GS4A038872JAT Description

The GS4A038872JAT 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 resistance value of 88.7 kΩ and a ±5% absolute tolerance, ensuring consistent performance. The ±25 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for environments with fluctuating temperatures (rated for 70°C to 125°C). With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. Its SOIC package (4.9mm x 5.99mm x 1.45mm) offers compact surface-mount compatibility, while gull-wing terminals facilitate secure PCB attachment.

GS4A038872JAT Features

• Isolated Resistors: Four independent 88.7 kΩ resistors with ±0.05% ratio tolerance for precise voltage division.
• Stable Performance: ±25 ppm/°C TCR ensures minimal resistance variation across the -70°C to +125°C operating range.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• High Voltage Tolerance: 100V rating per resistor, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Compact & Reliable: SOIC-C series package with 1.27mm terminal pitch optimizes space on densely populated PCBs.
• Non-RoHS Compliant: Suitable for legacy or specialized applications where RoHS exemptions apply.

GS4A038872JAT Applications
