GS4B019090CT Description

The GS4B019090CT 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 909Ω resistance per element with an ultra-tight ±0.25% absolute tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers low noise and high reliability, while the 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.

GS4B019090CT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances for precise mounting.
• Bussed Network Design: 7 resistors tied to a common bus (BUS circuit designator), simplifying layout in voltage-divider or pull-up/down applications.
• High Precision: ±0.25% tolerance and ±100ppm/°C TCR for critical analog/digital signal conditioning.
• Wide Temperature Range: Derated power up to 125°C, ideal for industrial or automotive-adjacent environments (though not PPAP/automotive-certified).
• Thin-Film Reliability: Low parasitic effects and stable performance vs. thick-film alternatives.

GS4B019090CT Applications

• Voltage Division: Precision dividers in ADC/DAC reference circuits or sensor interfaces.
• Bus Termination: Pull-up/down networks for I²C, SPI, or other digital buses.
• Industrial Controls: Signal conditioning in PLC modules, test equipment, or power management ICs.
• Consumer Electronics: Compact solutions for audio processing, display drivers, or power supplies.

Conclusion of GS4B019090CT

The GS4B019090CT excels in space-constrained, high-reliability designs requiring tight tolerance and thermal stability. Its ceramic construction and thin-film technology outperform standard epoxy-based networks in harsh environments, while the bussed architecture reduces component count. Though not RoHS-compliant, it remains a top choice for non-automotive industrial and instrumentation applications demanding precision and durability. Engineers should verify compatibility for high-voltage or mission-critical systems due to its unconfirmed part status.
