New MCW 0612 AT Professional Series of Wide Terminal Thin Film Chip Resistors Features 1 W Power Rating in Compact 0612 Case Size
The News
Vishay Intertechnology announces that the company has extended its MCW AT Professional family of wide terminal thin film chip resistors by supplementing the existing MCW 0406 AT line with an additional case size for power handling of up to 1 W. For power electronics in industrial and automotive applications, Vishay Beyschlag MCW 0612 AT Professional devices provide high power dissipation, high-temperature performance, and renowned thin film long-term stability.
- Offer up to four times higher power dissipation when compared to standard resistors in the 1206 footprint
- Significantly lower costs by replacing multiple resistors of the same size or larger devices with equivalent power ratings
- Wide terminal contact geometry allows for superior robustness against thermal cycling
- Automotive applications will benefit from AEC-Q200 qualification and high operating temperatures
Product Benefits:
- Wide terminal thin film chip resistor in compact 0612 case size
- High power dissipation to 1 W
- Replaces large chip sizes, including 2512
- High operating temperatures to +175 °C
- TCR down to ± 25 ppm/K and tolerance to ± 0.5 %
- Resistance range from 10 Ω to 100 kΩ
- AEC-Q200 qualification under preparation
- Advanced sulfur resistance
The Perspective:
The specifications of the MCW 0612 AT Professional series resistors allow designers to use them in harsh and high-temperature environments without compromising power rating or electrical performance, while complying with today’s requirements for miniaturization. The devices are equally effective whether the application requires their full power capability or only a fraction of the nominal rated dissipation in order to gain improved stability. The MCW 0612 AT Professional series is the perfect choice for most fields of modern professional power electronics in which power dissipation, reliability, stability, and robust design are major concerns.
