GS4B029100JDT Description

The GS4B029100JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features 7 bussed resistors with a 910Ω resistance value and a ±5% absolute tolerance, ensuring reliable performance in demanding circuits. Built with thin-film technology, it offers excellent stability with a ±50ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. The SOIC package provides a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates within a -70°C to +125°C temperature range, though derating is required above 70°C.

GS4B029100JDT Features

• Ceramic substrate for enhanced thermal and mechanical stability.
• Bussed network topology simplifies circuit design by connecting multiple resistors to a common node.
• Low TCR (±50ppm/°C) ensures minimal resistance drift under thermal stress.
• 5% tolerance with ±0.5% ratio tolerance for balanced performance in divider circuits.
• 0.05W power rating per resistor (0.4W total) with 125°C maximum operating temperature.
• RoHS non-compliant (contains lead), suitable for legacy or industrial systems.
• Tube packaging for automated pick-and-place assembly.
