GS4B0126R7GGT

GS4B0126R7GGT Description

The GS4B0126R7GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a ceramic SOIC package, this thin-film resistor network offers a 26.7Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance across all resistors. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The 8-pin narrow SOIC (SOIC-C) package features gull-wing terminations for reliable surface-mount assembly, with a compact footprint of 4.9mm (L) × 5.99mm (D) × 1.45mm (H). Rated for 100V maximum voltage and 0.4W total power dissipation, it balances durability with space efficiency.

GS4B0126R7GGT Features

• Bussed Network Design: Simplifies PCB layout by connecting resistors in a common bus configuration, reducing component count.
• Ceramic Substrate: Enhances thermal stability and mechanical robustness compared to polymer-based networks.
• Precision Thin-Film Technology: Delivers low noise and high accuracy (±2% tolerance) for signal conditioning and voltage division.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive (non-AEC-Q200) applications.
• Compact SOIC Package: Saves board space while supporting automated SMT processes (1.27mm terminal pitch).
• Non-RoHS Compliant: Suitable for legacy or specialized systems where lead-free alternatives are unsuitable.

GS4B0126R7GGT Applications

This resistor network excels in:

• Voltage Division Circuits: Precision dividers in sensor interfaces or ADC reference networks.
