CAY10-472J4

CAY10-472J4 Description

The CAY10-472J4 from Bourns Inc. is a compact 4-resistor network designed for high-density surface-mount applications. This obsolete yet reliable component features isolated resistors, each with a 4.7kΩ resistance and a ±5% tolerance, ensuring stable performance in precision circuits. Encased in an 0804 convex package with long-side terminals, it measures just 2.00mm x 1.00mm (0.079" x 0.039") with a low-profile 0.45mm (0.018") height, making it ideal for space-constrained designs. The device operates within a ±250ppm/°C temperature coefficient and delivers 62.5mW power per element, suitable for low-power applications. Packaged in Tape & Reel (TR) for automated assembly, it complies with REACH and EAR99 regulations.

CAY10-472J4 Features

• 4 isolated resistors in a single 8-pin package, reducing board space and assembly complexity.
• Compact 0804 footprint with convex, long-side terminals for robust mechanical stability.
• Wide tolerance (±5%) and ±250ppm/°C TCR for moderate precision requirements.
• 62.5mW power rating per resistor, balancing performance and thermal management.
• MSL 1 (Unlimited) moisture sensitivity, ensuring compatibility with standard handling processes.
• Surface-mount design for streamlined PCB integration in automated production lines.

CAY10-472J4 Applications

This resistor network excels in analog signal conditioning, voltage division, and pull-up/pull-down circuits in consumer electronics, IoT devices, and industrial controls. Its isolated configuration is ideal for multi-channel sensor interfaces or ADC/DAC reference networks, where consistent resistance values are critical. The low-profile design suits wearables and ultra-thin PCBs, while its Tape & Reel packaging aligns with high-volume manufacturing.

Conclusion of CAY10-472J4

While marked obsolete, the CAY10-472J4 remains a viable choice for legacy designs or replacements due to its space efficiency, stable performance, and ease of integration. Its combination of moderate precision, compact form factor, and isolated circuit topology makes it a pragmatic solution for cost-sensitive, space-optimized applications. Engineers should verify alternative availability or consider Bourns' newer series for forward-looking projects.
