GS4A031911DT

GS4A031911DT Description

The GS4A031911DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.91 kΩ resistance and an ultra-tight ±0.5% tolerance. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift across a broad operating range of 70°C to 125°C, making it suitable for environments requiring thermal stability. Encased in a rectangular ceramic SOIC package, the network offers 0.1W power dissipation per resistor (0.4W total) and a 100V maximum voltage rating, with gull-wing terminations for reliable surface-mount assembly.

GS4A031911DT Features

• Precision Performance: Thin-film technology delivers ±0.5% absolute tolerance and ±25 ppm/°C TCR for critical analog circuits.
• Robust Construction: Ceramic case enhances thermal management and durability in harsh conditions.
• Isolated Design: Four independent resistors (non-bussed) enable flexible circuit design.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight dimensional tolerances (±0.1mm height/length).
