Custom Thick Film Heaters

(Ohmite's thick film resistors can be effectively used as heaters due to their ability to convert electrical energy into heat energy. When an electric current flows through the thick film resistor, electrical resistance causes the current to dissipate energy in the form of heat. The substrate on which the thick film resistor is printed provides thermal stability and helps to evenly distribute heat. It can withstand high temperatures and aids in efficient heat transfer.

The thickness and composition of the resistive layer determine the resistance value and the heating capacity. A thicker layer or one with higher resistivity will produce more heat for a given current. The resistive material is often patterned to control the current path, allowing for uniform heating. The geometry of the pattern can be adjusted to achieve the desired heating profile.)

Ohmite's thick film resistors are not just components; they are highly effective heating elements, expertly engineered to convert electrical energy directly into precise thermal energy. When an electric current flows through these specialized resistors, their inherent electrical resistance efficiently dissipates energy as heat, making them ideal for a wide range of thermal applications.

The secret to their superior performance lies in the substrate upon which the thick film is printed. This robust foundation provides exceptional thermal stability and ensures even heat distribution, preventing hot spots and maximizing efficiency. Capable of withstanding high temperatures, the substrate actively aids in efficient heat transfer, ensuring your application receives consistent and reliable warmth.

We offer unparalleled control over heating performance. The thickness and composition of the resistive layer are meticulously controlled, directly determining both the resistance value and the overall heating capacity. A thicker layer or one with higher resistivity will generate more heat for a given current, allowing for fine-tuned thermal output. Furthermore, the resistive material is often precisely patterned to dictate the current path, guaranteeing uniform heating across the desired area. We can even adjust the geometry of the pattern to achieve a specific, customized heating profile to meet your exact design requirements
