GS4B023742BAT Description

The GS4B023742BAT 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 applications, it features a 37.4KΩ resistance value with an absolute tolerance of ±0.1% and a ratio tolerance of ±0.05%, ensuring exceptional accuracy. The thin-film technology and ±50ppm/°C temperature coefficient provide stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4B023742BAT Features

• Ceramic Case & SOIC Package: Robust rectangular ceramic construction (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• High Precision: 0.1% tolerance and ±50ppm/°C TCR for minimal drift in critical applications.
• Bussed Network: Simplified circuit design with 7 resistors connected to a common bus (BUS designator).
• Thin-Film Technology: Delivers low noise and stable performance.
• Wide Operating Range: Rated for 125°C maximum temperature and derated power up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its precision suits industrial and instrumentation uses.
