GQCA034532BT Description

The GQCA034532BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 45.3 kΩ resistance value and an ultra-tight 0.1% tolerance. Encased in a ceramic package, it offers excellent thermal stability and reliability, with a ±25 ppm/°C temperature coefficient and a power rating of 0.1W per resistor (1W total). The gull-wing termination ensures secure surface-mount (SMD) assembly, while its 100V maximum voltage rating and 125°C maximum operating temperature make it suitable for high-performance circuits.

GQCA034532BT Features

• Precision Performance: 0.1% tolerance and ±25 ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• High-Density Design: QSOP-24 package (8.66 x 6.02 x 1.47 mm) saves PCB space while providing 12 isolated resistors.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power.
• Surface-Mount Ready: Gull-wing leads with 0.64 mm pitch simplify automated assembly.
