GS4B034872FT

GS4B034872FT Description

The GS4B034872FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 48.7KΩ resistance per element with a tight ±1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-voltage circuits. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and gull-wing termination facilitate easy PCB integration.

GS4B034872FT Features

• Ceramic case (SOIC package) for enhanced thermal stability and durability.
• Bussed network (BUS designator) simplifies circuit design by connecting resistors in a common configuration.
• Low TCR (±25ppm/°C) minimizes resistance drift under temperature fluctuations.
• High precision (±1% tolerance) ensures consistent performance in critical applications.
• 0.4W total power rating and 100V max voltage support robust operation.
• RoHS non-compliant (note for restricted applications).
• Tube packaging for secure handling and storage.

GS4B034872FT Applications

Ideal for precision analog circuits, voltage dividers, and signal conditioning in:
