GS4A031961FBT Description

The GS4A031961FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 1.96KΩ and an absolute tolerance of ±1%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient (±25ppm/°C), ensuring stable performance under thermal stress. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, it is engineered for reliability in precision circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal dissipation.

GS4A031961FBT Features

• Isolated Resistors: Four independent resistors in a single SOIC package, reducing board space and simplifying design.
• High Precision: ±1% absolute tolerance and ±0.1% ratio tolerance for critical analog and signal conditioning applications.
• Robust Construction: Ceramic substrate ensures high thermal stability and mechanical strength.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Low TCR: ±25ppm/°C minimizes resistance drift across temperature variations.
• Surface-Mount Ready: Gull-wing leads and 1.27mm terminal pitch comply with standard SOIC assembly processes.
