TT Electronics has expanded its family of surface-mount resistors with the introduction of its Metal Foil Chip (MFC) resistors. The MFC series uses metal foil on ceramic technology to provide enhanced reliability for automotive, industrial, and medical applications. These current-sense resistors are suited for products that require control and monitoring of energy consumption, such as battery-operated portable and IoT devices, said the company.
The metal foil on ceramic technology combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element. This results in better surge tolerance than thick-film options and lower self-heating levels than thick-film or metal strip resistors, said TT Electronics.
Key features include:
- Small size down to 0402
- Tolerance to ±0.5%
- TCR to ±50 ppm/°C
- High power density
- AEC-Q200 qualified (excluding 0.5% tolerance)

Available in six sizes from 0402 to 2512, the MFC series of surface-mount resistors offer a broad resistance range from 2 to 200 milliohm, and precision to ±0.5% and ± 50 ppm/°C. The resistors are AEC-Q200 qualified, and can be used for automotive DC-DC conversion, DC motor control, actuator control, power supply monitoring, portable device battery management systems, and LED drivers.
