GS8B029090GBT

GS8B029090GBT Description

The GS8B029090GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Packaged in a 16-pin narrow SOIC (SOIC-C series), this bussed configuration integrates 15 thin-film resistors with a 909Ω resistance value and a tight ±2% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stability across a wide operating temperature range of -70°C to +125°C, making it suitable for demanding environments. The 0.05W (1/20) power rating per resistor and 0.8W total power rating provide reliable performance in compact designs. With a 100V maximum voltage rating and gull-wing termination, it is optimized for surface-mount assembly in space-constrained PCBs.

GS8B029090GBT Features

• Ceramic substrate for enhanced thermal and mechanical durability.
• Thin-film technology delivers high precision (±2% tolerance) and low TCR (±50ppm/°C).
• Bussed network (15 resistors) simplifies circuit design in voltage-divider or pull-up/down applications.
• Narrow SOIC (SOIC-C) package (9.91mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances for consistent placement.
• 1.27mm terminal pitch ensures compatibility with automated PCB assembly.
• Wide temperature range (-70°C to +125°C) supports industrial and automotive-grade reliability (though not PPAP/automotive-certified).
• Non-RoHS compliant, suitable for legacy or specialized systems.

GS8B029090GBT Applications

Ideal for precision analog circuits, signal conditioning, and voltage division in:

• Test & measurement equipment requiring stable resistance under thermal stress.
• Industrial control systems where ceramic robustness mitigates vibration/thermal cycling.
• Communication infrastructure (e.g., line termination, impedance matching).
• Legacy electronics needing non-RoHS components.
  Outperforms polymer-based networks in high-temperature environments due to its ceramic construction and thin-film stability.

Conclusion of GS8B029090GBT

The GS8B029090GBT combines precision, durability, and compactness, making it a standout choice for engineers prioritizing thermal resilience and space efficiency. While not automotive-qualified, its wide temperature range and bussed design streamline complex circuits. Its non-RoHS status may limit use in modern eco-conscious designs but remains invaluable for specialized or high-reliability applications. For stable, high-density resistor networks, this model delivers exceptional value.
