GS4B025900FBT Description

The GS4B025900FBT 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 590Ω resistance per element with a tight 1% tolerance and a low ±50ppm/°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 network is ideal for signal conditioning, voltage division, and impedance matching in compact PCB designs. Its gull-wing termination and 1.27mm pitch facilitate reliable soldering, while the ceramic substrate enhances thermal stability and durability.

GS4B025900FBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±1%) for critical analog circuits.
• Robust Ceramic Package: Ensures thermal endurance and mechanical strength in harsh environments.
• BUS Circuit Design: Simplifies multi-point biasing or pull-up/down configurations in digital systems.
• Space-Efficient SOIC-8: Compact 4.9mm × 5.99mm × 1.45mm footprint suits high-density layouts.
• Wide Operating Range: Stable performance from -55°C to +125°C (derated above 70°C).
• Automotive-Grade Alternatives: While this model is not PPAP/AEC-Q200 qualified, similar variants exist for automotive use.
