GS4B012212GFT Description

The GS4B012212GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 22.1KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring excellent matching accuracy. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor make it suitable for stable operation across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The 100V maximum voltage rating and 0.4W total power dissipation enhance reliability in high-voltage and power-sensitive designs.

GS4B012212GFT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances ensures mechanical stability and thermal performance.
• Bussed Network Design: Simplifies PCB layout by connecting resistors in a common bus configuration, reducing component count.
• Thin-Film Technology: Delivers superior precision, low noise, and stable performance compared to thick-film alternatives.
• Gull Wing Termination: Facilitates surface-mount (SMD) assembly with a 1.27mm terminal pitch for compatibility with automated PCB processes.
• Wide Temperature Range: Operates reliably from -55°C to 125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Non-RoHS Compliance: Suitable for legacy or specialized systems requiring leaded components.

GS4B012212GFT Applications

This resistor network excels in:

• Voltage Divider Circuits: Precision ratio tolerance (±1%) ensures accurate signal conditioning in sensor interfaces and ADCs.
• Bus Termination Networks: High-voltage tolerance (100V) and low TCR (±100ppm/°C) make it ideal for communication line termination.
• Industrial Control Systems: Ceramic construction resists thermal stress in harsh environments (e.g., motor drives, power supplies).
• Test & Measurement Equipment: Thin-film technology minimizes drift, critical for calibration and instrumentation.

Conclusion of GS4B012212GFT

The GS4B012212GFT stands out for its precision, durability, and space-saving design, offering engineers a reliable solution for high-accuracy analog circuits. Its ceramic package and thin-film resistors provide long-term stability, while the bussed configuration simplifies design complexity. Though not RoHS-compliant or automotive-grade, it remains a top choice for industrial, telecom, and precision electronics where performance outweighs regulatory constraints. For designs demanding tight tolerances and robust thermal performance, this network delivers exceptional value.
