GS4B028660FFT

GS4B028660FFT Description

The GS4B028660FFT 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 thin-film technology construction with a 866Ω resistance value and tight ±1% absolute tolerance (±1% ratio tolerance). Its ±50ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust performance in compact designs. The gull-wing termination and surface-mount compatibility (1.27mm pitch) facilitate easy PCB integration.

GS4B028660FFT Features

• Ceramic Case (SOIC-C): Enhances thermal stability and durability vs. plastic alternatives.
• Bussed Network (7 Resistors): Simplified circuit design for common voltage division or pull-up/down applications.
• Precision Thin Film: Delivers low noise and high accuracy (±1% tolerance, ±50ppm/°C TCR).
• High-Temp Operation: Rated up to 125°C, ideal for industrial or automotive-adjacent systems (non-automotive PPAP).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Non-RoHS: Suitable for legacy or specialized applications requiring non-compliant materials.

GS4B028660FFT Applications
