GS4A031403DT Description

The GS4A031403DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 140KΩ resistance value with an ultra-tight ±0.5% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of 70°C to 125°C. The thin-film technology delivers superior accuracy and reliability, while the ceramic case style enhances thermal and mechanical durability. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this component is engineered for precision signal conditioning and voltage division in compact, surface-mount designs.

GS4A031403DT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Stability: ±25ppm/°C TCR and 0.5% tolerance ensure consistent performance in temperature-sensitive environments.
• Robust Construction: Ceramic substrate and gull-wing termination provide excellent thermal dissipation and solder joint reliability.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth) for high-density PCB layouts.
• Wide Operating Range: Rated for 125°C maximum temperature, suitable for industrial and instrumentation applications.
• Surface-Mount Ready: SOIC package with 1.27mm terminal pitch simplifies automated assembly.
