GS8A022872BT Description

The GS8A022872BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin SOIC ceramic package, it features 28.7KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact, surface-mount designs.

GS8A022872BT Features

• Precision Thin Film Technology: Delivers 0.1% tolerance and ±50ppm/°C TCR for critical accuracy.
• Robust Ceramic Package: SOIC-16 case with gull-wing terminals ensures mechanical durability and ease of soldering.
• High Isolation (ISOL): Independent resistors minimize interference in multi-channel systems.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suited for harsh environments.
• Compact Dimensions: 9.91mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm) for space-constrained PCBs.
• Surface-Mount Ready: 1.27mm terminal pitch simplifies automated assembly.
