Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced that it has extended the ohmic value of its MCW 0406 AT Precision series wide-terminal film chip resistors to 1?, which is the lowest resistance in the industry. of. The resistors have low ohmic values ​​and ±0.1% precision tolerances, as well as ±25ppm/K precision TCR.

At 70 ° C ambient temperature, Vishay 's MCW 0406 AT precision resistors have high temperature performance of +155 ° C and power dissipation of up to 250 mW. These performance metrics allow designers to use these resistors in harsh and high temperature environments without making concessions at power levels or electrical performance. These devices are equally competent, regardless of whether the application requires the resistor to operate at full power or only some of the rated power for better stability.

Vishay Beyschlag MCW 0406 AT not only has excellent high temperature performance, but also is extremely stable in the face of thermal cycling and excessive humidity. On 4-layer FR4 printed circuit boards, these devices can handle 2,500 rapid temperature changes from -40°C to +125°C. Vishay uses a special paint system to achieve very good moisture resistance. The device has also been certified for accelerated aging tests including operation at +85 ° C and 85% relative humidity for 1000 hours, making the MCW 0406 AT suitable for almost all applications.

MCW 0406 AT precision resistors are AEC-Q200 certified and are an excellent choice for new professional power management electronics in many areas. The main considerations for these electronics are reliability, stability, power dissipation and robust design. Typical applications include power management in industrial and automotive electronics such as xenon and LED lighting systems, engine control units, transmission control and brake systems.

Samples of the enhanced resistors are available now, with volume production scheduled for February 2013, with lead times of eight to ten weeks for larger orders.
