GS4A021272CBT Description

The GS4A021272CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 12.7KΩ and an absolute tolerance of ±0.25%. The device operates over a wide temperature range (70°C to 125°C) with a ±50ppm/°C temperature coefficient, ensuring stability in varying environmental conditions. Its 0.1W (1/10) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust performance in surface-mount applications, with a compact footprint (4.9mm length × 5.99mm depth × 1.45mm height) and gull-wing termination for reliable PCB mounting.

GS4A021272CBT Features

• High Precision: ±0.25% absolute tolerance and ±0.1% ratio tolerance for critical signal conditioning.
• Isolated Resistors: Four independent thin-film resistors in a single package, reducing board space and improving signal integrity.
• Wide Temperature Range: Stable performance from 70°C to 125°C with derated power handling.
• Robust Construction: Ceramic case and SOIC package ensure durability and thermal stability.
• Low TCR: ±50ppm/°C minimizes resistance drift under thermal stress.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch for easy PCB assembly.
