GS4B037501DDT

GS4B037501DDT Description

The GS4B037501DDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC package, designed for surface-mount applications. It features a 7.5KΩ resistance per element with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) suits moderate-power circuits. With a 100V maximum voltage rating and 1.27mm terminal pitch, it balances compactness with reliability.

GS4B037501DDT Features
