GS4B022742FT

GS4B022742FT Description

The GS4B022742FT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a ceramic SOIC package, this thin-film resistor network offers a 27.4KΩ resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its 8-pin narrow SOIC (SOIC-C) configuration with gull-wing terminations facilitates easy surface-mount assembly, while the 0.05W (1/20W) power rating per resistor and 0.4W total power handling make it suitable for low-power, high-density designs. The 100V maximum voltage rating and ceramic substrate enhance reliability in harsh environments.

GS4B022742FT Features

• Bussed Network Topology: Simplifies PCB layout by connecting resistors in a shared configuration.
• Ceramic Case (SOIC): Provides superior thermal performance and mechanical robustness.
• Thin-Film Technology: Delivers precision (±1%) and low TCR (±50ppm/°C) for stable operation.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Wide Temperature Range: Derated power up to 125°C, ideal for industrial and automotive-adjacent applications.
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints and compatibility with automated assembly.

GS4B022742FT Applications

This resistor network excels in:

• Voltage Division Circuits: Precision dividers in sensor interfaces or ADCs.
• Bus Termination: Signal integrity in high-speed digital systems (e.g., SPI, I²C).
• Industrial Controls: Stable performance in PLCs, motor drives, and power supplies.
• Test & Measurement Equipment: Low-drift reference networks for calibration.
• Aerospace & Defense: Ceramic construction suits rugged, high-reliability environments (though non-automotive/PPAP).

Conclusion of GS4B022742FT

The GS4B022742FT stands out for its ceramic SOIC package, bussed design, and thin-film precision, offering a balance of miniaturization, thermal resilience, and electrical stability. While not PPAP-certified or automotive-grade, its wide temperature range and low TCR make it a robust choice for industrial, instrumentation, and high-reliability applications where consistent performance is critical. Engineers will appreciate its ease of integration and repeatable accuracy in space-constrained designs.
