GS4B032211GFT Description

The GS4B032211GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 2.21KΩ resistance per element and a tight ±2% absolute tolerance, this ceramic-based network ensures reliable signal integrity in demanding circuits. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. The SOIC-C series construction features gull-wing terminations for robust surface-mount assembly, while the 0.4W total power rating (0.05W per resistor) balances compactness with thermal management.

GS4B032211GFT Features

• Bussed Design: Simplified PCB layout with shared connections, ideal for voltage division or pull-up/down networks.
• Thin Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
• Precision Tolerance: ±2% absolute and ±1% ratio tolerance ensure consistent performance in matched circuits.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation systems.
• Robust Packaging: Ceramic SOIC case (4.9mm × 5.99mm × 1.45mm) with ±0.1mm dimensional tolerances for precise placement.
• Non-Automotive Grade: Optimized for commercial/industrial use with EAR99 ECCN and non-PPAP compliance.

GS4B032211GFT Applications

• Signal Conditioning: Precision dividers in sensor interfaces or ADC/DAC circuits.
• Power Management: Voltage reference networks in DC-DC converters or LDO regulators.
• Industrial Controls: Bus termination or pull-up arrays in PLCs and motor drives.
• Test & Measurement: Calibration circuits requiring low TCR and tight tolerance matching.
• Aerospace & Defense: Non-critical subsystems where ceramic reliability is preferred.

Conclusion of GS4B032211GFT

The GS4B032211GFT excels in space-constrained, precision analog designs due to its thin-film accuracy, thermal stability, and compact SOIC footprint. While not RoHS-compliant, its ceramic construction and bussed architecture offer superior performance in industrial and instrumentation applications over generic resistor arrays. Engineers will value its balance of power handling, tolerance, and repeatability in mission-critical signal paths. For non-automotive designs requiring stable resistance networks, this model is a compelling choice.
