GS4A011243BBT Description

The GS4A011243BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 124KΩ and an absolute tolerance of ±0.1%, ensuring exceptional accuracy. The network operates over a wide temperature range (70°C to 125°C) with a ±100ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Encased in a rectangular ceramic SOIC package, it offers 0.1W power dissipation per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A011243BBT Features

• High Precision: ±0.1% absolute and ratio tolerance for critical signal conditioning.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Isolated Resistors: Four independent 124KΩ resistors reduce crosstalk in sensitive circuits.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive (non-PPAP) applications.
• Low TCR: ±100ppm/°C minimizes resistance drift under temperature variations.
• Compact Footprint: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight dimensional tolerances (±0.1mm).
