GS8A021272BT

GS8A021272BT Description

The GS8A021272BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 12.7KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 16-pin SOIC ceramic package, it offers 0.8W total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for precision analog and mixed-signal circuits. The gull-wing SMD termination and 1.27mm pitch facilitate reliable surface-mount assembly, while its isolated (ISOL) circuit design minimizes crosstalk in multi-channel systems.

GS8A021272BT Features

• High Precision: 0.1% tolerance and ±50ppm/°C TCR for critical accuracy.
• Robust Construction: Ceramic SOIC case ensures durability and thermal stability.
• Isolated Design: Reduces interference in multi-resistor configurations.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch for automated PCB assembly.
• Low Noise: Thin-film technology minimizes parasitic effects in sensitive circuits.

GS8A021272BT Applications
