ACASA1001S1002P100 Description

The ACASA1001S1002P100 from Vishay is a high-precision thin-film resistor array designed for demanding surface-mount applications. This 4-resistor network features isolated (ISOL) circuit design with resistance values of 1KΩ and 10KΩ, offering ±0.1% tolerance and an ultra-low ±25ppm/°C temperature coefficient. Encased in a conformal-coated 1206 (4×0603) package, it delivers 0.3W total power dissipation (0.1W per resistor) and operates reliably across a wide temperature range of -55°C to +125°C, with derated performance up to 125°C. Its 8-pin convex termination ensures robust solderability, while the 75V maximum voltage rating enhances durability in high-voltage circuits. Compliant with EU RoHS (with exemption) and packaged in tape and reel (T/R), it is optimized for automated assembly.
