GQCA024302DBT Description

The GQCA024302DBT 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 43K Ohm resistance and an ultra-tight 0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.1W (1/10) power rating per resistor and 1W total power rating make it suitable for precision circuits.

GQCA024302DBT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR ensure stable performance in temperature-variable environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Resistors: 12 independent resistors (ISOL circuit design) prevent crosstalk in sensitive analog/digital systems.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch simplify PCB integration.
• Wide Voltage Range: Supports up to 100V maximum voltage, ideal for industrial and instrumentation use.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
