Vishay’s New Automotive Precision Thin Film Chip Resistor Array is Tested According to AEC-Q200 and Offers 1000-V ESD Stability
Device Offers Film Temperature up to +155 °C and Tolerance Matching Down to 0.1 %
Vishay Intertechnology, Inc. (NYSE: VSH) announced the release of the ACAS 0612 AT automotive precision thin film chip resistor array, which is tested according to AEC-Q200 and offers a 1000-V ESD stability rating. The device is optimized to meet new automotive industry requirements for temperature and humidity, while offering high repeatability and stable performance for industrial, telecommunication, and consumer electronics.
The new Vishay Beyschlag ACAS 0612 AT resistor array offers defined tolerance matching down to 0.1 % (equivalent to ±0.05 %) and TCR tracking down to 10 ppm/K (equivalent to ±5 ppm/K), making it ideally suited for precision analog circuit, voltage divider, feedback circuit, and signal conditioning applications that require extraordinarily stable fixed resistor ratios.
The device delivers stable performance for automotive electronics, including engine control units, gear box controls, information, safety, power supply, body electronics, and braking systems; industrial electronics, such as energy management, measurement control, steering technology, sensors, scales, and bridged and precision amplifiers; telecommunication electronics such as display technology and base stations; and consumer electronics including high-end audio and studio technology.
With an absolute TCR down to ±25 ppm/K, the ACAS 0612 AT features a maximum film temperature of +155 °C and a 75-V operating voltage. The device is offered with resistance values from 47 Ω to 150 kΩ in two pairs or four equal resistor values. Each resistance element is rated to 0.1-W dissipation, up to a maximum of 0.3 W per package.
The resistor array offers a low cost when compared to using four high-precision resistors, and its small 1.5-mm by 3.2-mm package enables the design of high-density circuits. Suitable for processing on automatic SMD assembly systems, the new device is RoHS-compliant and compatible with lead (Pb)-free and tin/lead (Sn/Pb) reflow and vapor-phase soldering processes.
