GS8A028201CAT Description

The GS8A028201CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC ceramic package, it features 8.2KΩ thin-film resistors with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring superior matching accuracy. The device operates over a wide temperature range of 70°C to 125°C with a ±50ppm/°C temperature coefficient, making it stable under thermal stress. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.8W total) cater to precision analog and signal conditioning circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS8A028201CAT Features

• High Precision: ±0.25% absolute tolerance and ±0.05% ratio tolerance for critical matching applications.
• Robust Construction: Ceramic case with SOIC package (9.91mm × 5.99mm × 1.45mm) ensures durability and thermal stability.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power.
• Low TCR: ±50ppm/°C minimizes resistance drift across temperatures.
• Isolated Design: Independent resistors (no common terminal) for flexible circuit configurations.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for automated assembly.

GS8A028201CAT Applications

This resistor network excels in:

• Precision voltage dividers and bridge circuits requiring tight tolerance matching.
• Medical instrumentation and test/measurement equipment where stability is critical.
• Industrial control systems needing high-voltage isolation (up to 100V).
• Communication infrastructure (e.g., RF amplifiers, filters) demanding low thermal drift.
• Automotive sensors (non-AECQ qualified) in non-safety-critical roles.

Conclusion of GS8A028201CAT

The GS8A028201CAT stands out for its precision, isolation, and thermal performance, making it ideal for high-reliability analog designs. While not PPAP or automotive-qualified, its ceramic construction and thin-film technology offer superior accuracy over standard networks. Engineers will value its low TCR, tight tolerances, and compact SOIC footprint for space-constrained, precision-critical applications.
