GS7B032802FDT Description

The GS7B032802FDT 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 integrates 13 thin-film resistors, each with a 28KΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±25ppm/°C temperature coefficient and ±0.5% ratio tolerance make it ideal for precision analog circuits. The SOIC-C series construction features a ceramic case, gull-wing termination, and a compact footprint (8.66mm x 5.99mm x 1.45mm), suitable for space-constrained designs.

GS7B032802FDT Features

• High Precision: ±1% absolute tolerance and ±0.5% ratio tolerance for accurate signal conditioning.
• Robust Construction: Ceramic substrate and thin-film technology ensure stability and low noise.
• Wide Operating Range: Supports -70°C to +125°C with a 0.05W (1/20) power rating per resistor and 0.7W total power dissipation.
