This document provides specifications for noise suppressor resistors intended for use in automotive ignition systems. It lists 6 resistor models between 1K0-10K ohms with tolerances of 20%, 10%, or 5% and lengths ranging from 11-18mm. The resistors are wire wound and able to withstand high voltage pulses, temperature ranges from -40-220C, and short term overloads while maintaining resistance changes below 2%. They are designed to reduce radio frequency interference caused by electrical discharges in petrol engines.
