GS4B031301JFT Description

The GS4B031301JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 1.3KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched-resistor applications. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling for low-power analog and digital circuits.

GS4B031301JFT Features

• Ceramic Case & Thin Film Technology: Ensures high stability, low noise, and excellent thermal performance.
• Bussed Network (BUS): Simplifies circuit design by interconnecting resistors, reducing component count.
• Precision Tolerance: ±5% absolute and ±1% ratio tolerance for matched resistance values.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive (non-PPAP) applications.
• Compact SOIC Package: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with gull-wing terminals for easy surface mounting.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.
