GS4B022551DBT Description

The GS4B022551DBT 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 features a 2.55KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this 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.

GS4B022551DBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength vs. polymer-based arrays.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down networks.
• Extended Temperature Range: Stable performance from -55°C to +125°C (derated above 70°C).
• Automation-Friendly: Tube packaging ensures safe handling for pick-and-place assembly.
• Non-RoHS Compliant: Suitable for legacy or specialized industrial systems requiring leaded components.

GS4B022551DBT Applications

Ideal for:

• High-Speed Digital Systems: Bus termination in FPGA/ASIC interfaces to minimize signal reflection.
