GS4B017322GFT Description

The GS4B017322GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it offers a 73.2KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance. The device operates over a wide temperature range of -70°C to +125°C, derating power up to 125°C, and features a ±100ppm/°C temperature coefficient for stable performance in demanding environments. Its SOIC-C series construction ensures robust mechanical and thermal reliability, with a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly.

GS4B017322GFT Features

• Ceramic case for superior thermal stability and durability.
• Bussed (BUS) design simplifies circuit routing in multi-resistor applications.
• Low TCR (±100ppm/°C) ensures minimal resistance drift across temperatures.
• Compact dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• RoHS non-compliant (suitable for legacy or exempted applications).
• Tube packaging for automated handling and reel-free storage.

GS4B017322GFT Applications

Ideal for precision analog and digital circuits requiring matched resistor networks, such as:

• Voltage dividers in sensor interfaces.
• Pull-up/pull-down networks in microcontrollers and FPGAs.
• Signal conditioning in industrial automation and test equipment.
• A/D and D/A converter reference networks.
  The SOIC footprint and bussed topology make it particularly useful in space-constrained PCBs where consistent resistance matching is critical.

Conclusion of GS4B017322GFT

The GS4B017322GFT combines high precision, thermal resilience, and compact form factor, making it a standout choice for engineers designing reliable electronics in harsh environments. Its ceramic construction and thin-film technology outperform polymer-based networks in stability, while the bussed configuration reduces component count. While not RoHS-compliant, it remains a robust solution for legacy or exempted systems demanding tight tolerance and low TCR.
