GS4B021912CT Description

The GS4B021912CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 19.1KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, this thin-film ceramic-based network ensures stability and accuracy in critical circuits. The SOIC-C series construction offers robust performance with a 100V maximum voltage rating, 0.4W total power dissipation, and derated operation up to 125°C. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly.

GS4B021912CT Features

• Precision Performance: 0.25% tolerance and ±50ppm/°C TCR for stable operation in temperature-variable environments.
• Durable Construction: Ceramic substrate with rectangular SOIC package (4.9mm × 5.99mm × 1.45mm) ensures mechanical and thermal resilience.
• Optimized Power Handling: 0.05W per resistor (0.4W total) with derating from 70°C to 125°C.
• Bussed Topology: Simplified BUS circuit designator reduces PCB layout complexity for voltage-divider or pull-up/down networks.
• Industrial-Grade Reliability: Non-automotive but suitable for industrial controls, test equipment, and precision instrumentation.

GS4B021912CT Applications

• Voltage Division: Ideal for ADC/DAC reference networks due to matched resistor ratios.
• Signal Conditioning: Stable performance in sensor interfaces and feedback loops.
• Power Management: Used in load-sharing circuits or bias networks for op-amps.
• Aerospace/Defense: Non-RoHS version suits applications with legacy compliance requirements.

Conclusion of GS4B021912CT

The GS4B021912CT excels in precision analog designs where low TCR, tight tolerance, and compact SOIC footprint are critical. Its ceramic thin-film technology and bussed architecture make it a superior choice over thicker-film or discrete alternatives in space-constrained, high-reliability systems. While not PPAP-capable, it is a cost-effective solution for industrial and instrumentation markets.
