TT Electronics' New Surface Mount Resistors Leverage Metal Foil on Ceramic Technology for Enhanced Reliability 

Ideal for automotive, industrial, and medical applications, TT's MFC series offers compact current sensing and heat spreading capabilities to outperform alternative options


Woking, UK, November 17, 2020

TT Electronics, a global provider of engineered electronics for performance critical applications, today announced the introduction of its Metal Foil Chip (MFC) resistors. The MFC series uses metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This, in turn, offers better surge tolerance than thick-film options and lower self-heating levels than thick-film or metal strip resistors, well-suited 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.”

MFC resistors minimise the use of PCB area, free up error budget to enable precision requirements to be relaxed elsewhere in the design, and ultimately enhance product reliability. Available in six sizes from 0402 to 2512, the MFC series also offers a broad range of milliohm options, from 2 to 200, and precision to ±0.5% and ±50ppm/°C.  AEC-Q200 qualified, the MFC series can be utilized for automotive DC-DC conversion, DC motor control, actuator control, power supply monitoring, portable device battery management systems, and LED drivers.
