GS7B0139R0GT Description

The GS7B0139R0GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 14-pin narrow SOIC package features 13 bussed resistors with a 39Ω resistance value and a tight ±2% tolerance, ensuring reliable performance in demanding circuits. Built with thin-film technology, it offers excellent stability with a ±100ppm/°C temperature coefficient. The device operates within a wide temperature range of -55°C to +125°C, with derated power handling up to 125°C. Its 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-density PCB designs.

GS7B0139R0GT Features

• Ceramic substrate for enhanced thermal and mechanical stability.
• Bussed network topology simplifies bus line termination and pull-up/down applications.
• Thin-film resistors deliver superior accuracy and low noise compared to thick-film alternatives.
• Gull-wing termination ensures reliable surface-mount soldering.
• Compact SOIC package (8.66mm × 5.99mm × 1.45mm) with tight dimensional tolerances (±0.1mm length/height).
• Non-compliant with EU RoHS, making it suitable for legacy or exempted applications.
• Automotive-grade alternatives available (though this variant is not PPAP-certified).

GS7B0139R0GT Applications
