GQ0A032211JFT Description

The GQ0A032211JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 10-resistor array features a 2.21KΩ resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit designs. The ceramic case and isolated (ISOL) circuit designator enhance thermal and electrical stability, while the surface-mount (SMD) form factor simplifies PCB integration.

GQ0A032211JFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Construction: Ceramic substrate ensures durability and efficient heat dissipation.
• Space-Efficient QSOP Package: Compact 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for high-density layouts.
