GS4A036652JBT Description

The GS4A036652JBT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 66.5kΩ resistance per element with a ±5% absolute tolerance and an exceptional ±0.1% ratio tolerance, this thin-film ceramic-based network ensures superior stability and accuracy. Its ±25ppm/°C temperature coefficient and 100V maximum voltage rating make it ideal for precision analog circuits. The SOIC-C series construction provides robust thermal performance, operating reliably from 70°C to 125°C at derated power. With a 0.1W power rating per resistor (0.4W total), gull-wing termination, and compact 4.9mm × 5.99mm × 1.45mm footprint, it balances performance with space efficiency.
