GS4B021210FFT

GS4B021210FFT Description

The GS4B021210FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. It features a 121Ω resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. The thin-film technology delivers a low ±50ppm/°C temperature coefficient, making it suitable for stable operation across a -70°C to +125°C derated power range. With a 100V maximum voltage rating and 0.4W total power dissipation, this network balances compactness (4.9mm × 5.99mm × 1.45mm) with robustness. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB assembly.

GS4B021210FFT Features

• Ceramic substrate for enhanced thermal stability and durability.
• Bussed (BUS) topology simplifies circuit design by interconnecting resistors.
• 0.05W (1/20W) power rating per resistor, derated up to 125°C.
• Low TCR (±50ppm/°C) minimizes resistance drift under temperature fluctuations.
• 1% tolerance ensures precision in voltage division and current sensing.
• SOIC package (tube-packed) optimizes space in high-density layouts.
• Non-automotive and non-PPAP compliant, ideal for industrial/consumer electronics.

GS4B021210FFT Applications

This resistor network excels in:

• Voltage dividers and pull-up/pull-down arrays in analog/digital circuits.
• Signal conditioning for sensors, ADCs, and DACs requiring matched resistances.
• Power management modules where stable, low-drift resistance is critical.
• Industrial control systems and test equipment demanding repeatable performance.
• Consumer electronics (e.g., audio hardware, displays) benefiting from compact, high-reliability components.

Conclusion of GS4B021210FFT

The GS4B021210FFT stands out for its ceramic construction, tight tolerances, and bussed design, offering superior thermal and electrical stability compared to polymer-based networks.
