RACF648RJT150K Description

The RACF648RJT150K from Stackpole Electronics, Inc. is a thick-film resistor array designed for high-density surface-mount applications. This 8-resistor network features a 150K Ohm resistance per element with a 5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C operating range. Encased in a molded 2512 (8 x 1206) package, it offers a compact footprint with 10 concave-terminated pins for reliable solderability. The array delivers a total power rating of 0.5W (1/2W) and 0.063W (1/16W) per resistor, with a 50V maximum voltage rating, making it suitable for low-to-moderate power circuits.
