AEC-Q200 qualified high power resistors help cut component count
Vishay Intertechnology has introduced high power resistors with AEC-Q200 automotive qualification. Designed for direct mounting on a heatsink, the Vishay Sfernice LPSA 300, LPSA 600, and LPSA 800 deliver high power dissipation and pulse handling capabilities to help designers reduce component counts and lower costs in automotive applications.
The devices will serve as precharge or discharge resistors for inverters, and converters in electric vehicles, hybrid electric vehicles and plug-in hybrid electric vehicles. With rated power of 300W, 600W, and 800W, respectively, the LPSA 300, LPSA 600, and LPSA 800 enable designers to replace multiple lower power components with a single resistor in these applications. In addition, their pulse capability from 400J to 1500J for pulses from 0.05s to 0.5s allows them to replace larger wirewound resistors to save board space.
The LPSA 300, LPSA 600, and LPSA 800 offer high temperature operation to +175 degrees C and a broad range of resistance values from 0.03-Ohm to 900-kOhm. They are also capable of high dielectric strength up to 12kV RMS.
The RoHS-compliant devices offer a non-inductive design, tolerances down to ± 1 per cent and superior automotive reliability test results, such as extensive temperature cycling at 1,000 cycles and 1,000 hours of operational life.
Samples and production quantities of the new resistors are available now, with lead times of 10 to 12 weeks.
Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
