GS4A0275R0JT

GS4A0275R0JT Description

The GS4A0275R0JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated 75Ω thin-film resistors, each rated at 0.1W (1/10W) with a ±5% tolerance and a low ±50ppm/°C temperature coefficient. The device operates within a wide temperature range of 70°C to 125°C, derated for optimal performance, and supports a maximum voltage rating of 100V. Its SOIC package (4.9mm x 5.99mm x 1.45mm) ensures compact surface-mount integration, while gull-wing terminations facilitate reliable PCB connections.
