GQ0A034301GFT Description

The GQ0A034301GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 10-resistor array features a 4.3K Ohm resistance per element with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GQ0A034301GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for multi-channel isolation.
• Robust Ceramic Package: Withstands high temperatures (up to 125°C) and mechanical stress.
• Compact QSOP-20 Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal fluctuations.
• Automotive-Grade Alternatives Available: Though this variant is non-automotive (PPAP: No), similar models meet stricter standards.

GQ0A034301GFT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers, ADC/DAC reference circuits.
• Industrial Controls: PLCs, sensor interfaces requiring stable resistance values.
• Medical Equipment: Isolated measurement systems where reliability is critical.
• Telecom Infrastructure: Line termination, impedance matching in high-frequency PCBs.
