GS4B026981CAT Description

The GS4B026981CAT is a high-precision 7-resistor bussed network from TT Electronics/IRC, designed for demanding surface-mount applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features a 6.98KΩ resistance value with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring minimal deviation in matched circuits. Its thin-film technology and ±50ppm/°C temperature coefficient deliver stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in precision analog and digital systems.

GS4B026981CAT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm × 5.99mm × 1.45mm) with gull-wing terminals for secure PCB mounting.
• High Precision: 0.25% tolerance and tight ratio matching (±0.05%) for critical signal conditioning.
• Thermal Stability: ±50ppm/°C TCR ensures minimal resistance drift.
• Bussed Design: Simplified PCB layout with 7 resistors connected to a common bus (BUS circuit designator).
• Derated Power Handling: Operates at 70–125°C with derated power, ideal for high-density boards.
• Non-Automotive Grade: Suitable for industrial, telecom, and test equipment (PPAP not required).

GS4B026981CAT Applications

This resistor network excels in:

• Precision Voltage Dividers: High-accuracy dividers in DAQ systems and instrumentation.
• Signal Conditioning: Stable performance in op-amp feedback networks and ADC/DAC interfaces.
• Industrial Controls: Reliable operation in PLC modules and power management circuits.
• Telecom Hardware: Low-noise resistance matching in RF front-end and filtering circuits.
• Test & Measurement: Critical for calibration equipment due to tight tolerance.

Conclusion of GS4B026981CAT

The GS4B026981CAT combines ceramic durability, thin-film precision, and thermal resilience for high-reliability applications. Its bussed architecture reduces component count, while sub-1% tolerance ensures signal integrity. Though non-compliant with EU RoHS, it remains a top choice for non-automotive precision electronics where stability and accuracy are paramount. Ideal for engineers seeking a cost-effective, high-performance network resistor in compact designs.
