Vishay Intertechnology have today announced the extension of its MC series of professional and precision thin film chip resistors. Now with lower ohmic values in the compact 0402 and 0603 case sizes, the enhanced MC series devices are designed to deliver stable performance for a wide range of electronic systems, particularly for applications in which reliability and stability are a major concern.

For all TCR / tolerance combinations, the professional and precision series now offer resistance down to 10 Ω and 100 Ω, respectively, in the 0402 case size. In the 0603 case size, the professional series features lower resistance down to 1 Ω for TCRs of ± 50 ppm/K and ± 25 ppm/K with a 0.5 % tolerance.

The new thin film chip resistors are ideal for applications including industrial electronics such as sensors, scales, bridges, and precision amplifiers; automotive electronics such as engine control units, gearbox controls, body electronics, and safety, power supply, and braking systems; battery management, measurement control, and steering technology; telecommunication base stations; and medical equipment.

Offering an advanced level of stability, precision series devices offer low tolerance down to ± 0.1 % and low TCR down to ± 10 ppm/K. Providing high-temperature performance, professional series devices combine high rated dissipation at 70 °C to 400 mW with an operating temperature to +155 °C. MC series resistors are approved according to EN 140401-801. RoHS-compliant, the devices are suitable for processing on automatic SMD assembly systems and for automatic soldering using wave, reflow, or vapor phase.
