GS4B032742BBT Description

The GS4B032742BBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for demanding electronic applications. Encased in a ceramic SOIC-8 package, it offers a 27.4KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal performance and reliability.

GS4B032742BBT Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic case ensures durability and efficient heat dissipation.
• Compact & Reliable: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Optimized for SMT: Gull-wing leads with 1.27mm pitch for seamless PCB integration.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Low-Power Efficiency: 1/20W per resistor minimizes thermal load in dense layouts.
