GS4A021002GFT

GS4A021002GFT Description

The GS4A021002GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 10KΩ resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient, ensuring minimal drift in harsh environments. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for demanding circuits. Encased in a rectangular ceramic SOIC package, it offers superior thermal dissipation and mechanical durability compared to polymer-based networks.

GS4A021002GFT Features

• Isolated Resistors: Four independent 10KΩ resistors with isolated elements, reducing crosstalk in signal conditioning.
• High Stability: Thin-film technology and ±50ppm/°C TCR ensure precision over temperature fluctuations.
• Robust Construction: Ceramic case enhances thermal performance and longevity in high-stress environments.
• Surface-Mount Design: Gull-wing termination and 1.27mm pitch enable compact PCB layouts.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive-adjacent applications.
• Strict Tolerances: ±2% absolute and ±1% ratio tolerance for matched resistance pairs in differential circuits.

GS4A021002GFT Applications

• Signal Isolation: Precision voltage dividers or feedback networks in op-amp circuits and ADC/DAC interfaces.
• Industrial Controls: PLC systems and sensor conditioning modules requiring stable resistance under thermal cycling.
• Power Management: Current sensing and load balancing in power supplies (non-automotive).
• Test & Measurement: Calibration circuits where low drift and matched ratios are critical.
• Medical Electronics: Isolated signal paths in diagnostic equipment (note: non-RoHS compliance may restrict use in some regions).

Conclusion of GS4A021002GFT

The GS4A021002GFT excels in applications demanding high precision, thermal resilience, and electrical isolation. Its ceramic construction and thin-film resistors provide superior performance over plastic-encased networks, particularly in industrial, instrumentation, and power systems. While not PPAP or automotive-qualified, its wide temperature range and low TCR make it a reliable choice for prototyping and non-automotive harsh environments. Engineers should verify RoHS compliance for regulated markets.
