GS4A029101FAT

GS4A029101FAT Description

The GS4A029101FAT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Built with ceramic substrate and thin-film technology, it delivers stable performance with a ±50ppm/°C temperature coefficient and ±1% absolute tolerance. Each resistor offers 9.1KΩ resistance at 0.1W (1/10W) power rating per element, with a total power dissipation of 0.4W. The SOIC-C series features gull-wing terminations for reliable surface-mount assembly, and its 100V maximum voltage rating ensures robustness in demanding circuits.

GS4A029101FAT Features

• Precision Network: 1% tolerance with ±0.05% ratio tolerance for matched resistance values.
• High-Temperature Operation: Rated for 125°C max operating temperature, derated up to 70–125°C.
• Stable Thin-Film Technology: Low TCR (±50ppm/°C) ensures minimal drift.
• Compact & Robust: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) ceramic case with ±0.1mm dimensional tolerances.
• Isolated Design: Independent resistors (non-bussed) for flexible circuit integration.
• Industrial-Grade: Non-automotive (PPAP: No) but suitable for high-reliability applications.
