GS4A021053JT Description

The GS4A021053JT from TT Electronics/IRC is a high-reliability ceramic resistor network designed for precision applications requiring stable performance under demanding conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 105 kΩ resistance value and a ±5% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and offers a low temperature coefficient of ±50 ppm/°C, ensuring minimal resistance drift. Encased in a rectangular ceramic SOIC package, it provides excellent thermal stability and mechanical durability, with a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor).

GS4A021053JT Features

• Isolated Resistor Network: Four independent resistors in an 8-pin SOIC package, ideal for signal isolation.
• High Stability: Thin-film technology with ±50 ppm/°C TCR ensures consistent performance across temperature fluctuations.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
