GS4B031003FDT Description

The GS4B031003FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for demanding electronic applications. Encased in a ceramic SOIC-8 package, it offers a 100KΩ 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). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this surface-mount (SMD) network is engineered for reliability in compact, high-density PCB designs. Its gull-wing termination and 1.27mm terminal pitch facilitate easy assembly, while the ceramic substrate enhances thermal and mechanical durability.

GS4B031003FDT Features

• Precision Thin-Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for stable signal conditioning.
• Robust Ceramic Package: Ensures high thermal conductivity and resistance to mechanical stress, ideal for harsh environments.
• Space-Saving SOIC-8 Design: Compact 4.9mm × 5.99mm × 1.45mm footprint with 8 gull-wing leads for automated SMT processes.
• Optimized Power Handling: 0.4W total dissipation (0.05W per resistor) supports moderate-power applications without derating up to 125°C.
• BUS Circuit Designator: Simplifies integration into bus line termination, voltage division, or pull-up/down networks.

GS4B031003FDT Applications

This resistor network excels in:

• Analog/Digital Signal Conditioning: Precision voltage dividers, feedback networks, and ADC/DAC interfaces.
