GS4B033482FBT Description

The GS4B033482FBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for demanding circuit applications. Encased in a ceramic SOIC-8 package, it offers a 34.8KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital systems. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic substrate enhances thermal performance and durability.

GS4B033482FBT Features

• High Precision: 1% tolerance and ±25ppm/°C TCR for stable performance in varying environments.
• Robust Construction: Ceramic case and thin film technology ensure reliability under thermal stress.
• Compact Design: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for space-constrained layouts.
• Automotive-Grade Alternatives: While not automotive-certified, its 125°C maximum temperature suits industrial and telecom applications.
• Efficient Power Handling: 0.4W total dissipation (distributed across 7 resistors) balances performance and thermal management.
