GQCA031153GT

GQCA031153GT Description

The GQCA031153GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 115K Ohm resistance, 2% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic substrate, the device offers superior thermal stability and durability, making it ideal for harsh environments. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) gull-wing termination.
