GQCA031150DCT

GQCA031150DCT Description

The GQCA031150DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter-Small Outline Package) device features 12 isolated resistors, each with a 115 Ω resistance, 0.5% tolerance, and a ±25 ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and reliability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the ±0.1mm dimensional tolerances facilitate consistent PCB placement.

GQCA031150DCT Features

• High Precision: 0.5% tolerance and ±25 ppm/°C TCR ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Resistors: 12 independent 115 Ω resistors with 100V isolation, ideal for signal conditioning and voltage division.
• Space-Efficient: QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space in compact designs.
• Reliable SMD Mounting: Gull-wing leads with 0.64mm pitch ensure solder joint integrity and ease of automated assembly.
• Wide Operating Range: -70°C to +125°C derated power range suits industrial and automotive-grade applications (though not PPAP/automotive-certified).
