • Insulation Note PTFE insulated (UL 1180), 12" (305 mm) long (wire gauge varies with heater). For strain relief, a silicone patch has been added to heaters.

Polyimide Film insulated (also known as Kapton ) flexible heaters are available in a variety of shapes, sizes, and wattages. Wattage ratings are 2.5, 5, or 10W/in2 at 115 or 28 V. Polyimide Film offers a high degree of resistance to chemicals. Flexible nature can fit into Intrinsic voids & can be applied very Easily

Operating temperature without PSA is -57°C to 150°C, and with PSA, these heaters operate at temperatures between -40°C and 149°C.

Typical construction consists of an etched foil element of 0.0005" or 0.0001" thickness which is encapsulated between two layers of 0.002" Polyimide Film and 0.001" FEP adhesive.

Rated 5 out of 5 by from Great adhesive and quick heatup! I bought this for a project at our company, and it does exactly what it was intended for. The adhesive sticks to what is desired very easily, and it does not want to peel off, even with lots of heat cycling. The heaters also seem to get up to temp fairly quickly. So these heaters are excellent if you want good heating times!

Rated 2 out of 5 by from Silicone is a no no in a vacuum chamber We used these Kapton heaters all over our space simulation chamber but due to the recent addition of the silicone strain relief we have to go somewhere else.

KHLVA-101-5-P we are planning to use this heater in our designing , Here by I have some query regrading the heater 1) what is the minimum input voltage and maximum input voltage required to drive this heater

Asked by: pooja
Thank you for your inquiry. You can use a maximum for 28V. There isn't designated minimum but of course anything less than the maximum will decrease the total wattage output.

1. Does the Polyimide Flexible heater p/n KHLVA-101-10-P use the same adhesive backing as the SA1-RTD? 2. What is the projected lifetime of the adhesive? 3. Is a conductive epoxy recommended in addition to the pressure sensitive adhesive?

Asked by: ericl
The two adhesives are not the same but similar. The life of the adhesive depends on the environment in which they are used. If they do not exceed the rated temperature and there are no contamination, in theory, the adhesive should last a very long time. No data to provide. You can also use a thermally conductive epoxy for additional adhesion.

About KHLVA Series, Rectangular, 28Volts, input voltage is 28V according to the spec. Are these heater available for DC volts? which range is 26.5Vdc to 32Vdc.

Asked by: Minsu
Thank you for your inquiry. DC Voltage is acceptable. 28VDC is the maximum voltage supply that can be applied.

Dear Team, We are planned to KHLVA-101-5-P in our designs ,If I give 24PWM and 0.153A to Heater, what will be the heat generated at heater side? is there any graphs related to current VS Heat generate ?? Requesting you to helps us on this !

Asked by: Pooja
Thank you for the inquiry. We do not have a way to calculate heating power in watts when a pulse driven solid state relay is used. If you apply a DC voltage at constant level then the power law and Ohm's Law can be used to calculate heating power in watts. Best regards OMEGA

Does the heater have a polarity specification or can it be wired in any direction?

Asked by: JohnME
Thank you for your inquiry. The KHLVA-205/10 is an AC load. There is no polarity when connecting an AC load.

Can the product be compressed between 2 platens under roughly 3000 lbs (around 10 MPa) of force?

Asked by: densewood
The specification for load on the Kapton Heaters is 5Kg/cm2 or about 71 PSI.
