GS4B0251R0FT

GS4B0251R0FT Description

The GS4B0251R0FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. Featuring a 51Ω resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, this ceramic-based network ensures reliable performance across a -70°C to +125°C operating range. Its 0.05W (1/20W) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-voltage circuits. The SOIC-C series construction offers robust mechanical stability with a compact footprint (4.9mm x 5.99mm x 1.45mm), ideal for space-constrained designs.

GS4B0251R0FT Features

• Bussed Network Topology: Simplifies PCB layout by connecting resistors in a common bus configuration.
• Thin-Film Technology: Delivers superior stability, low noise, and precise tolerance (±1%) compared to thick-film alternatives.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• High Voltage Tolerance: Supports up to 100V, making it suitable for industrial and automotive (non-AECQ) applications.
• Compact SOIC Package: Gull-wing termination and 1.27mm pitch ensure compatibility with automated SMT processes.
