745C101331JTR

745C101331JTR Description

The 745C101331JTR from CTS Resistor Products is an 8-resistor bussed network array designed for high-density PCB applications. Housed in a compact 2512 (6432 Metric) concave long-side terminal package, it features a 330Ω resistance per element with a ±5% tolerance and ±250ppm/°C temperature coefficient. With a 0.028" (0.70mm) seated height and 6.40mm x 3.20mm dimensions, this surface-mount device (SMD) is optimized for space-constrained designs. The 63mW power rating per element ensures reliable performance in low-power circuits, while its ROHS3 compliance and REACH-unaffected status make it environmentally friendly. Although marked as obsolete, it remains a robust choice for legacy or specialized applications.

745C101331JTR Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a single common node, reducing component count.
• Concave Long-Side Terminals: Enhances solder joint reliability and mechanical stability in high-vibration environments.
• Low Profile (0.70mm): Ideal for slimline consumer electronics and portable devices.
• Wide Operating Range: Stable performance across industrial temperatures (±250ppm/°C).
• Tape & Reel (TR) Packaging: Supports automated assembly processes for high-volume production.
• MSL1 (Unlimited): No baking required prior to reflow, minimizing handling complexity.

745C101331JTR Applications

This resistor array excels in DDR SDRAM, DRAM, and MDDR memory modules, where precise termination and signal integrity are critical. Its bussed design is particularly advantageous in:

• Voltage Divider Networks: For ADC/DAC reference circuits.
• Pull-Up/Pull-Down Configurations: In microcontroller and FPGA I/O interfaces.
• Legacy Systems: Where obsolete component replacements are needed without redesign.
• Consumer Electronics: Such as laptops and tablets, requiring compact, high-reliability passives.

Conclusion of 745C101331JTR

The 745C101331JTR offers a balance of miniaturization, reliability, and ease of integration, making it a pragmatic choice for memory-related and low-power analog circuits. While obsolete, its concave terminal design and bussed architecture provide distinct advantages over standard arrays in specific use cases. Engineers should evaluate alternative modern equivalents for new designs but can leverage this model for repairs or backward-compatible systems. CTS Corporation’s legacy of precision resistors ensures consistent performance, even in demanding environments.
