GS4B027501JT

GS4B027501JT Description

The GS4B027501JT 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 surface-mount applications. It features a 7.5KΩ resistance per element with a ±5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature 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 ensure robust connectivity in demanding environments.

GS4B027501JT Features

• Ceramic Case & SOIC Package: Enhances thermal stability and mechanical durability.
• Bussed Network Design: Simplifies PCB layout with shared common terminals (BUS).
• Precision Thin Film: Offers tight tolerance (±5%) and low TCR (±50ppm/°C).
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its robustness suits industrial applications.
