Introduction to Film Resistors Film resistors are built either on cylindrical rods or on planar substrates. Usually, the material in the rods and substrates is ceramic in the state of aluminum oxide (alumina), but glass may occur. Hollow cores exist but are more and more abandoned when sizes are becoming smaller. This design suffers also from drawbacks: the construction is more fragile and the heat dissipation is poorer than that of a solid core.

Stackpole extended their RNCF0402 size NiCr precision chip resistor, increasing the power rating to 0.1W for resistance values from 4.7 ohms to 255K for 0.1% tolerances and 25 ppm TCR. As electronics continue to downsize and add functionality, there is a consistent need for smaller and more precise chip resistors. If the application requires both small size and high power handling, then finding suitable precision resistors may be challenging.
