GS8A021781DBT Description

The GS8A021781DBT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin SOIC ceramic package, it offers a 1.78KΩ resistance per resistor with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount (SMD) design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS8A021781DBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog/digital circuits.
• Isolated Resistor Network (ISOL): Each resistor is electrically isolated, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Superior heat dissipation and reliability vs. plastic alternatives.
• Tight Tolerances: 0.5% resistance tolerance and ±50ppm/°C TCR ensure accuracy in precision instrumentation.
• Compact SOIC-16 Footprint: 9.91mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• High Voltage Handling: 100V rating supports industrial and telecom applications.
