GS4B012492BBT Description

The GS4B012492BBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for demanding electronic applications. Encased in a ceramic SOIC-8 package, it features a 24.9KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network is ideal for precision analog and digital circuits. Its gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly, while the ceramic substrate enhances thermal performance and durability.

GS4B012492BBT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic case with rectangular SOIC-8 package (4.9mm × 5.99mm × 1.45mm) and ±0.1mm dimensional tolerances.
• Optimized Power Handling: 0.4W total (0.05W per resistor) with derating up to 125°C.
• Automation-Friendly: Gull-wing leads and tube packaging for efficient pick-and-place assembly.
• Broad Compatibility: BUS circuit designator simplifies integration into bus termination, voltage division, and feedback networks.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and test equipment (not automotive-qualified).

GS4B012492BBT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, DAC/ADC reference networks, and sensor signal conditioning.
• Digital Systems: Bus termination for high-speed data lines (e.g., SPI, I²C) to minimize reflections.
• Test & Measurement: Calibration equipment and instrumentation requiring long-term stability.
• Power Management: Feedback loops in DC-DC converters or LDO regulators.
• Industrial Controls: PLCs and motor drives where temperature resilience is critical.

Conclusion of GS4B012492BBT

The GS4B012492BBT combines thin-film precision, ceramic reliability, and compact SMD form factor to address high-accuracy circuit design challenges. Its low TCR, tight tolerance, and robust power handling make it superior to standard thick-film networks in environments demanding thermal and electrical consistency. While not PPAP-capable or automotive-grade, it is a cost-effective solution for industrial and telecom applications requiring repeatable performance. Engineers will value its drop-in compatibility with SOIC footprints and its ability to reduce component count in space-constrained designs.
