GS4B023902JT

GS4B023902JT Description

The GS4B023902JT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision surface-mount applications. It features a 39KΩ resistance per element with a ±5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. The thin-film technology delivers superior accuracy and reliability, while the 100V maximum voltage rating and 0.4W total power dissipation make it suitable for demanding circuits. The gull-wing termination and 1.27mm terminal pitch ensure compatibility with automated PCB assembly processes.

GS4B023902JT Features

• Ceramic case (SOIC package) for enhanced thermal stability and durability.
• Bussed (BUS) circuit design simplifies PCB layout in multi-resistor applications.
• Low TCR (±50ppm/°C) minimizes resistance drift under temperature fluctuations.
• High power rating (0.4W total, 0.05W per resistor) for robust performance.
• Compact dimensions (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm height/length).
• Non-automotive (PPAP: No) but suitable for industrial and commercial electronics.
• Non-RoHS compliant, ideal for legacy or specialized designs requiring ceramic substrates.
