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
TECHNOLOGY
The resistor element is a resistive wire, which is wound in a single layer on a fiberglass core (ceramic core for type 3 shown
below). 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, mechanical shock and is able to withstand high
temperatures. These products can be moulded with epoxy resin, thermoplastic or thermo set plastic materials.
Notes:
(1) Special resistance values available upon request
(2) Other tolerances available upon request
(3) Special inductance values available upon request
