GS4B034320FBT Description

The GS4B034320FBT 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 432Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this BUS-designated network is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal performance.

GS4B034320FBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength compared to polymer-based arrays.
• Extended Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Space-Efficient SOIC-8: Compact 4.9mm × 5.99mm footprint with a 1.45mm profile, ideal for high-density designs.
• Automated Assembly Friendly: Gull-wing leads and ±0.1mm length/height tolerances ensure pick-and-place compatibility.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and instrumentation applications.
