GS4B032490BBT Description

The GS4B032490BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 249Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it delivers 0.4W total power dissipation (0.05W per resistor) and supports 100V maximum voltage ratings. Its compact dimensions (4.9mm × 5.99mm × 1.45mm) and ±0.1mm length/height tolerances make it ideal for space-constrained PCB designs.
