GS4A0188R7GDT Description

The GS4A0188R7GDT 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 thin-film resistors, each with a resistance value of 88.7Ω and a tight ±2% absolute tolerance, ensuring consistent performance. The device operates within a wide temperature range of 70°C to 125°C and offers a ±100ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, it balances power handling and compactness. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination ensures reliable surface-mount assembly.
