GS7B021872CAT Description

The GS7B021872CAT from TT Electronics/IRC is a high-precision Ceramic Resistor Network designed for demanding electronic applications. This 14-pin Narrow SOIC device features 13 bussed resistors with a 18.7KΩ resistance value, offering an absolute tolerance of ±0.25% and a ratio tolerance of ±0.05%. Built with thin-film technology, it ensures excellent stability and low noise, making it ideal for precision circuits. The SOIC package (8.66mm x 5.99mm x 1.45mm) with gull-wing termination enables easy surface-mount assembly, while its ceramic case provides superior thermal performance. Rated for 100V maximum voltage and 0.7W total power dissipation, it operates reliably across a -55°C to +125°C range, with derated power up to 125°C.
