GS4A034872DT

GS4A034872DT Description

The GS4A034872DT 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 48.7 kΩ resistance and an ultra-tight ±0.5% tolerance. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of 70°C to 125°C, making it ideal for stable performance in thermally variable environments. Encased in a rectangular ceramic SOIC package, it offers excellent thermal stability and durability, with a maximum voltage rating of 100V and a power rating of 0.1W per resistor (0.4W total).

GS4A034872DT Features

• Precision Performance: Thin-film technology with ±0.5% absolute tolerance and ±25 ppm/°C TCR for high accuracy.
• Robust Construction: Ceramic case (SOIC-C series) ensures superior thermal and mechanical stability.
• Isolated Resistors: Four independent 48.7 kΩ resistors with gull-wing terminations for easy surface-mount assembly.
• Wide Temperature Range: Derated power operation up to 125°C, suitable for industrial and automotive-adjacent applications.
• Compact & Reliable: 4.9mm × 5.99mm footprint with 1.45mm height, adhering to tight tolerances (±0.1mm length/height, ±0.2mm depth).

GS4A034872DT Applications

This resistor network excels in precision circuits requiring stable resistance values under thermal stress, such as:
