GS4A037502GBT

GS4A037502GBT Description

The GS4A037502GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 75 kΩ resistance and a tight ±2% absolute tolerance. Its ±25 ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C derated, 125°C max). The SOIC package (4.9 x 5.99 x 1.45 mm) offers a compact footprint with gull-wing terminations for reliable surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power handling and space efficiency. The ceramic substrate enhances thermal performance, while the isolated circuit design minimizes crosstalk.
