Surface mount resistors use metal foil for enhanced reliability

06-01-2021 | TT Electronics | Passives

TT Electronics offer its Metal Foil Chip resistors. The MFC series employs metal foil on ceramic technology, which connects the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, subsequently, delivers better surge tolerance than thick-film options and lower self-heating levels than thick-film or metal strip resistors. The devices are ideal for automotive, industrial, and medical applications.


“The development of our MFC series resistors was driven by the explosive growth of products that require control and monitoring of energy consumption, such as battery-operated portable and IoT devices,” said Barry Peters, VP Product Management and Engineering, TT Electronics. “To meet rising demands in this arena, TT has enhanced its current sense resistor portfolio with the debut of the MFC series, offering a wider range of sizes and values than many of our top competitors.”


These resistors reduce PCB area use, free up error budget to allow precision needs to be relaxed elsewhere in the design, and finally enhance product reliability. Offered in six sizes from 0402 to 2512, the series also provides a wide range of milliohm options, from 2 to 200, and precision to ±0.5% and ±50ppm/C. AEC-Q200 qualified, the series can be employed for automotive DC-DC conversion, DC motor control, power supply monitoring, actuator control, portable device battery management systems, and LED drivers.
