GQCB016190FT Description

The GQCB016190FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. Encased in a 24-pin QSOP ceramic package, this 23-resistor array offers a 619Ω resistance per element with a tight 1% tolerance and ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -55°C to +125°C. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with compact surface-mount (SMD) gull-wing termination. The ceramic substrate enhances thermal performance, while the QSOP package (8.66mm x 6.02mm x 1.47mm) suits space-constrained designs.
