GS4B031271DDT Description

The GS4B031271DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 1.27KΩ configuration with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, this network offers excellent thermal stability and reliability. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The EU RoHS non-compliant status indicates specialized material use, while the tube packaging ensures safe handling and storage.

GS4B031271DDT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±25ppm/°C) for stable operation.
• Robust Ceramic Construction: Enhances thermal performance and durability in harsh environments.
• Compact SOIC-8 Package: Saves board space with 4.9mm length, 5.99mm depth, and 1.45mm height (±0.1mm tolerance).
• BUS Circuit Designator: Optimized for bus line termination and voltage division applications.
• Surface-Mount Gull Wing Terminals: Facilitates automated assembly with 1.27mm pitch spacing.
• Wide Operating Range: Rated for 125°C maximum temperature and derated power up to 125°C.

GS4B031271DDT Applications
