GS4B023242FT

GS4B023242FT Description

The GS4B023242FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC package features 7 bussed resistors with a 32.4KΩ resistance value and a tight ±1% tolerance, ensuring consistent performance in precision circuits. Built with thin-film technology, it delivers excellent stability with a low ±50ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction offers robust ceramic case durability, supporting a maximum operating temperature of 125°C and a derated power range of 70–125°C. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling and compactness (4.9mm × 5.99mm × 1.45mm).

GS4B023242FT Features

• Bussed Network Design: Simplifies PCB layout with shared connections, ideal for bus line termination.
• High Precision: ±1% absolute tolerance and ±50ppm/°C TCR ensure reliable signal integrity.
• Robust Construction: Ceramic substrate and gull-wing termination enhance thermal and mechanical resilience.
• Space-Efficient: Compact SOIC package (8-pin) with 1.27mm pitch, suited for high-density boards.
• Wide Temp Range: Operates from -55°C to +125°C (derated above 70°C), outperforming standard epoxy-based networks.
• Non-Automotive: Not PPAP-capable, but excels in industrial, telecom, and instrumentation applications.
