GS4B031871JCT Description

The GS4B031871JCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 1.87KΩ resistance per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this network is ideal for signal conditioning, voltage division, and bus termination in compact PCB designs. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable soldering in automated assembly processes.

GS4B031871JCT Features

• 7-resistor network with 1.87KΩ ±5% tolerance, ensuring consistent signal integrity.
• Thin film technology for low noise, high stability, and precision (±25ppm/°C TCR).
• Ceramic SOIC-8 case with 4.9mm × 5.99mm footprint and 1.45mm profile, optimized for space-constrained designs.
• Gull-wing SMD termination for robust mechanical and electrical connections.
• Wide operating range: -55°C to +125°C (derated power above 70°C).
• Non-automotive grade (PPAP: No) but suitable for industrial and telecom applications.
• Tube packaging for secure handling and storage.

GS4B031871JCT Applications

This resistor network excels in:

• Bus termination (designated "BUS") for impedance matching in high-speed digital circuits.
• Analog signal processing (e.g., op-amp feedback networks, DAC/ADC interfaces).
• Power supply dividers in embedded systems and IoT devices.
• Test & measurement equipment requiring stable, low-drift resistance values.
• Industrial control PCBs where ceramic packaging ensures durability under thermal stress.

Conclusion of GS4B031871JCT

The GS4B031871JCT combines precision, compactness, and reliability, making it a standout choice for high-density electronics. Its thin film construction, tight TCR, and robust ceramic package outperform comparable thick-film networks in thermal stability and longevity. While not RoHS-compliant, it remains a cost-effective solution for non-consumer applications demanding consistent performance under harsh conditions. Engineers will appreciate its balance of electrical specs, form factor, and manufacturability in telecom, industrial, and instrumentation designs.
