GQ0A0188R7FFT

GQ0A0188R7FFT Description

The GQ0A0188R7FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation circuit applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 88.7Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision analog and digital circuits. The ceramic case construction enhances thermal stability, while the ±100ppm/°C temperature coefficient minimizes resistance drift across its operating range of 70°C to 125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (1W total), it balances compactness (8.66mm × 6.02mm × 1.47mm) with robustness.

GQ0A0188R7FFT Features

• Isolated Resistor Network: 10 independent resistors in a single QSOP package, ideal for signal isolation.
• High Precision: 1% tolerance and thin-film technology ensure low noise and stable performance.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Ceramic Substrate: Enhances thermal conductivity and mechanical durability.
• Gull Wing Termination: Facilitates automated SMD assembly and reliable solder joints.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.

GQ0A0188R7FFT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in instrumentation.
• Isolation Circuits: Buffering and impedance matching in communication interfaces.
• Medical Electronics: Patient monitoring systems requiring stable, noise-free resistance paths.
• Test & Measurement Equipment: Calibration and reference circuits demanding low TCR.
• Industrial Controls: PLCs and sensor interfaces where space efficiency and reliability are critical.

Conclusion of GQ0A0188R7FFT

The GQ0A0188R7FFT combines miniaturization, precision, and thermal resilience, making it a standout choice for isolation-focused designs. Its ceramic construction and thin-film technology outperform comparable epoxy-based networks in high-temperature environments. While not RoHS-compliant, it remains a cost-effective solution for non-regulated industrial and commercial applications. Engineers will appreciate its balance of density (20-pin QSOP) and performance, particularly in space-constrained, high-reliability systems.
