GQCA033900JFT Description

The GQCA033900JFT 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 package features 12 isolated resistors, each with a 390Ω resistance value and a tight ±5% tolerance. The ceramic case style ensures excellent thermal stability, with an operating temperature range of 70°C to 125°C and a ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating provide robust performance in compact surface-mount designs.

GQCA033900JFT Features

• Isolated Circuit Design (ISOL): Ensures minimal crosstalk between resistors, critical for signal integrity in high-density circuits.
• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• Ceramic Package: Enhances thermal dissipation and mechanical durability in harsh operating conditions.
• Gull Wing Termination: Facilitates reliable SMT assembly with a 0.64mm terminal pitch for high-density PCB layouts.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C), suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Precision Tolerances: ±0.1mm height/length tolerances ensure consistent mounting alignment.
