GS4A021101FAT

GS4A021101FAT Description

The GS4A021101FAT 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 1.1 kΩ resistance and a tight ±1% absolute tolerance. Its ±50 ppm/°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. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while the gull-wing termination facilitates reliable surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances performance and durability.

GS4A021101FAT Features

• Isolated Resistors: Four independent 1.1 kΩ resistors with ±1% tolerance and ±0.05% ratio tolerance for precision matching.
• Stable Performance: Thin-film technology and ±50 ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic case enhances thermal and mechanical resilience.
• Surface-Mount Ready: Gull-wing leads (1.27mm pitch) simplify PCB integration.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Compact Dimensions: 4.9mm length, 5.99mm depth, 1.45mm height (tolerances ±0.1mm/±0.2mm).

GS4A021101FAT Applications

Ideal for precision analog and digital circuits requiring stable resistance values, such as:

• Voltage dividers in sensor interfaces.
• Biasing networks for amplifiers and ADCs.
• Signal conditioning in industrial control systems.
• Medical instrumentation where low drift is critical.
• Automotive subsystems (non-AECQ qualified, suitable for prototyping).

Conclusion of GS4A021101FAT

The GS4A021101FAT excels in applications demanding high accuracy, thermal stability, and compactness. Its isolated thin-film resistors, ceramic encapsulation, and tight tolerances make it a superior choice over standard arrays in precision electronics. While not PPAP or automotive-qualified, it is well-suited for industrial, medical, and prototyping use. Engineers will appreciate its reliability in harsh environments and ease of integration into space-constrained designs.
