GS4A0297R6DDT

GS4A0297R6DDT Description

The GS4A0297R6DDT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Built with ceramic substrate and thin-film technology, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and ±0.5% absolute tolerance. Each resistor offers 97.6Ω resistance with a 0.1W (1/10) power rating per element (0.4W total). The device operates across a wide temperature range (-70°C to +125°C), making it suitable for demanding environments. Its gull-wing termination and surface-mount design (SOIC package) ensure easy PCB integration, while 100V maximum voltage rating enhances reliability in high-voltage circuits.

GS4A0297R6DDT Features

• Precision Performance: Tight ±0.5% tolerance and low TCR (±50ppm/°C) ensure accuracy in signal conditioning and feedback networks.
• Robust Construction: Ceramic case provides superior thermal and mechanical stability compared to polymer-based networks.
• Isolated Design: Independent resistors (non-bussed) allow flexible circuit configurations without crosstalk.
• Compact & Reliable: 4.9mm × 5.99mm footprint with ±0.1mm length/height tolerances for high-density layouts.
• Wide Operating Range: Derated power up to 125°C suits automotive, industrial, and telecom applications (though non-PPAP and non-automotive graded).

GS4A0297R6DDT Applications

Ideal for precision analog circuits, including:

• Voltage dividers and current sensing in power supplies.
• ADC/DAC reference networks requiring low drift.
• Medical instrumentation where stability and isolation are critical.
• Industrial control systems exposed to temperature fluctuations.
• Telecom infrastructure (e.g., impedance matching in RF modules).

Conclusion of GS4A0297R6DDT

The GS4A0297R6DDT excels in high-accuracy, thermally stable applications due to its ceramic thin-film construction and isolated resistor design. While not RoHS-compliant or automotive-qualified, its 0.5% tolerance, 100V rating, and wide temperature range make it a standout choice for precision electronics where reliability and miniaturization are paramount. Engineers should consider this model for critical analog circuits demanding long-term stability under harsh conditions.
