GS4B031541GT Description

The GS4B031541GT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 1.54KΩ resistance per element with a tight ±2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. The thin-film technology ensures low noise and high reliability, while the ceramic case provides excellent thermal stability. Rated for 0.05W (1/20W) per resistor and 0.4W total power, it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The 100V maximum voltage rating and gull-wing termination facilitate robust surface-mount assembly.

GS4B031541GT Features

• Bussed Network Design: 7 resistors connected in a bus configuration, simplifying PCB layout.
• High Precision: ±2% absolute tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm dimensional tolerances.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive (non-PPAP) applications.
• Thin-Film Technology: Delivers low noise, high accuracy, and long-term reliability.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for easy assembly.

GS4B031541GT Applications

This resistor network excels in precision analog circuits, voltage dividers, and signal conditioning where stability and compactness are critical. Its bussed architecture reduces component count in bus termination, pull-up/pull-down networks, and ADC/DAC interfaces. The ceramic package makes it suitable for high-temperature environments, such as power supplies, industrial controls, and instrumentation. While not PPAP-certified, it’s a cost-effective choice for prototyping and non-automotive commercial electronics.

Conclusion of GS4B031541GT

The GS4B031541GT combines precision, durability, and space efficiency, offering a reliable solution for high-density PCB designs. Its thin-film ceramic construction, tight tolerances, and bussed topology provide distinct advantages over generic resistor arrays. Ideal for industrial, telecom, and test equipment, this network balances performance with manufacturability, though designers should note its non-RoHS compliance for restricted applications.
