GS4B021200FT

GS4B021200FT Description

The GS4B021200FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 120Ω resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination enable robust surface-mount integration in space-constrained designs.

GS4B021200FT Features

• Ceramic SOIC Package: Offers excellent thermal and mechanical stability, ideal for harsh environments.
• Bussed Network (BUS): Simplifies circuit design by interconnecting resistors, reducing component count.
• Precision Thin Film: Ensures low noise, high accuracy (±1%), and minimal TCR drift (±50ppm/°C).
• High-Temperature Operation: Rated for 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• 1.27mm Terminal Pitch: Compatible with standard SOIC PCB layouts.
