GQCA031581JFT Description

The GQCA031581JFT 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 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 1.58KΩ and a tolerance of ±5%. Encased in a durable ceramic package, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient and operates reliably across a -70°C to +125°C range. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this surface-mount network is ideal for compact, high-density PCB designs.

GQCA031581JFT Features

• Precision Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated Resistor Network (ISOL): Each of the 12 resistors is electrically isolated, enabling flexible circuit design.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability in harsh environments.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm terminal pitch for high-density layouts.
• Wide Temperature Range: Operates from -70°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress, critical for precision analog circuits.
