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.
