GS4B029760DT Description

The GS4B029760DT 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 976Ω resistance per element with an absolute tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact designs.

GS4B029760DT Features

• Ceramic SOIC-C Package: Enhances thermal performance and durability in harsh environments.
• Bussed Network (7 Resistors): Simplifies PCB layout for bus line applications.
• High Precision: ±0.5% tolerance and ±50ppm/°C TCR for critical analog/digital circuits.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Thin-Film Technology: Delivers low noise and long-term stability.
• Compact Dimensions: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Gull-Wing Termination: Facilitates automated assembly and strong solder joints.

GS4B029760DT Applications
