GS8A021872CAT Description

The GS8A021872CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 16-pin narrow SOIC device features 8 isolated thin-film resistors, each with a resistance value of 18.7KΩ and an absolute tolerance of ±0.25%, ensuring exceptional accuracy. The network operates within a wide temperature range of 70°C to 125°C and offers a low temperature coefficient of ±50ppm/°C, making it ideal for stable performance in varying thermal conditions. Encased in a rectangular ceramic SOIC package, it provides robust mechanical durability and reliable surface-mount (SMD) compatibility. With a power rating of 0.1W per resistor (0.8W total) and a maximum voltage rating of 100V, this component is engineered for precision analog and digital circuits.

GS8A021872CAT Features

• High Precision: ±0.25% absolute tolerance and ±0.05% ratio tolerance for critical signal conditioning.
• Stable Performance: ±50ppm/°C TCR ensures minimal resistance drift across temperature fluctuations.
• Robust Construction: Ceramic case (SOIC) enhances thermal and mechanical reliability.
• Isolated Resistors: 8 independent thin-film resistors prevent crosstalk in multi-channel designs.
• Surface-Mount Ready: Gull-wing termination (1.27mm pitch) for easy PCB integration.
• Wide Operating Range: 125°C maximum temperature and derated power up to 70°C.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications.
