GQCB012490JGT Description

The GQCB012490JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 23 resistors, each with a 249Ω resistance value and a 5% tolerance, delivering a total power rating of 1W (0.05W per resistor). Encased in a ceramic package, it ensures excellent thermal stability and durability, operating within a temperature range of 70°C to 125°C (derated) and a maximum operating temperature of 125°C. The ±100ppm/°C temperature coefficient guarantees stable performance under varying thermal conditions.

GQCB012490JGT Features

• High-Density Integration: 23 resistors in a compact QSOP-24 package (8.66mm × 6.02mm × 1.47mm), ideal for space-constrained designs.
• Thin-Film Technology: Delivers superior accuracy, low noise, and stable performance compared to thick-film alternatives.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm terminal pitch for high-density PCB layouts.
• Wide Voltage Range: Supports up to 100V maximum voltage rating, suitable for industrial and automotive-grade applications.
• Non-Compliant to EU RoHS: May be preferred for legacy or specialized systems requiring specific material properties.

GQCB012490JGT Applications
