GS4B038661FT Description

The GS4B038661FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a thin-film technology construction with a ±1% tolerance and ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The network offers a total resistance of 8.66KΩ per element, with each resistor rated for 0.05W (1/20W) and a combined power rating of 0.4W. Its 100V maximum voltage rating and gull-wing termination make it suitable for high-reliability circuits.

GS4B038661FT Features

• Ceramic case (SOIC package) for enhanced thermal stability and durability.
• Bussed network topology simplifies PCB layout in bus-line applications.
• Low TCR (±25ppm/°C) ensures minimal resistance drift under thermal stress.
• Precision tolerance (±1%) for critical analog/digital signal conditioning.
• Compact dimensions (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height/length).
• Non-automotive (PPAP: No) but suited for industrial and telecom environments.
• Non-RoHS compliant, ideal for legacy or specialized designs.
