GS4A032001DT Description

The GS4A032001DT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding applications requiring stable performance under varying conditions. Housed in an 8-pin narrow SOIC ceramic package, it features 2KΩ thin-film resistors with an absolute tolerance of ±0.5% and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical stability.

GS4A032001DT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Precision: ±0.5% tolerance and ±25ppm/°C TCR ensure consistent performance in temperature-sensitive environments.
• Robust Construction: Ceramic SOIC package offers superior thermal dissipation and durability compared to plastic alternatives.
• Automation-Friendly: 1.27mm terminal pitch and gull-wing leads optimize compatibility with pick-and-place systems.
• Wide Operating Range: Rated for -70°C to +125°C, making it ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Non-RoHS Compliance: Suitable for legacy or niche applications requiring non-compliant materials.

GS4A032001DT Applications

This resistor network excels in:

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to low TCR and tight tolerance.
• Signal Conditioning: Isolated resistors minimize crosstalk in sensor interfaces or instrumentation amplifiers.
• Power Supply Feedback Networks: Stable performance under thermal stress ensures reliable voltage regulation.
• Industrial Controls: Ceramic packaging withstands harsh environments with high vibration or temperature swings.
• Legacy Electronics Repair: Non-RoHS compliance allows direct replacement in older systems.
