GS4A024421BT Description

The GS4A024421BT from TT Electronics/IRC is a high-precision 4-resistor network designed for demanding isolation applications. Housed in an 8-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a tight tolerance of ±0.1% and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. With a 4.42KΩ resistance value per resistor, it delivers 0.1W power dissipation per element (0.4W total) and supports 100V maximum voltage rating, making it suitable for precision analog and signal conditioning 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.
