Malvern, Pa. Vishay Intertechnology, Inc. has released 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, Vishay said.
The Vishay Beyschlag ACAS 0612 AT resistor array offers tolerance matching down to 0.1% (equivalent to ±0.05%) and temperature coefficient of resistance (TCR) tracking down to 10 ppm/K (equivalent to ±5 ppm/K), making it well-suited for precision analog circuit, voltage divider, feedback circuit, and signal conditioning applications that require highly stable fixed resistor ratios.
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 ohms (Ω) to 150 kΩ in two pairs or four equal resistor values.
The resistor array is said to offer a low cost when compared to using four high-precision resistors, and its small 1.5 x 3.2-mm package enables the design of high-density circuits.
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.
Suitable for processing on automatic SMD assembly systems, the ACAS 0612 AT is RoHS-compliant and compatible with lead (Pb)-free and tin/lead (Sn/Pb) reflow and vapor-phase soldering processes. The device also complies with the GADSL and the CEFIC-EECA-EICTA list of legal restrictions on hazardous substances. This includes full compliance with 2000/53/EC End of Vehicle life (ELV), 2000/53/EC Annex II to End of Vehicle Life (ELV II) directives, 2002/95/EC Restriction of the use of Hazardous Substances (RoHS), and 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE).
