GS8A028661CAT Description

The GS8A028661CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding applications requiring tight tolerance and stability. Built with thin-film technology on a ceramic substrate, it offers excellent thermal performance with a ±50ppm/°C temperature coefficient and 0.25% absolute tolerance. Each resistor features an 8.66KΩ value, rated for 0.1W (1/10W) power dissipation per element (0.8W total), and operates within a 70°C to 125°C derated range, with a maximum 125°C operating temperature. The 100V maximum voltage rating and gull-wing termination ensure reliable surface-mount integration.

GS8A028661CAT Features

• Precision Performance: ±0.25% absolute tolerance and ±0.05% ratio tolerance for critical signal conditioning.
• Robust Construction: Ceramic case and thin-film technology provide low noise, high stability, and durability.
• Thermal Resilience: Operates up to 125°C with derated power handling at elevated temperatures.
• Compact & Reliable: 9.91mm x 5.99mm x 1.45mm SOIC package with ±0.1mm length/height tolerances for consistent PCB fit.
• Isolated Design: Independent resistors (no common node) for flexible circuit design in isolation-sensitive applications.

GS8A028661CAT Applications

Ideal for precision analog circuits, including:

• Medical instrumentation (patient monitoring, diagnostic equipment).
• Industrial automation (sensor signal conditioning, PLCs).
• Test & measurement systems (calibration, data acquisition).
• Aerospace & defense (avionics, ruggedized electronics).
• High-reliability consumer electronics (audio amplifiers, reference voltage networks).

Conclusion of GS8A028661CAT

The GS8A028661CAT excels in environments demanding high accuracy, thermal stability, and isolation. Its ceramic SOIC package, thin-film resistors, and tight tolerances make it superior to standard networks in precision-critical designs. While not RoHS-compliant and unconfirmed for automotive use, it remains a top choice for industrial, medical, and aerospace applications where performance outweighs compliance constraints. Engineers benefit from its repeatable performance, compact footprint, and derated power handling in extended temperature ranges.
