GS4B027321DT Description

The GS4B027321DT 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. Featuring a 7.32KΩ resistance per element with an ultra-tight ±0.5% tolerance, this thin-film ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction offers 0.4W total power dissipation (0.05W per resistor) and robust gull-wing termination for reliable PCB mounting.

GS4B027321DT Features

• High Precision: ±0.5% absolute tolerance ensures minimal deviation in critical circuits.
• Stable Thermal Performance: ±50ppm/°C TCR and derated operation up to 125°C.
• Robust Construction: Ceramic substrate with rectangular SOIC package (4.9mm × 5.99mm × 1.45mm).
• Bussed Design: Simplified routing for bus termination, pull-up/down networks, and voltage dividers.
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads for automated assembly.
