Traditional Wire Wound Heater/Resistors

Large and bulky 3-dimensional shapes cause issues for designers. These designs use excessive amounts of space to accommodate the wire, central core and mounting hardware. Heat transfer is poor due to the difficulty in thermally coupling the cylindrical shape to standard heat sinks. High resistances can only be achieved through excessively long wires or through extremely thin wires-neither of which is desirable. The majority of wound resistors are spiral wound and add inductance to the circuit that may be unacceptable. Inductance be reduced by special winding techniques but this adds cost to the resistor.

Thick Film Heaters and Resistors.

Thick film heaters and resistors are generally flat 2-dimensional shapes as thin as 0.010” thick, which offer a low profile. This minimizes the space requirements and is inherently better for thermal coupling to flat heat sinks, circuit boards and bulk heads. The thick film pastes come in a variety of resistance values so resistors from less than 1 to many Giga Ohms can be produced. This variety also allows tailoring of the resistance traces to accommodate the surface area available and optimize the amount of thermal coupling to transfer heat. The printed pattern allows opportunities to reduce/eliminate added electrical inductance inherent in wound resistors that may be unacceptable.

We have worked with the team at Thick Film Technologies on several international consulting projects and have found them to be professional, responsive and effective. We intend to maintain and expand our relationship and would not hesitate recommending them to anyone.
We enjoy working with TFT because they are very responsive to technical inquiries and are proactive in finding solutions to design challenges, even ones that we have not foreseen — TFT has always made me feel that we are working together on the same team. In addition, they are very conscientious about delivery time and the end product is of very high quality.
