GQCA011800GFT Description

The GQCA011800GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP package integrates 12 isolated 180Ω resistors with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount assembly, while the 1W total power rating (0.1W per resistor) supports moderate power dissipation. With a 100V maximum voltage rating, this network is ideal for signal conditioning, voltage division, and isolation circuits in industrial and telecom systems.

GQCA011800GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, minimizing crosstalk.
• Compact QSOP Package: Measures 8.66mm x 6.02mm x 1.47mm, optimizing board space in dense layouts.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Robust Construction: Ceramic substrate ensures thermal durability, while gull-wing leads enhance solder joint reliability.
• Low TCR (±100ppm/°C): Maintains resistance accuracy under thermal stress.
