GS8A0245R3DDT Description

The GS8A0245R3DDT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 45.3Ω thin-film resistors with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.5%, this network ensures exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination facilitates reliable PCB mounting. With a ±50ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it balances precision with durability.
