GS4B038451FFT

GS4B038451FFT Description

The GS4B038451FFT 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. This thin-film resistor network offers a 8.45KΩ resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring excellent matching accuracy. Its ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable performance in thermally challenging environments. The 0.05W (1/20W) power rating per resistor and 100V maximum voltage rating provide reliable operation in low-power circuits.

GS4B038451FFT Features

• Ceramic Case & Thin Film Technology: Ensures high reliability, low noise, and superior thermal stability compared to thick-film alternatives.
• Bussed Network (BUS Design): Simplifies circuit layout by connecting resistors in a common configuration, reducing PCB complexity.
• Precision Tolerance: ±1% absolute and ratio tolerance for critical analog/digital signal conditioning.
• Wide Temperature Range: Derated power operation from 70°C to 125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Robust Construction: Gull-wing termination and SOIC package (4.9mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances ensure consistent solderability.
• Non-RoHS Compliant: Suitable for legacy or niche applications requiring non-compliant materials.

GS4B038451FFT Applications

• Voltage Division & Pull-Up/Down Networks: Precision dividers in ADC/DAC circuits.
• Signal Conditioning: Buffering and impedance matching in communication systems.
• Industrial Controls: Stable reference networks in PLCs and sensor interfaces.
• Test & Measurement Equipment: High-accuracy resistor networks for calibration.
• Legacy Electronics: Non-RoHS compliant designs where ceramic stability is prioritized.

Conclusion of GS4B038451FFT

The GS4B038451FFT excels in precision applications requiring tight tolerance, thermal stability, and compact packaging. Its ceramic thin-film construction and bussed design offer distinct advantages over generic networks, particularly in environments with fluctuating temperatures or stringent matching requirements. While not suited for automotive use, it is a robust choice for industrial, instrumentation, and high-reliability consumer electronics. Engineers will appreciate its balance of performance, size, and cost in space-constrained designs.
