GS4B032550GDT Description

The GS4B032550GDT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. With a 255Ω resistance value and ±2% absolute tolerance, this thin-film resistor network ensures reliable performance in precision circuits. Its ±25ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for stable operation across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The 100V maximum voltage rating and gull-wing termination enhance durability in high-density PCB layouts.

GS4B032550GDT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances, ensuring mechanical stability.
• Bussed Network Design: Simplifies circuit layout with 7 resistors connected to a common bus (BUS designator), reducing component count.
• High Precision: ±2% tolerance and ±0.5% ratio tolerance for matched resistance values, critical for differential amplifiers or voltage dividers.
• Thin-Film Technology: Delivers low noise and stable performance over temperature, outperforming thick-film alternatives.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its 125°C rating suits industrial and telecom applications.
