GS4B028871FT

GS4B028871FT Description

The GS4B028871FT 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 resistance. With a 1% tolerance and ±50ppm/°C temperature coefficient, it ensures reliable performance across a 70°C to 125°C operating range. The 8.87KΩ resistance per element, combined with a 100V maximum voltage rating, makes it suitable for signal conditioning, voltage division, and pull-up/down circuits. Its ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.05W (1/20) power rating per resistor (0.4W total) balances compactness with efficiency.

GS4B028871FT Features

• Precision Thin Film Technology: Delivers ±1% tolerance and low TCR (±50ppm/°C) for stable operation.
• Bussed Network Design: Simplifies PCB layout with shared connections (BUS circuit designator).
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm height/length tolerances ensures durability.
