GS4A0238R3DDT Description

The GS4A0238R3DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 38.3Ω resistance and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50ppm/°C, making it stable under thermal stress. 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, suitable for high-reliability circuits.

GS4A0238R3DDT Features

• Precision Performance: ±0.5% tolerance and ±50ppm/°C TCR ensure minimal drift.
• Robust Construction: Ceramic case enhances thermal and mechanical durability.
• Isolated Design: Four independent resistors (non-bussed) for flexible circuit integration.
• Surface-Mount Ready: Gull-wing termination and 1.27mm pitch for easy PCB assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• High-Temperature Operation: Rated up to 125°C, ideal for harsh environments.
