CLTE laminates have proven excellent dimensional stability and low planar CTE, providing consistent performance for embedded resistors: among the lowest variance available for PTFE-based laminates. CLTE laminates have a long history of use with Resistor Foil and are available with a full range of other cladding types (including electrodeposited, reverse treated copper, rolled copper foil or more). CLTE laminates’ tried and tested performance continues to make them a top choice for a wide range of ground-based and airborne communications and radar systems.


  • Low thermal expansion in X, Y and Z of 10, 12 and 34 ppm/°C
