FEATURES
Ideal for reducing RFI during electrical
discharges on gasoline engines
Variety of resistance and inductance values
available
Special design of electrical contacts upon
request
Capability to withstand high voltage pulses at high
frequency
Compliant to RoHS directive 2002/95/EC
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.
