GS4B011500DDT Description

The GS4B011500DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 150 Ohm configuration with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic SOIC package, this 8-pin gull-wing SMD component offers excellent thermal stability and reliability, making it ideal for precision circuits. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it suits compact, high-density designs. The EU RoHS non-compliant status should be noted for regulatory considerations.
