Noise suppressor resistors meet automotive ignition systems
Vishay Intertechnology has introduced a 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 have a coating that increases reliability by protecting the resistive element against moisture and mechanical shock while enabling high voltage performance to 45kV and high operating temperatures to +200 degree C. The resistors can withstand high voltage pulses at high frequencies, says Vishay, and have a dielectric withstand voltage of 1000V AC.
The NSR-HP series resistors are suitable for reducing RFI during electrical discharges in gasoline engines. They can be used in spark plug leads, as well as in spark plug caps.
The resistors are available with wide Ohmic and inductance value ranges from one to 15kOhm and nine to 78-micro H, respectively, and feature a temperature co-efficient of ± 250ppm/degree C.
The resistors are RoHS-compliant, halogen-free, and confirm to the Vishay Green policy.
Samples of the NSR-HP series are available now. Production quantities will be available in March, with lead times of 16 weeks.
Vishay Intertechnology is one of the world’s largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in a selection of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
