GS4B011302FAT Description

The GS4B011302FAT 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 13KΩ resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal performance.

GS4B011302FAT Features

• Precision Thin Film Technology: Delivers low noise and high stability, ideal for analog signal conditioning.
• Ceramic Case: Superior heat dissipation and mechanical robustness compared to polymer-based networks.
• BUS Circuit Designator: Optimized for bus termination, pull-up/pull-down networks, and voltage division.
• Space-Efficient SOIC Package: Compact 4.9mm × 5.99mm × 1.45mm footprint with ±0.1mm length/height tolerances.
• Automotive-Grade Alternatives Available: While this variant is non-automotive (PPAP: No), TT Electronics offers compliant versions for harsh environments.

GS4B011302FAT Applications

This resistor network excels in:

1. Industrial Control Systems: Precision voltage dividers in PLCs and sensor interfaces.
2. Telecommunications: Impedance matching and termination for high-speed data lines.
3. Medical Electronics: Stable reference circuits in diagnostic equipment.
4. Test & Measurement: Calibration networks requiring low TCR (temperature coefficient of resistance).
5. Power Management: Distributed load balancing in DC-DC converters.

Conclusion of GS4B011302FAT

The GS4B011302FAT stands out for its ceramic construction, tight tolerances, and thin film reliability, making it a superior choice over epoxy-coated networks in high-temperature or precision-critical designs. While non-RoHS compliant, its performance in industrial and telecom applications justifies its use where regulatory exemptions apply. For engineers seeking stable, space-saving resistor arrays, this model offers a compelling blend of precision and durability.
