GS4A021102GT

GS4A021102GT Description

The GS4A021102GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 11 kΩ resistance and a tight ±2% tolerance. Its ±50 ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it suitable for environments with fluctuating temperatures. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) offers a compact footprint, while the gull-wing termination facilitates reliable surface-mount assembly. Rated for 100 V maximum voltage and 0.1 W power dissipation per resistor, it combines durability with efficiency.

GS4A021102GT Features

• Isolated Resistors: Four independent 11 kΩ resistors in a single package, eliminating crosstalk.
• Stable Performance: ±50 ppm/°C TCR and 2% tolerance ensure precision in critical circuits.
