GS4B012700JGT Description

The GS4B012700JGT from TT Electronics/IRC is a high-performance 7-resistor bussed network housed in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision and reliability, it features a 270Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±2%, ensuring consistent performance in demanding circuits. Its thin-film technology provides excellent stability with a low temperature coefficient of ±100ppm/°C, making it suitable for environments with fluctuating temperatures. The network operates within a temperature range of 70°C to 125°C and can handle a maximum voltage rating of 100V, with a total power rating of 0.4W (0.05W per resistor). The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case ensures durability and thermal resistance.

GS4B012700JGT Features

• Bussed Network Design: Simplifies circuit layout by connecting resistors in a common bus configuration.
• High Precision: ±5% absolute tolerance and ±2% ratio tolerance for reliable signal conditioning.
• Robust Construction: Ceramic SOIC package with a seated height of 1.63mm and tight dimensional tolerances (±0.1mm height, ±0.1mm length).
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Low TCR: ±100ppm/°C ensures minimal resistance drift under thermal stress.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for automated assembly compatibility.
