GS4B027321FT Description

The GS4B027321FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 7.32KΩ resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. The thin-film technology delivers superior accuracy and reliability, while the 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) make it suitable for demanding circuits. Its gull-wing termination and surface-mount design enable easy PCB integration, with dimensions of 4.9mm (L) x 5.99mm (D) x 1.45mm (H) and tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4B027321FT Features

• Ceramic SOIC-C case for robust thermal and mechanical stability.
• Bussed network (BUS) with 7 resistors, ideal for voltage division or pull-up/down applications.
• 1% absolute tolerance and ±50ppm/°C TCR for precision signal conditioning.
• Thin-film technology ensures low noise and high reliability.
• 0.4W total power rating (0.05W per resistor) with derating up to 125°C.
• 100V maximum voltage rating for industrial-grade designs.
• Gull-wing leads and 1.27mm pitch for compatibility with automated assembly.
• Non-automotive (PPAP No) and EU RoHS non-compliant—verify for specific regulatory needs.
