CAY16-221J4AS

CAY16-221J4AS Description

The CAY16-221J4AS from Bourns Inc. is a 4-resistor network in a compact 1206 (3216 Metric) convex package with long-side terminals, designed for surface-mount applications. This obsolete yet reliable component features isolated resistors, each with a 220Ω resistance (±5% tolerance) and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying thermal conditions. With a power rating of 63mW per element and a low-profile 0.024" (0.60mm) seated height, it suits space-constrained designs. The ROHS3-compliant device is packaged in Tape & Reel (TR) for automated assembly, adhering to MSL 1 (Unlimited) moisture sensitivity standards.

CAY16-221J4AS Features

• 4 isolated resistors in a single 1206 package, optimizing PCB space.
• 220Ω resistance with ±5% tolerance for consistent signal conditioning.
• ±200ppm/°C temperature coefficient for reliable operation in thermal-variable environments.
• 63mW power dissipation per resistor, balancing performance and thermal management.
• Compact 3.20mm x 1.60mm footprint with a 0.60mm profile, ideal for high-density layouts.
• ROHS3 compliance and EAR99/ECCN classification, ensuring environmental and export compatibility.
• Convex, long-side terminal design enhances solder joint reliability.

CAY16-221J4AS Applications

This resistor network excels in:

• Voltage division and pull-up/down circuits in embedded systems.
• Signal termination and impedance matching for communication interfaces (e.g., SPI, I2C).
• Consumer electronics, such as smart devices and wearables, where space efficiency is critical.
• Industrial control systems requiring stable resistance under thermal stress.
• Automotive electronics (non-safety-critical) due to its robust construction and tolerance.

Conclusion of CAY16-221J4AS

The CAY16-221J4AS offers a cost-effective, space-saving solution for multi-resistor applications, combining precision, thermal stability, and compactness. While obsolete, its 1206 convex package and isolated circuit design make it a viable choice for legacy designs or inventory-based projects. Engineers valuing reliability in tight layouts will find this Bourns network resistor a pragmatic option for signal conditioning and distribution tasks.
