GS4B034420FDT Description

The GS4B034420FDT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 442 Ω resistance per resistor with a tight 1% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this non-automotive, non-PPAP compliant component is ideal for precision circuits requiring low drift and high reliability. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.

GS4B034420FDT Features

• Ceramic SOIC-8 case for robust thermal and mechanical stability.
• Thin film technology ensures low noise and high accuracy (±25 ppm/°C).
• BUS circuit designator simplifies routing in bus-oriented systems.
• 0.4W total power rating (0.05W per resistor) with derating up to 125°C.
• 1% tolerance and 442 Ω resistance for precision applications.
• Gull-wing leads and 1.27mm pitch for reliable SMT assembly.
• Non-RoHS compliant (suitable for legacy or exempted designs).
