GS4B025490DBT Description

The GS4B025490DBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC gull-wing SMD package. Designed for BUS circuit applications, it offers a 549Ω resistance value with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style enhances durability, while the 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a tube, this non-automotive, non-PPAP component is ideal for precision analog and digital circuits.

GS4B025490DBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive applications.
• Compact SOIC Package: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• High Power Density: 0.4W total dissipation (0.05W per resistor) in a small footprint.
• Wide Operating Range: -55°C to +125°C with derating up to 125°C, outperforming many standard networks.
• Robust Construction: Ceramic substrate and gull-wing termination ensure reliability under thermal and mechanical stress.
• Non-RoHS Compliant: Suitable for legacy or specialized industrial systems where RoHS exemptions apply.
