GQ8A021400JCT Description

The GQ8A021400JCT 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 8-resistor isolated network features a 140 Ohm resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its versatility in circuit designs requiring robust power handling.

GQ8A021400JCT Features

• Thin-film technology: Delivers superior accuracy, low noise, and stable performance over time.
• Ceramic case style: Enhances thermal conductivity and mechanical strength, ideal for high-temperature applications.
• Gull-wing termination: Ensures reliable surface-mount (SMD) connections for automated PCB assembly.
• Isolated circuit design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Compact QSOP package (4.9mm x 6.02mm x 1.47mm): Saves board space while maintaining high power density.
• Wide temperature range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Low TCR (±50ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog and digital systems.
