GS4B013902CBT Description

The GS4B013902CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC gull-wing SMD package. Designed for BUS circuit applications, it offers a 39K Ohm resistance with an ultra-tight ±0.25% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a 70°C to 125°C derated power range. The ceramic case style and thin film technology provide excellent thermal performance, with a maximum operating temperature of 125°C and a 100V maximum voltage rating. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision applications requiring low-power dissipation (0.4W total, 0.05W per resistor) and miniaturized footprints (4.9mm x 5.99mm x 1.45mm).

GS4B013902CBT Features

• High Precision: ±0.25% tolerance and ±100ppm/°C TCR for stable performance in demanding environments.
• Robust Construction: Ceramic substrate and thin film technology ensure reliability under thermal stress.
• Compact Design: SOIC-8 package with 1.27mm terminal pitch, optimized for space-constrained PCB layouts.
• Wide Operating Range: 70°C to 125°C derated power range and 125°C maximum temperature for industrial use.
• Low Power Dissipation: 0.4W total power rating (0.05W per resistor) suits low-energy applications.
• Non-Compliant Options: EU RoHS non-compliant variant for legacy systems.
