GS8A021273BT

GS8A021273BT Description

The GS8A021273BT 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 127K Ohm resistance value with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin SOIC ceramic package, it offers 0.8W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its isolated (ISOL) circuit configuration enhances signal integrity in noise-sensitive environments.

GS8A021273BT Features

• Precision Thin Film Technology: Delivers 0.1% tolerance and ±50ppm/°C TCR for critical analog applications.
• Robust Ceramic Package: Ensures thermal stability and mechanical durability in harsh conditions.
• High Power Handling: 0.8W total (0.1W per resistor) with derating up to 125°C.
• Isolated Resistor Network (ISOL): Minimizes crosstalk, ideal for multichannel isolation.
• Surface-Mount SOIC-16: Compact footprint (9.91mm × 5.99mm × 1.45mm) with 1.27mm pitch for high-density layouts.
• Non-Automotive Grade: Suitable for industrial, medical, and test equipment where precision is paramount.

GS8A021273BT Applications
