MPMA AEC-Q200 Surface-Mount Resistor Networks Vishay / Thin Film MPMA AEC-Q200 Surface-Mount Resistor Networks are AEC-Q200 qualified and feature ±2ppm tracking and a ratio tolerance as tight as ±0.05%. The series offers exceptional long-term ratio stability for surface-mount applications. The standard SOT-23 package format, with unity and common standard resistance divider ratios, provides easy selection for most applications requiring matched pair resistor elements. Vishay / Thin Film MPMA AEC-Q200 Surface-Mount Resistor Networks are ideal for high-precision automotive applications such as keyless entry, networked doors, and mirrors, power steering, audio systems, GPS/navigation systems, pressure monitoring, optical sensors, microcontrollers, isolation, and power.
