GS4B021782BAT

GS4B021782BAT Description

The GS4B021782BAT 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 17.8KΩ resistance per element with an exceptional ±0.1% absolute tolerance and ±0.05% ratio tolerance, ensuring unmatched accuracy in signal conditioning and voltage division circuits. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable performance across industrial and automotive environments (though not PPAP/automotive-qualified). The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage support robust operation in compact designs.

GS4B021782BAT Features

• Precision Engineering: Thin-film technology with 0.1% tolerance and ultra-low TCR (±50ppm/°C) for minimal drift.
• Robust Construction: Ceramic case (SOIC package) with gull-wing termination, ensuring reliability in thermal cycling.
• Space-Saving: Compact 4.9mm × 5.99mm × 1.45mm footprint (±0.1mm length/height tolerance) ideal for high-density PCBs.
• Bussed Design: Simplified PCB routing with 7 resistors connected to a common bus, reducing component count.
• Wide Operating Range: Derated power up to 125°C, compliant with industrial-grade requirements (non-automotive).

GS4B021782BAT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks in op-amp circuits, and DAC/ADC interfaces.
• Industrial Control Systems: Signal conditioning in PLCs, sensor arrays, and test equipment requiring stable resistance ratios.
• Medical Electronics: Low-drift applications like patient monitoring devices, where accuracy is critical.
• Telecommunications: Impedance matching and termination in high-frequency modules.

Conclusion of GS4B021782BAT

The GS4B021782BAT excels in applications demanding high precision, thermal stability, and compactness. Its ceramic SOIC package and bussed architecture offer a balance of performance and design flexibility, though it lacks automotive certification. Ideal for engineers prioritizing tight tolerance (±0.1%) and low TCR in industrial, medical, or telecom systems, this resistor network reduces BOM complexity while ensuring long-term reliability. For non-automotive high-accuracy designs, it stands out among similar models for its ratio tolerance (±0.05%) and derated power handling up to 125°C.
