GS4B014221BBT Description

The GS4B014221BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a 4.22KΩ configuration with an ultra-tight 0.1% 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-8 package, this surface-mount (SMD) network offers a 0.4W total power rating (0.05W per resistor) and supports 100V maximum voltage. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB integration. The non-automotive, non-PPAP compliant device is supplied in tubes, making it suitable for prototyping and low-to-medium volume production.
