GS7A0139R2JGT

GS7A0139R2JGT Description

The GS7A0139R2JGT from TT Electronics/IRC is a high-performance 7-resistor isolated network in a 14-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Built with ceramic substrate and gull-wing terminations, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient and 5% absolute tolerance. Each resistor provides 0.1W (1/10W) power dissipation, totaling 0.7W for the network, and operates within a wide temperature range of 70°C to 125°C (derated) or up to 125°C maximum. Its 39.2Ω resistance value and 100V maximum voltage rating make it suitable for signal conditioning, voltage division, and isolation circuits. The SOIC-C series construction ensures robust mechanical integrity, with tight dimensional tolerances (±0.1mm length/height, ±0.2mm depth).

GS7A0139R2JGT Features

• Isolated Resistor Network: 7 independent thin-film resistors in a single package, eliminating mismatched performance.
• High Precision: ±5% absolute tolerance and ±2% ratio tolerance for consistent signal accuracy.
• Robust Construction: Ceramic case and gull-wing terminations enhance durability and solderability.
• Thermal Stability: ±100ppm/°C TCR ensures minimal resistance drift under temperature fluctuations.
