GS4A024220GT

GS4A024220GT Description

The GS4A024220GT from TT Electronics/IRC is a high-reliability 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable performance under demanding conditions. This ceramic-based thin-film resistor network offers a 422Ω resistance per element with a tight ±2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. The SOIC-C series construction provides isolated elements, making it suitable for circuits requiring independent resistor paths. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it balances compactness (4.9mm × 5.99mm × 1.45mm) with robust performance. The gull-wing termination ensures reliable surface-mount assembly, while the ceramic case enhances thermal and mechanical stability.
