GQ8A034121FFT

GQ8A034121FFT Description

The GQ8A034121FFT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it features 4.12KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD design offers reliable surface-mount compatibility, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for demanding circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design further enhance its versatility in complex electronic systems.

GQ8A034121FFT Features

• Precision Thin Film Technology: Delivers stable performance with ±25ppm/°C TCR and 1% tolerance for critical analog/digital circuits.
• Robust Ceramic QSOP Package: Ensures durability and thermal efficiency in high-temperature environments (up to 125°C).
• High-Density Integration: 8 resistors in a compact 4.9mm x 6.02mm x 1.47mm footprint, ideal for space-constrained PCBs.
• Gull-Wing Termination: Facilitates reliable surface-mount assembly with a 0.64mm terminal pitch for automated placement.
• Isolated Design (ISOL): Each resistor is electrically independent, enabling flexible circuit configurations.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
