GS4B028200GDT Description

The GS4B028200GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 7-resistor bussed network is housed in an 8-pin narrow SOIC package, offering a compact footprint with 820Ω resistance per element and a tight ±2% absolute tolerance. Its thin-film technology ensures stable performance with a low ±50ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. The device operates within a -70°C to +125°C temperature range and supports a maximum voltage rating of 100V, with a 0.4W total power rating (0.05W per resistor). Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4B028200GDT Features

• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Precision Performance: ±2% tolerance and ±0.5% ratio tolerance ensure consistent signal integrity.
• Wide Operating Range: Functions reliably from -70°C to +125°C, even at derated power.
• Space-Efficient: Compact SOIC package (4.9mm × 5.99mm × 1.45mm) ideal for high-density layouts.
• Low TCR: ±50ppm/°C minimizes resistance drift under temperature variations.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its reliability suits industrial and telecom applications.
