Vishay introduces 0406 thin film resistors with wide connectors in small form factor

     Vishay Intertechnology, Inc. announced the introduction of its new professional and precision series of wide-joint thin-film resistors, the MCW 0406 AT, which are the first such devices to feature the 0406 small form factor. The MCW 0406 AT professional and precision resistors provide consistent performance in harsh and high-temperature applications. The Professional series devices can operate for 10 hours at high temperatures of 175 ° C, and the power level can reach 300mW at ambient temperatures of 85 ° C. Compared with conventional resistors, the MCW 0406 AT series can reach a film temperature of 125 ° C or 155 ° C at a rated condition of 70 ° C, setting a new industry standard in technology and performance.

     There is an increasing demand for electronic components that can handle higher temperatures and higher power. However, as long as the component is installed in a place where there is heat, the electrical heat dissipation of the resistor will be greatly reduced due to the limitation of the allowed film temperature, and the high temperature will also increase the drift of the resistance value.

     The high temperature and thermal rating of the MCW 0406 AT resistor allows designers to use these devices in harsh and high-temperature environments without sacrificing power levels or electrical performance. Whether it is to use the full power, or to obtain better stability, using only a part of the nominal heating power rating, the use of these devices is the same.

     The MCW 0406 AT series has excellent high temperature performance, including a strong ability to cope with thermal cycling and high humidity. Thanks to the use of a special paint to achieve high moisture resistance, the device can withstand 2,500 rapid temperature changes from -40 ° C to 125 ° C on a 4-layer FR4 printed circuit board. The device is also subjected to similar accelerated aging tests, including 1,000 hours at 85 ° C and 85 percent relative humidity, making it suitable for almost all applications. For automotive applications, these resistors will soon be AEC-Q200 certified.
