GS4B031181JBT Description

The GS4B031181JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 7-resistor network features a 1.18KΩ resistance value 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). Encased in a ceramic SOIC package, it offers a compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing terminations for reliable surface-mount (SMD) assembly. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it is ideal for signal conditioning, voltage division, and bus termination in industrial and telecom systems.

GS4B031181JBT Features

• Precision Thin Film Technology: Delivers low noise and high stability (±25ppm/°C) for critical analog/digital circuits.
• Robust Ceramic Construction: Enhances thermal dissipation and mechanical durability in harsh environments.
• Optimized Power Handling: 0.4W total rating (1/20W per resistor) ensures reliability in compact designs.
• Automation-Friendly Packaging: Supplied in tubes for efficient pick-and-place assembly.
• Wide Operating Range: Supports -55°C to +125°C (derated above 70°C) for industrial applications.
• Non-Automotive (PPAP No): Suitable for non-automotive precision electronics.

GS4B031181JBT Applications

• Bus Termination Networks: Ensures signal integrity in high-speed data lines (e.g., DDR memory, CAN buses).
• Voltage Dividers: Used in ADC/DAC reference circuits and sensor interfaces.
• Industrial Control Systems: Reliable performance in PLCs, motor drives, and power supplies.
• Telecom Infrastructure: Signal conditioning in base stations and networking equipment.
• Test & Measurement: Precision instrumentation requiring stable resistance values.

Conclusion of GS4B031181JBT

The GS4B031181JBT stands out for its thin-film accuracy, compact SOIC footprint, and ceramic-enhanced reliability, making it a superior choice over thicker-film or less stable alternatives. While non-compliant with EU RoHS, its 5% tolerance and ±25ppm/°C TCR cater to cost-sensitive yet performance-critical designs. Ideal for engineers seeking a balance of precision, power efficiency, and space savings in industrial, telecom, and embedded systems.
