RACF164DJT680K

RACF164DJT680K Description

The RACF164DJT680K is a 4-resistor network from Stackpole Electronics Inc's RACF series, designed for high-density surface-mount applications. This 1206 (3216 Metric) concave long-side terminal package offers a compact footprint of 0.126" x 0.063" (3.20mm x 1.60mm) with a low profile of 0.030" (0.75mm), making it suitable for space-constrained PCB designs. Each resistor in the array provides a 680kΩ resistance with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. The isolated circuit configuration allows independent resistor operation, enhancing design flexibility.
