GS4B034222FDT Description

The GS4B034222FDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 42.2K Ohm resistance per element with a tight 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 an 8-pin SOIC ceramic 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.
