GS4B021370DBT Description

The GS4B021370DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 137 Ohm resistance value with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package, it offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) save board space.
