GQ8A031132DAT

GQ8A031132DAT Description

The GQ8A031132DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 11.3K Ohm resistance with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The 16-pin gull-wing SMD design ensures secure surface mounting, while the 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A031132DAT Features

• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR for minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal stability and mechanical strength.
• High Power Handling: 0.75W total power rating (0.1W per resistor) with derating up to 125°C.
• Compact & Reliable: QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm length/height tolerances for consistent PCB integration.
• Isolated Design: 8 independent resistors (ISOL circuit) for flexible circuit design.
• Industry Compliance: HTS 8533.21.00.20, EAR99 ECCN, though non-RoHS (check alternatives for restricted applications).

GQ8A031132DAT Applications

• Analog Signal Conditioning: Ideal for precision dividers, feedback networks, and sensor interfaces in industrial controls.
• Medical Electronics: Stable performance in diagnostic equipment where resistance accuracy is critical.
• Automotive Systems: Suitable for non-automotive (PPAP No) but high-temperature environments like power management modules.
• Test & Measurement: Low TCR ensures minimal error in calibration circuits.
• Aerospace & Defense: Ceramic packaging withstands harsh conditions in avionics or communication systems.

Conclusion of GQ8A031132DAT

The GQ8A031132DAT excels in precision, power handling, and thermal resilience, making it a top choice for engineers requiring high-accuracy resistor networks in compact SMD formats. Its isolated thin-film design and ceramic QSOP package offer superior reliability over plastic-encased alternatives, though RoHS non-compliance may require alternative sourcing for regulated markets. Optimal for industrial, medical, and high-temperature applications where stability and miniaturization are paramount.
