GS4A031871DT Description

The GS4A031871DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 1.87 kΩ and an absolute tolerance of ±0.5%. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift, making it suitable for precision circuits. The network operates within a temperature range of 70°C to 125°C and offers a maximum voltage rating of 100V, with a power rating of 0.1W per resistor (0.4W total). The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.

GS4A031871DT Features

• High Precision: Tight tolerance (±0.5%) and low TCR (±25 ppm/°C) for accurate signal conditioning.
• Robust Construction: Ceramic SOIC package ensures durability and thermal performance.
• Isolated Resistors: Four independent 1.87 kΩ resistors for flexible circuit design.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch for easy assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm).
