GS4B036491CT

GS4B036491CT Description

The GS4B036491CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and a tight ±0.25% tolerance. The network operates across a 70°C to 125°C derated power range, with a maximum voltage rating of 100V and a total power dissipation of 0.4W (0.05W per resistor). Its SOIC-C series construction ensures reliability in demanding environments, though it is not PPAP or automotive-qualified.

GS4B036491CT Features

• Precision Performance: 6.49KΩ resistance with ±0.25% absolute tolerance for critical analog/digital circuits.
• Robust Construction: Ceramic case and thin-film technology ensure low noise and high stability.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with gull-wing terminations for easy surface mounting.
• Wide Thermal Range: Operates up to 125°C with derated power handling at elevated temperatures.
• Bussed Design: Simplifies PCB layout by connecting resistors in a common bus configuration.

GS4B036491CT Applications

Ideal for precision electronics requiring stable resistance networks, such as:

• Voltage dividers and reference circuits in test/measurement equipment.
• Signal conditioning in industrial control systems.
• Feedback networks for op-amps and ADCs/DACs.
• Medical devices where low drift and high accuracy are critical.
• Aerospace/defense subsystems (though RoHS non-compliance may limit use in some regions).

Conclusion of GS4B036491CT

The GS4B036491CT excels in applications demanding high precision, thermal stability, and compactness. Its ceramic thin-film design and bussed architecture offer superior performance over standard thick-film networks, making it a preferred choice for engineers prioritizing accuracy and reliability. While not suited for automotive use, it remains a robust solution for industrial, medical, and instrumentation designs.
