CAY16-472J2LF

CAY16-472J2LF Description

The CAY16-472J2LF by Bourns Inc. is a compact, surface-mount resistor network designed for high-density PCB applications. This obsolete but reliable component features two isolated 4.7kΩ resistors with a ±5% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in a 0606, convex package (1.60mm x 1.60mm), it offers a low-profile height of 0.60mm, making it suitable for space-constrained designs. With a 62.5mW power rating per element, it balances power handling and miniaturization. The device is RoHS3 compliant and REACH unaffected, adhering to stringent environmental standards.
