GS4A021003JT

GS4A021003JT Description

The GS4A021003JT 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 package features four isolated thin-film resistors, each rated at 100KΩ with a ±5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. The device delivers a 0.1W (1/10W) power rating per resistor (0.4W total) and supports a maximum voltage rating of 100V, making it suitable for moderate-power circuits. Its SOIC (SOIC-C series) ceramic case offers superior thermal and mechanical stability compared to standard plastic packages.

GS4A021003JT Features

• Isolated Resistors: Four independent 100KΩ resistors with no shared substrate, reducing crosstalk in sensitive circuits.
• High-Temperature Stability: Operates reliably up to 125°C with derated performance up to 70°C.
• Precision Thin-Film Technology: Delivers ±50ppm/°C TCR and 5% tolerance for consistent performance.
• Robust Construction: Ceramic package ensures durability and superior heat dissipation vs. polymer-based networks.
• Surface-Mount Design: Gull-wing terminals with 1.27mm pitch for compatibility with automated PCB assembly.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where automotive-grade certification is not required.

GS4A021003JT Applications

This resistor network excels in:

• Signal Conditioning: Isolated resistor arrays for op-amp feedback networks or voltage dividers in sensor interfaces.
