GQ0A021801GBT

GQ0A021801GBT Description

The GQ0A021801GBT 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 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.8KΩ resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, making it suitable for demanding environments. With a power rating of 1W (0.1W per resistor) and a ±50ppm/°C temperature coefficient, this network ensures reliable performance across a wide temperature range of -70°C to +125°C. The gull-wing termination facilitates easy surface-mount (SMD) assembly, while the 100V maximum voltage rating enhances its versatility in high-voltage circuits.

GQ0A021801GBT Features

• Precision Thin-Film Technology: Delivers low noise and high stability for sensitive analog and digital circuits.
• Isolated Resistor Configuration (ISOL): Each of the 10 resistors operates independently, eliminating crosstalk.
• Robust Ceramic Package: Ensures excellent heat dissipation and mechanical strength.
• Wide Operating Range: Functions reliably from -70°C to +125°C, even at derated power.
• Compact QSOP Form Factor: 8.66mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) for space-constrained designs.
• High Power Handling: 1W total (0.1W per resistor) with a 100V rating, ideal for power-sensitive applications.
• Gull-Wing SMD Termination: Simplifies PCB assembly and improves solder joint reliability.
