GQ0A0190R9GFT Description

The GQ0A0190R9GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 20-pin QSOP package integrates 10 isolated resistors, each rated at 90.9Ω with a 2% tolerance, delivering a combined power rating of 1W (0.1W per resistor). The ceramic case and gull-wing termination ensure reliable surface-mount (SMD) compatibility, while the ±100ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a maximum voltage rating of 100V, this network is ideal for signal conditioning, voltage division, and impedance matching in demanding environments.

GQ0A0190R9GFT Features

• Precision Thin Film Technology: Offers superior stability and low noise compared to thick-film alternatives.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in multi-channel circuits.
• High Power Density: 1W total dissipation (0.1W per resistor) in a compact 8.66mm × 6.02mm × 1.47mm footprint.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, derated for high-temperature operation.
• Robust Construction: Ceramic substrate enhances thermal management and mechanical durability.
• Gull Wing Termination: Ensures secure PCB mounting and solder joint integrity.

GQ0A0190R9GFT Applications

• Industrial Electronics: PLCs, motor drives, and sensor interfaces requiring precision resistance networks.
• Telecommunications: Impedance matching and termination in high-frequency RF modules.
• Medical Devices: Signal processing circuits where stability and low drift are critical.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical systems needing isolated resistors.
• Test & Measurement Equipment: Calibration and reference circuits due to its tight tolerance (±2%).

Conclusion of GQ0A0190R9GFT
