GS4A033651CBT

GS4A033651CBT Description

The GS4A033651CBT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding analog and signal conditioning applications. Built with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and ±0.25% absolute tolerance (±0.1% ratio tolerance). The 3.65KΩ resistors are rated for 0.1W (1/10W) per element (0.4W total), operating reliably from 70°C to 125°C at derated power. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in surface-mount designs. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with tight tolerances (±0.1mm length/height, ±0.2mm depth), making it ideal for space-constrained PCBs.

GS4A033651CBT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for critical analog circuits.
• Isolated Design: Independent resistors (non-bussed) enable flexible circuit configurations.
• Robust Construction: Ceramic case and thin-film technology ensure long-term reliability.
• Wide Temperature Range: Operates up to 125°C with derating, suitable for industrial environments.

• Compact SOIC Package: Space-saving 8-pin narrow SOIC (1.27mm pitch) for high-density layouts.
• Non-Automotive: Not PPAP-capable, but ideal for industrial, medical, and test equipment.

GS4A033651CBT Applications

• Precision Voltage Dividers: High-ratio tolerance (±0.1%) suits reference circuits.
• Signal Conditioning: Isolated resistors for op-amp feedback networks or sensor interfaces.
• Medical Instrumentation: Stable performance in diagnostic equipment.
• Industrial Controls: Reliable operation in PLCs and process monitoring systems.
• Test & Measurement: Low-drift resistance for calibration modules.

Conclusion of GS4A033651CBT

The GS4A033651CBT excels in applications requiring high precision, thermal stability, and compactness. Its ceramic thin-film construction and isolated resistor design provide superior performance over polymer-based networks, particularly in environments with fluctuating temperatures or stringent accuracy requirements. While not automotive-grade, it is a cost-effective solution for industrial, medical, and lab equipment where tight tolerances and low drift are critical. Engineers will appreciate its balance of miniaturization, reliability, and electrical performance in advanced analog systems.
