GS4B034122JFT Description

The GS4B034122JFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. This ceramic-based thin-film resistor network offers a 41.2KΩ resistance per element with a tight ±5% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in precision circuits. Its ±25ppm/°C temperature coefficient enhances stability across a wide operating range (-70°C to +125°C), making it suitable for environments with thermal fluctuations. The SOIC-C series construction provides robust mechanical integrity, while the gull-wing termination ensures reliable solderability. With a 100V maximum voltage rating and 0.4W total power dissipation, this network balances compactness (4.9mm × 5.99mm × 1.45mm) with durability.

GS4B034122JFT Features

• Bussed Network Design: Simplifies PCB layout by integrating 7 resistors with a common node (BUS), reducing component count.
• High Stability: Thin-film technology and ±25ppm/°C TCR ensure minimal resistance drift under thermal stress.
• Precision Tolerances: ±5% absolute and ±1% ratio tolerance for matched performance in differential circuits.
• Robust Construction: Ceramic substrate and SOIC package offer excellent thermal and mechanical resilience.
• Wide Operating Range: Functions reliably from -70°C to +125°C, even at derated power (70°C to 125°C).
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch comply with automated assembly processes.

GS4B034122JFT Applications
