GQ8A031243FFT

GQ8A031243FFT Description

The GQ8A031243FFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers 124K Ohm resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and compact surface-mount (SMD) gull-wing termination. The ceramic case ensures durability and thermal performance, while the QSOP package (4.9mm x 6.02mm x 1.47mm) suits space-constrained designs.
