GS4B022802CBT Description

The GS4B022802CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for BUS circuit applications. Housed in an 8-pin SOIC ceramic package, it offers a 28KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this surface-mount (SMD) network is engineered for reliability in demanding environments. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4B022802CBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for signal integrity-critical applications.
• Ceramic SOIC Package: Superior heat dissipation and mechanical robustness compared to plastic alternatives.
• BUS-Optimized Design: Ideal for address/data bus termination in digital systems.
• Tight Tolerance & Low TCR: ±0.25% tolerance and ±50ppm/°C ensure minimal drift under thermal stress.
• High Voltage Handling: 100V rating suits industrial and instrumentation use.
• RoHS Non-Compliant: Suitable for legacy or exempted applications requiring leaded components.

GS4B022802CBT Applications

• Digital Systems: Bus termination for FPGAs, ASICs, and memory interfaces.
• Industrial Controls: Precision voltage division in PLC modules and sensor circuits.
• Test & Measurement Equipment: Stable reference networks in oscilloscopes and analyzers.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical electronic systems.
• Aerospace & Defense: High-reliability analog signal conditioning (derated for extreme temps).

Conclusion of GS4B022802CBT

The GS4B022802CBT excels in precision analog and digital circuits where low drift, high voltage tolerance, and compact packaging are critical. While not PPAP or automotive-qualified, its ceramic construction and thin film technology make it a standout for industrial, telecom, and high-end consumer electronics. Engineers will appreciate its balance of performance and durability, particularly in dense PCB layouts requiring stable, multi-resistor networks. For legacy or exempted designs, its non-RoHS compliance offers flexibility where alternative materials are restricted.
