Vishay has introduced a new series of wirewound noise suppressor resistors that delivers improved voltage performance and reliability for automotive ignition systems in reciprocating engines.
Vishay Dale NSR-HP series devices feature a coating that increases reliability by protecting the resistive element against moisture and mechanical shock, while enabling high voltage performance to 45 kV and high operating temperatures to +200°C. The resistors can withstand high-voltage pulses at high frequencies and feature a dielectric withstand voltage of 1000 V a.c.
Ideal for reducing RFI during electrical discharges in gasoline engines, the NSR-HP series can be used in spark plug leads, as well as in spark plug caps. The devices are available with wide ohmic and inductance value ranges from 1 kΩ to 15 kΩ and 9 μH to 78 μH, respectively, and feature a temperature coefficient of ±250 ppm/°C.
