GQCA0254R9JGT Description

The GQCA0254R9JGT 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 resistors, each rated at 54.9Ω ±5% tolerance, with a ±50ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures. The ceramic case construction enhances thermal stability, while the 1W total power rating (0.1W per resistor) supports robust performance in compact designs. Rated for 100V maximum voltage and operating from 70°C to 125°C, it is ideal for environments demanding tight electrical and thermal tolerances.

GQCA0254R9JGT Features

• Isolated Resistor Network: 12 independent thin-film resistors in a single 24-pin QSOP package, reducing PCB footprint.
• Precision Stability: ±50ppm/°C TCR and 5% tolerance ensure consistent performance under thermal stress.
• High Power Handling: 1W total (0.1W per resistor) with derated operation up to 125°C.
• Robust Construction: Ceramic substrate and gull-wing SMD termination for mechanical durability and solderability.
• Automated Assembly Friendly: 0.64mm terminal pitch and surface-mount design streamline high-volume production.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.
