GQCA038451CBT Description

The GQCA038451CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP surface-mount device integrates 12 isolated resistors, each with a 8.45KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in circuit matching. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±25ppm/°C temperature coefficient and a 125°C maximum operating temperature. The gull-wing termination and 0.64mm pitch facilitate reliable PCB mounting, while the 1W total power rating (0.1W per resistor) supports robust performance in compact designs.

GQCA038451CBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors with 100V maximum voltage rating, ideal for isolation barriers.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical strength vs. plastic alternatives.
• Tight Tolerances: ±0.25% resistance and ±0.1mm dimensional tolerances ensure repeatable performance.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suited for industrial environments.
