GQ0A036490DAT

GQ0A036490DAT Description

The GQ0A036490DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 10-resistor array features an isolated (ISOL) circuit design, providing individual resistor isolation for enhanced signal integrity. With a 649Ω resistance value and tight 0.5% tolerance, it ensures reliable performance in precision circuits. The ceramic QSOP package offers excellent thermal stability, while the gull-wing termination facilitates secure surface-mount (SMD) assembly. Rated for 1W total power dissipation (0.1W per resistor) and operating within a -70°C to +125°C temperature range, this component is ideal for environments requiring stable resistance under thermal stress.

GQ0A036490DAT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C temperature coefficient ensure minimal drift.
• Robust Construction: Ceramic case and thin-film technology provide superior durability and thermal performance.
• Isolated Design: Independent resistors (ISOL) prevent crosstalk, ideal for multi-channel systems.
• Space-Efficient: Compact QSOP-20 package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch suits high-density PCBs.
• Wide Voltage Range: Supports up to 100V, making it versatile for analog and digital circuits.
• Stable Power Handling: 0.1W per resistor (1W total) with derating up to 125°C.

GQ0A036490DAT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces.
• Industrial Electronics: PLCs, motor controls, and instrumentation requiring stable resistance.
• Telecommunications: Signal conditioning and impedance matching in RF modules.
• Medical Devices: High-reliability systems where accuracy and thermal stability are critical.
