GS7B028872CBT Description

The GS7B028872CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration network integrates 13 thin-film resistors, each with a 0.25% absolute tolerance and a tight ±50ppm/°C temperature coefficient. The device offers a resistance value of 88.7KΩ with a ratio tolerance of ±0.1%, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Its SOIC-C series construction provides robust performance in a compact 5.99mm x 8.66mm footprint, making it suitable for space-constrained designs. Rated for 100V maximum voltage and 0.7W total power dissipation, it operates reliably across a -55°C to +125°C temperature range, with derated power up to 125°C.
