GQ0A034221JAT

GQ0A034221JAT Description

The GQ0A034221JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 4.22KΩ resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding environments.

GQ0A034221JAT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive circuits.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk.
• Robust Ceramic QSOP Package: Enhances thermal performance and mechanical durability.
• Wide Temperature Range: Derated power operation up to 125°C suits industrial and automotive-adjacent applications.
• Gull-Wing SMD Termination: Facilitates automated assembly and secure PCB mounting.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation use where PPAP compliance isn’t required.

GQ0A034221JAT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers in ADC/DAC circuits.
