GS4A034121GBT

GS4A034121GBT Description

The GS4A034121GBT from TT Electronics/IRC is a high-precision 4-resistor network designed for demanding isolation and signal conditioning applications. Housed in an 8-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a 4.12KΩ resistance value, ±2% absolute tolerance, and an ultra-stable ±25ppm/°C temperature coefficient. The device operates across a 70°C to 125°C derated power range, with a maximum voltage rating of 100V and 0.1W power dissipation per resistor (0.4W total). Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the ceramic case enhances thermal and mechanical stability.

GS4A034121GBT Features

• Precision Performance: ±0.1% ratio tolerance ensures matched resistance for critical analog circuits.
• Robust Construction: Ceramic substrate and thin-film technology deliver low noise and high reliability.
• Wide Operating Range: Supports -55°C to 125°C (full power up to 70°C) for harsh environments.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Isolated Design: Independent resistors minimize crosstalk in multi-channel systems.
• Automotive-Grade Alternatives: While this model is not PPAP/automotive certified, similar variants are available for automotive use.

GS4A034121GBT Applications
