GS4B027501CT

GS4B027501CT Description

The GS4B027501CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for demanding applications, it features a 7.5KΩ resistance per element with an exceptional ±0.25% absolute tolerance and a low ±50ppm/°C temperature coefficient. The thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C derated, 125°C max operating). With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4B027501CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic SOIC package with 1.45mm height and 4.9mm × 5.99mm footprint, tolerances ±0.1mm (L/H) and ±0.2mm (D).
• Optimized Power Handling: 0.4W total (0.05W per resistor) derated up to 125°C.
• Bussed Network: 7 resistors with a common bus, simplifying circuit design.
• Thin-Film Technology: Low noise and high stability vs. thick-film alternatives.
• Surface-Mount Ready: 1.27mm pitch gull-wing leads for automated assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation.
