GS4B031212BBT Description

The GS4B031212BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 12.1KΩ configuration with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, this network offers 0.4W total power dissipation (0.05W per resistor) and a maximum voltage rating of 100V. Its compact dimensions (4.9mm x 5.99mm x 1.45mm) and ±0.1mm length/height tolerances make it ideal for space-constrained designs.
