NSR

NSR Vishay Dale Wirewound Resistors, Noise Suppressor 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 RoHS COMPLIANT 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.
