GS4B032871GT

GS4B032871GT Description

The GS4B032871GT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 2.87KΩ resistance per element and a tight ±2% absolute tolerance, this ceramic-based network ensures reliable signal conditioning and voltage division. Its thin-film technology and ±25ppm/°C temperature coefficient deliver exceptional stability across a wide operating range (70°C to 125°C), making it suitable for environments with thermal fluctuations. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly in space-constrained designs. Rated for 100V maximum voltage and 0.4W total power dissipation, it balances compactness (4.9mm × 5.99mm × 1.45mm) with robust performance.

GS4B032871GT Features

• Bussed Network Architecture: Simplifies PCB layout by connecting resistors in a common bus configuration.
• High Precision: ±2% tolerance and ±25ppm/°C TCR ensure minimal drift in critical circuits.
• Ceramic Substrate: Enhances thermal management and durability vs. polymer-based alternatives.
• Thin-Film Technology: Offers lower noise and better long-term stability compared to thick-film networks.
• Compact SOIC Package: 1.27mm terminal pitch and 1.63mm seated height enable high-density mounting.
• Derated Power Handling: Supports 0.05W per resistor (0.4W total) at elevated temperatures up to 125°C.

GS4B032871GT Applications

Ideal for precision analog circuits, sensor interfaces, and voltage dividers in:

• Industrial Control Systems: Stable resistance for PLCs and instrumentation.
• Medical Devices: Reliable performance in patient monitoring equipment.
• Automotive Electronics (non-AECQ): Non-safety-critical modules like infotainment.
• Test & Measurement Equipment: Low-noise signal conditioning for accuracy.
• Power Management: Feedback networks in DC-DC converters.

Conclusion of GS4B032871GT

The GS4B032871GT excels in applications demanding tight tolerance, thermal stability, and compact form factors. Its ceramic construction and thin-film technology provide a competitive edge in harsh environments, while the bussed design reduces component count. Though not PPAP-capable or automotive-grade, it remains a cost-effective solution for industrial and medical electronics where precision and reliability are paramount. Engineers should verify EU RoHS non-compliance for regulatory alignment.
