GQ8A032802BT Description

The GQ8A032802BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers 28KΩ resistance per element with an exceptional ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design provides individual resistor independence, making it ideal for precision analog circuits. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network balances performance and reliability in compact surface-mount (SMD) designs.

GQ8A032802BT Features

• High Precision: ±0.1% tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Ceramic case with gull-wing terminations ensures durability and solderability.
• Isolated Resistors: Independent 28KΩ resistors (8 total) enable flexible circuit design without crosstalk.
• Space-Efficient: Compact QSOP package (4.9mm x 6.02mm x 1.47mm) suits high-density PCB layouts.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade applications (though non-PPAP).
• Low Noise: Thin-film technology minimizes parasitic effects, critical for analog signal integrity.

GQ8A032802BT Applications

This resistor network excels in:

• Precision Voltage Dividers: Used in ADC/DAC reference circuits due to its tight tolerance.
• Medical Instrumentation: Isolated resistors prevent signal interference in sensitive diagnostic equipment.
• Industrial Controls: Stable performance in PLCs and sensor interfaces under thermal stress.
• Telecom Infrastructure: High-frequency signal conditioning in base stations and RF modules.
• Test & Measurement: Calibration circuits requiring long-term drift resistance.

Conclusion of GQ8A032802BT

The GQ8A032802BT stands out for its precision, isolation, and compact form factor, making it a superior choice over bulkier or less stable alternatives. While not RoHS-compliant, its ceramic construction and thin-film technology deliver reliability in harsh environments. Engineers will value its low TCR and high power density for critical analog designs where space and accuracy are paramount. Ideal for high-end industrial and instrumentation use, though not automotive-qualified.
