For Automotive Ignition Systems, Devices Offer Voltages to 45 kV and High Operating Temperatures to +200 °C

MALVERN, Pa. — Jan. 24, 2018 — Vishay Intertechnology, Inc. (NYSE: VSH) today 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 VAC.

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.

The resistors are RoHS-compliant, halogen-free, and Vishay Green.

Samples of the NSR-HP series are available now. Production quantities will be available in March, with lead times of 16 weeks.
