TECHNOLOGY

The resistor element is a resistive wire, which is wound in a single layer on a fiberglass core. Metallic caps or electrodes are

fixed to the ends of the resistive core, following the specific ignition system characteristics. A coating protects the resistive

element against moisture and mechanical shock, plus is able to withstand high temperatures. These products can be molded

with epoxy resin, thermoplastic or thermo set materials.
