Vishay introduces a new type of hybrid wound wire charging resistor certified by AEC-Q200

     Vishay Intertechnology, Inc announced the launch of a new charging resistor, HRHA, which is AEC-Q200 certified, advanced in the industry and adopts hybrid winding technology and standard package size.

     Vishay MCB HRHA has a maximum operating temperature of+250 C and can be used as the pre charge discharge resistance of inverters and converters for electric vehicles (EVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs). In general, designers must use multiple thick film resistors to meet the high pulse requirements of these applications. Under the same size, the energy absorption capacity of HRHA is ten times higher (i.e. 6 kJ, 300 ms), so a single resistor can replace multiple thick film resistors, reducing the cost of the overall solution.

     The device released recently has a rated power of 90 W on stainless steel and 54 W on Pamitherm. High resistance accuracy and stability, with a tolerance of 5%, TCR temperature coefficient as low as 100 ppm/C, and resistance value range of 1 to 1 k. HRHA is easy to install and uses 6.35 mm quick connect terminals. The device can be fixed on the heat sink, and the integrated fuse is optional.
