GS4A032742GAT Description

The GS4A032742GAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 27.4KΩ resistance and a tight ±2% absolute tolerance. The ±25ppm/°C temperature coefficient ensures stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical durability. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this network balances performance and reliability.

GS4A032742GAT Features

• Isolated Resistors: Four independent resistors (ISOL circuit design) for flexible circuit integration.
• Precision Tolerance: ±2% absolute tolerance and ±0.05% ratio tolerance for high-accuracy applications.
• Stable Performance: Low ±25ppm/°C TCR minimizes resistance drift under temperature variations.
• Robust Construction: Ceramic case with SOIC package ensures durability and efficient heat dissipation.
• Surface-Mount Design: Gull-wing termination and 1.27mm terminal pitch for easy PCB assembly.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.

GS4A032742GAT Applications

This resistor network is ideal for:

• Precision analog circuits requiring stable resistance ratios (e.g., instrumentation amplifiers, DACs/ADCs).
• Industrial control systems where thermal stability and isolation are critical.
• Medical electronics demanding high reliability and low drift.
• Automotive subsystems (non-AECQ qualified) in sensor interfaces or signal conditioning.
• Telecommunication equipment for impedance matching and filtering.

Conclusion of GS4A032742GAT

The GS4A032742GAT excels in precision, thermal stability, and isolation, making it a superior choice for applications requiring tight tolerance and low TCR. Its ceramic SOIC package enhances durability, while the thin-film technology ensures consistent performance. Though not PPAP or automotive-qualified, it is well-suited for industrial, medical, and telecom designs where accuracy and reliability are paramount. Engineers will appreciate its balance of performance and compact form factor (4.9mm x 5.99mm x 1.45mm), ideal for space-constrained PCBs.
