GS4B032742CT Description

The GS4B032742CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin Narrow SOIC (SOIC-C Series) device features 7 bussed resistors with a 27.4KΩ resistance value and an ultra-tight ±0.25% absolute tolerance. Built using thin-film technology, it delivers exceptional stability with a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits, while its 100V maximum voltage rating enhances versatility. Encased in a rectangular ceramic SOIC package, it offers robust mechanical and thermal properties, ideal for surface-mount (SMD) applications.

GS4B032742CT Features

• Precision Performance: ±0.25% tolerance and ±25ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case provides superior thermal conductivity and durability compared to plastic alternatives.
• Space-Efficient Design: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch for high-density PCB layouts.
• Bussed Network: Simplifies circuit design by interconnecting resistors, reducing component count.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Gull Wing Termination: Ensures secure surface-mount soldering and compatibility with automated assembly processes.

GS4B032742CT Applications

This resistor network excels in precision analog and digital systems, including:

• Voltage Dividers & Signal Conditioning: Ideal for sensor interfaces and ADC/DAC circuits due to low tolerance and TCR.
