GS4B031302FT

GS4B031302FT Description

The GS4B031302FT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a ceramic SOIC package, this thin-film resistor network offers a 13KΩ resistance per element with a tight ±1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Its 8-pin narrow SOIC (SOIC-C) form factor ensures compact PCB integration, while the gull-wing termination facilitates reliable surface-mount assembly. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it operates across a wide temperature range of -55°C to +125°C, with derated performance up to 125°C. The ceramic construction enhances thermal stability, making it ideal for environments requiring low drift and high reliability.

GS4B031302FT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±1% tolerance) for signal conditioning and voltage division.
• Robust Ceramic Package: Ensures superior thermal dissipation and mechanical durability compared to polymer-based networks.
• Bussed Configuration (BUS): Simplifies circuit design by interconnecting resistors, reducing component count in bus lines or pull-up/down networks.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C, suitable for industrial and automotive-grade prototypes (though not PPAP/automotive-certified).
• Compact & Reliable: 4.9mm x 5.99mm footprint with ±0.1mm length/height tolerances and 1.27mm terminal pitch for high-density layouts.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded soldering processes.

GS4B031302FT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, feedback networks in op-amp circuits.
• Industrial Control Systems: PLCs, sensor interfaces, and power management modules requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits, reference voltage networks.
• Legacy Electronics Repair: Non-RoHS compliance makes it a drop-in replacement for older designs.
• Prototyping & Breadboarding: Bussed design reduces wiring complexity in multi-channel systems.

Conclusion of GS4B031302FT

The GS4B031302FT stands out for its ceramic-encased reliability, precision thin-film performance, and space-saving SOIC packaging. While not suited for automotive-grade or RoHS-mandated designs, its low TCR, high voltage rating, and bussed topology make it a versatile choice for industrial, instrumentation, and legacy systems. Engineers will appreciate its balance of accuracy, power handling, and thermal resilience in compact applications.
