ACASA200212002P500 Description

The ACASA200212002P500 from Vishay is a high-precision thin-film resistor array designed for demanding surface-mount applications. This 4-resistor ISOL (isolated) network features a 20KΩ/20KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a conformal-coated 1206 (4 x 0603) package, it offers 0.3W total power dissipation (0.1W per resistor) and a 75V maximum voltage rating, making it suitable for precision analog and digital circuits. The convex termination style enhances solder joint reliability, while the tape-and-reel packaging facilitates automated assembly.
