GS4B0190R9JGT

GS4B0190R9JGT Description

The GS4B0190R9JGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 90.9Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±2%, ensuring consistent performance in matched circuits. The thin-film technology on a ceramic substrate delivers excellent stability, with a temperature coefficient of ±100ppm/°C across a wide operating range of -70°C to +125°C. Its 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power, high-density designs. The 100V maximum voltage rating and gull-wing termination ensure reliable surface-mount integration.

GS4B0190R9JGT Features

• Bussed Network Design: 7 resistors connected in a common bus configuration, simplifying PCB layout.
• Ceramic SOIC Package: Robust 4.9mm × 5.99mm × 1.45mm form factor with ±0.1mm length/height tolerances for precise mounting.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±5% absolute, ±2% ratio).
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
