GS8A021781FBT Description

The GS8A021781FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 1.78KΩ resistance per element with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin SOIC ceramic package, it offers 0.1W power dissipation per resistor (0.8W total) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the isolated (ISOL) circuit configuration enhances signal integrity in multi-channel systems.

GS8A021781FBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic SOIC Package: Provides superior thermal management and mechanical robustness compared to plastic alternatives.
• Isolated Resistor Network (ISOL): Each resistor is electrically independent, ideal for multi-point signal isolation.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Automation-Friendly: Gull-wing SMD terminals and ±0.1mm length/height tolerances ensure consistent PCB placement.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.

GS8A021781FBT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
